Configured scratch location doesn't work after upgrade to ESXi 6.5

Hi,
My configured scratch location for some reason doesn't work after upgrading to ESXi 6.5.

I set up parameter ScratchConfig.ConfiguredScratchLocation to a persistent storage. The folder exists and worked before the upgrade.

After each reboot ScratchConfig.CurrentScratchLocation is always set to /scratch while ScratchConfig.ConfiguredScratchLocation is /vmfs/volumes/volume01/scratches/host01

I'm not sure if this is related but to upgrade ESXi I had to provide boot parameter preferVmklinux=TRUE as my USB drive wasn't visible and later I run these commands:

esxcli system settings kernel set -s preferVmklinux -v FALSE

esxcli system module set --enabled=false –m vmkusb

 

Thanks for your help in advance,

Lukasz

Intel Union Point-H AHCI Controller cannot passthrough

I found that my onboard AHCI controller cannot passthrough. The Chipset is Intel 200 series, I can see the AHCI controller in DriectIO pannel, but the passthrough column is "not capable".

 

Here is some information:

ID 0000:00:17.0

Device ID 0xa282

Vendor ID 0x8086

Class ID 0x106

 

esxcli system module get -m vmw_ahci

 

   Module: vmw_ahci

   Module File: /usr/lib/vmware/vmkmod/vmw_ahci

   License: BSD

   Version: 1.2.0-6vmw.670.0.0.8169922

   Build Type: release

   Provided Namespaces:

   Required Namespaces: com.vmware.vmkapi@v2_5_0_0

   Containing VIB: vmw-ahci

   VIB Acceptance Level: certified

 

I also tried to add the DID and VID to /etc/vmware/passthru.map but nothing happened.

 

So I don't know is NOT the AHCI controller supported passthrough?

 

p.s. I also can get the correct disks info with ls -l /vmfs/devices/disks

 

Does anyone meet the same issue? Or have the same requirement for passthrough with this AHCI controller?

 

Thank you very much.

Help needed: Hardware for Homelab server running ESXi

Hi guys,

 

I'm planning to get my first server for my homelab.

As I need an environment for the preparations for my Cisco CCIE certification.

I also want to run some of my services hosted @ home on this ESXi.

 

I want to build a server with an i7-8700 and want to pass through the integrated Intel GPU to one of my VMs.

Do I need to go with a C232/C236 mainboard in order to get full feature support with ESXi or is a consumer chipset like Z170 etc also doing fine?

As I read the C232 does not support the integrated Intel GPU, but my question is:

 

Is only the graphics output of the integrated GPU not supported

or

the integrated GPU at all is not supported?

Is the C232 chipset (like on Gigabyte GA-X150M-Pro) able to passtrough the integrated GPU to the ESXi, or do I have to go with C236(or maybe consumer chipset like Z170) chipset?

 

Are there any other problems that you might see with my setup?

 

I plan to get the following setup:

 

Core i7-8700

64GB DDR4 RAM

4x GbE ESXi supported NIC card

ESXi supported RAID controller

 

Thank you in advance for your support!

 

PS: Hope this is in the right subcategory, if not, please move it to the right one.

ESXi 6.5 - USB HID Devices into Guest VM

June 3, 2017, 3:15 pm

Hello Everyone,

 

I'll start by saying I've spent the last few days consistently trying to find a solution to my problem.  If the answer is obviously out there, I'm sorry, cause I missed it.

 

My host has ESXi 6.5 installed on it.  I want one of the VMs to function as my (physical) desktop computer.  I have successfully passed through my GTX 1060 (PCIE GPU), so when I boot the VM up, it beautifully displays on my physical monitor.  The drivers successfully installed too.

 

My challenge now is to get a physical keyboard and mouse dedicated to the Windows VM, rather than the console.  My Windows VM has a USB controller.  With that said, here is my thought process:

 

- When I add a "USB Device", HID (mouse and keyboard) devices are not shown.  My SanDisk Cruzer USB drive immediately shows up, but neither my Microsoft media keyboard, or my 2 other usb periphrials (1 mouse 1 keyboard) show up to pass through.  However, when I SSH into my ESXi server, and I run the command "lsusb", all the devices (including keyboards) show up. So this tells me my host is recognizing it, but intentionally not allowing it to be passed through.

 

I read online that this is intentional, so you accidentally don't lock yourself out of your console.  I am perfectly happy with my console not responding to my keyboard.  I found a few flags online, to put in the VMX file of the VM, but these did not work.  I tried rebooting my host.

 

I thought of passing through the entire USB interface.  The Web Admin only shows that I have 1 USB Controller (Intel).  It is not capable of pass through (greyed out).  I think this is because the console has confiscated it, do the usb driver can run.  So there is nothing I can simply pass through.

 

I tried reverting to the legacy USB drivers (disable the new VMKUSB driver) , by using SSH, and entering, "esxcli system module set -m=vmkusb -e=FALSE".  When I enter this command, and reboot my host, the only usb device I see is "intel bluetooth", which is obviously confusing for me.

 

I don't have another PCIE slot to put in a USB hub, so I think my only option at this point is to figure out a way for HID devices to be allowed as USB devices by ESXi.  It's comically ridiculous that it's this hard to simply plug a usb device into a VM.

 

I have only been using the Web Admin.  I tried installing the VMware client for windows, but it is not supported by my version of ESXi (6.5)

 

Thank you for reading my question.  I really appreciate your time and help!

ESXi 6.7 - Frustrated and bewildered: All settings reset to default after reboot

Behavioral issues with ESXi 6.7 --

 

Discovered when trying to passthrough a cougar point SATA controller on my motherboard - it's a supermicro X9SCL-F, so it doesn't have ACS, but passthrough had been working since ESXi 5.5.

 

I toggle the SATA controller to passthrough, reboot.  Upon reboot, passthrough disabled.

 

I thought maybe it was the fault of the VMKernel.boot.disableACScheck = false flag, so I set it to true.  Reboot, flag set to false again.

 

I tried setting a VM to autostart.  Reboot, VM not set to autostart anymore.

 

Does anybody know what's going on?  Is this how it's supposed to behave?  Google appears to be turning up nothing.

VMware ESXi 6.5 Installation fails with Error

May 1, 2018, 9:33 am

Dear Community,

 

       Please bare with me, for I am new to hypervisor operation(s). As such, I may make simple mistakes along the way. I purchased a Dell Precision T7500 from a 3rd party recently, with the following specifications:

 

  • CPU :: (1x6crs.) Intel Xeon X5650
  • RAM :: (6x2GB) 12GB DDR3

                   NOTE :: 3 active memory channels

  • GPU :: (1x) nVIDIA GeForce GTX 550 Ti

                   (1x) nVIDIA GeForce GT 520

  • SFX :: (1x) Creative 'SoundBlaster' Audigy 2
  • STR :: (1x) 4TB HDD

                  (1x) 500GB HDD

                  (1x) 320GB HDD

 

In addition to this, I should be receiving a CPU/RAM riser and a 2nd (identical) CPU in the mail in a few days/weeks. In that case, I'll have 2 of the same CPU in this workstation instead of one - and that will be the only thing changing. During the installation, I attempted to install ESXi to the 4TB HDD, to no avail. Here is a video of how my installation went:

 

ESXi Install Attempt :: Part I - YouTube

 

The final error that I arrive at is:

  • Unable to successfully execute 'tryFormatDevice' after 3 tries

I've searched across Google, and have only arrived at one possible solution:

 

Expand the LUN (size?) from 8GB to 16GB.

 

Possibly related topic: ESX 6.5 is unable to format a partition when installing on iSCSI.

 

But, how does one expand/extend LUN? Is it in BIOS? Is it something that must be performed in the installer? Please help.

How do you list IOMMU groups in ESXi?

May 1, 2018, 4:47 pm

I'm tearing my hair out trying to determine if I have a conflict in my IOMMU groups because I can't figure out how to list them in ESXi. I ran "find -name '*iommu*'" and only got 1 result: /usr/lib/vmware/vmkmod/dma_mapper_iommu. This, and the lack of /sys/ leave me quite a bit confused as to how this info is meant to be obtained.

 

The issue I'm having is a VM won't boot with both the GPU and USB controller being passed through. With only 1 of the 2 it works fine. I think it's an issue with the IOMMU groups, but I can't verify. Feel free to shame me if the answer is simple as I've been searching for about an hour now.

 

EDIT: After some more testing the problem I'm having with the VM is unlikely to be related to IOMMU. I can't get the VM to boot with the USB controller passed through at all. Still curious about how I can check IOMMU groups in ESXi though.

Admin access for only the resource pool in vSphere

Hi all,

 

I have created a resource pool in my vSphere with 3 hosts, managed by a vCenter server with HA and DRS enabled (screenshot below) for a project with friends. I  would like to give admin access to 4 of my friends only to that resource pool.

 

 

I have tried giving permission to 4 of them with admin role to that resource pool but they still can't create VMs or import/deploy OVF templates. When they log into vSphere, they can only see their resource pool (screenshot below) which is what I want but I cant seem to give them admin access for that resource pool.

 

 

 

What am I missing?

 

Thanks

Hi,

 

I've encountered an issue on ESXi 6.5 U1 where my vm would just power off randomly. The error i'm getting on the event log is VMware ESX unrecoverable error: (vmx) PCI passthru device 0000:86:02.0 caused an IOMMU fault type 5 at address 0x10d24a000). After that, any vm with that pcie device would not power on. Has anyone encountered this before? or does anyone know what IOMMU fault type 5 relates to?

Reducing disk size

A Windows VM used to host 200 GB of data.

Now the used space is 40 GB as a lot of data were deleted.

How can I reduce the size of the (thin) .vmdk files?

The VM is member of an AD domain and this makes things a little bit more complicated.

Can I use any PowerCli command or any backup tool?

How does vSAN work for esxi 6.7

 

is it where it shares storage from each esxi host in a cluster.

or

is it where you can have a storage array with say 20 SSD in a raid 5 and install vm's across the raid array. and it connects to it over the network or via fiber cables on the back of a blade center say?

How clone mechanism is in vSAN environment

Hello,

 

As everyone knows,  each VM will have two duplicate in vSAN environment if SPBM set FTT=1.

 

We can clone VM in vsandatastore. but internal mechanism for clone which is not clear to us.

 

As I guess, Clone will concurrent to copy two duplicate in vsandatastore, but can not explain more detail.

 

Everybody who mastering vSAN clone mechanism give more comments will be appreciated !

 

 

there are three scenarios as below we can discussing it .

 

1) clone to local esxi host in vsandatastore 

2)clone to other host in vsandatastore

3)cross-cluster clone

Quiesece snapshot creates two delta files

Hi All,

 

If you take a snapshot of VM (with 1 HDD on it) ---- if you go to ESXi Command line (putty) and to the VM folder and do a ls -lthr *.vmdk

 

You would only see 1 delta.vmdk (which is the snapshot file) ; Today I realized that when I take a quiesce snapshot and do a ls -lthr *.vmdk ; there are delta files that get created?

 

 

 

Any suggestions why two delta files are getting created

 

 

Thanks

Hi,

 

I encounter an issue with my server since I've installed the ESXi 5.5.0 build 4722766 update (was on build 3248547).

 

The error message displayed is:

 

"No compatible network adapter found. Please consult the product's Hardware Compatibility Guide (HCG) for a list of supported adapters."

 

My motherboard is a Supermicro X10SDV-4C-TLN2F with integrated NIC.

 

Is there a way to add network drivers?

hi community,

 

how does the persistent memory work on ESXI 6.7 and how can one set it up?

 

im assuming its for eg using memory in a server to install a VM onto i'm guessing? as when you create a VM and get to the customize hardware option and add new device you can add a NVDIMM and select the size in MB or GB what you want but it says i don't have any persistent memory.

Unable to Delete Snapshot or Consolidate Disks Esxi 6.5 - Unable to access file since it is locked

Trying to Consolidate Disk or delete snap shots to be able to convert VMware to Hyper V. Have already done this with a different VM on the same Esxi Host and worked correctly.

 

Getting error:

Failed - Unable to access file since it is locked

Errors:   An error occurred while consolidating disks: One of the disks in this virtual machine is already in use by a virtual machine or by a snapshot.

 

&

 

Remove all the snapshots associated with this virtual machine

Failed - A general system error occurred: vim.fault.GenericVmConfigFault

 

What I've tried so far:

Restarting ESXI host, services, making a copy of the VM and attempting on the copy. I can create a new Snapshot fine, but I am not able to delete the newly created snapshot. I do not have another Esxi Host to try migrating too. I do not have access to the former backup software the company used. The VM does work fine and I do have a backup. Unable to recreate the VM as it has Windows Server 2003 with customized software and limited support.

 

Software being used to convert: 5nine Vmware to Hyperv, errors saying their are snapshots on the VM.

 

Any help would be appreciated.

Failed to expand VMFS datastore... - Cannot change the host configuration

May 4, 2018, 12:58 am

Dear reader

 

I am a sys-admin with 'some' VMware knowledge. Our IT partner helped us increase the server capacity with two additional drives.

First drive was added to the raid volume, the second one is branded as hot spare when one crashes.

 

The expanding via the ESX of the raidvolume worked perfectly. In Vcenter I can even see that VMware finds that the volume has increased.

Now, the following problem arises :

 

When trying to expand the existing Datastore:

- via the Vcenter directly it does not show any disk/LUN volume and you cannot continue.

- via the direct connection to the server:

     * it lets me use <Expand an existing VMFS datastore extent>

     * I can select <Local LSI Disk (naa...) Disk 3.27TB...

     * it shows me <Select partitioning options> where it shows me the 3.VMFS in blue and <Free space> 837.84GB in green.

     * when selecting the blue VMFS, you can see on the <After> that blue and green merges

     * when trying to finish it ends in the error "Cannot change the host configuration".

 

I have found that the GPT table was not as should be on the disk and I fixed this. Sadly enough that did not fix it.

I have checked the permissions for the logins I am using, being root & administrator, both have rights, doesn't change anything.

Going via Vcenter doesn't work, going via Server ends in error.

 

My IT Partner doesn't know the answer to this either and now suggest to update the hardware raidcontroller's drivers etc.

 

Vcenter: Version information: Version 6.5.0 Build 7515524

Selected servers (2 - Live & Backupserver (identical- Fujitsu RX2520 M1)) to upgrade: Hypervisor: VMware ESXi 6.5.0, 5969303

 

PS: This morning I saw the following under <Configure>

Local USB Direct-Access (mpx.vmhba32...) disk 3,73GB Attached HDD Block Adapter
Local LSI Disk (naa.6003...) disk 3,277TB HDD SAS

 

I personally don't know where to look anymore, any help would be welcome =)
