VM shutdown, KVM: entry failed, hardware error 0x80000021

Can you try disabling SMM?
To do so you'll have to run the VM manually. First run qm showcmd <VMID> --pretty and copy the content to a file.
Modify the -machine line by adding ,smm=off.
Then run that command.


One more question, do all of you use UEFI with pre-enrolled keys and perhaps even secure boot?
The VM is running Server 2022 so yes UEFI with pre-enrolled keys.
 
We're now trying to reproduce it here with Windows Server 2022 and pre-enrolled keys.
Is there any specific software you're running in the VMs that run into this assertion?

Any load we could try to reproduce?
 
Throwing my hat in the ring for this issue ... well it looks like the same issue to me.

Let me know what I can contribute.

We're running a single Windows server 2022 VM on a new Dell T350 and just experienced this issue this morning, early AM.

A backup job finished at 3:39:52 and then the 2022 VM crashed at 3:46:58.

Other notes:
- The server isn't in production yet and is only running our standard management software package ... remote control, patch management, backup, etc.
- The server ran with the same software in our office for two weeks with no issue.
- Two days ago it was placed into a small office environment with considerable traffic on th network.
- Yesterday at 9:17AM memory use within Windows reached 24GB, the size that is set in the VM. Windows was attempting to defragment the VM disks. I disabled this task and the utilization immediately dropped to less than 8GB.

best,

James

hi
I have the same problem on Proxmox 7.2.4 and Windows Server 2022 VM. Suddenly it shuts down. The hyper-v service is not active and I find it in the log. No particular service is installed, all very standard, just a few shared folders and a management software.

To do so you'll have to run the VM manually. First run qm showcmd <VMID> --pretty and copy the content to a file.
Modify the -machine line by adding ,smm=off.
Then run that command.
Turning off SMM causes the VM to start but not POST (yes, I did launch swtpm manually), so I'm afraid this is not a viable test for VMs that require secure boot.

If it helps, here are potentially relevant kvm arguments you may want to use in trying to reproduce this problem:
  • -machine type=pc-q35-6.1+pve0
  • -smp 1,sockets=1,cores=12,maxcpus=12
  • -cpu host,+hv-tlbflush,hv_ipi,hv_relaxed,hv_reset,hv_runtime,hv_spinlocks=0x1fff,hv_stimer,hv_synic,hv_time,hv_vapic,hv_vpindex,+kvm_pv_eoi,+kvm_pv_unhalt
  • -numa node,nodeid=0,cpus=0-11,memdev=ram-node0
  • -drive if=pflash,unit=0,format=raw,readonly=on,file=/usr/share/pve-edk2-firmware//OVMF_CODE_4M.secboot.fd
  • -tpmdev emulator,id=tpmdev,chardev=tpmchar
  • -device tpm-tis,tpmdev=tpmdev

Nothing special. Even OS installation gets irrecoverably interrupted, I had to repeat it 3 times. Looks like disabling CFG (Control flow guard) on guest makes crashes less often, maybe by three times. There may be more types of illegal instructions causing VM crash.
Steps to reproduce are just to install OS, connect it to internet and download and install updates. I experienced several crashes during this process.
 
I just confirmed that simply downgrading the kernel to 5.13.19-6—with all other things unchanged—completely resolves the issue for me.

On kernel 5.15.35-1 my VM would invariably crash during Windows startup or shortly thereafter (before I could even log in), so in my particular case it's very quick and easy to know whether the problem is still there or not.

Now that I think about it I had vanilla windows server 2019 VMs crash on me too but I don't know if those crashes were caused by the same thing. I'll spin up a couple and see if any of them crash.

[Edit] I tried starting up my two domain controller testing VM's that are both running server 2019 (UEFI, no secure boot) and one of them crashed within 10 seconds of starting up with the error "hardware error 0x80000021" in the syslog. That VM won't even start up anymore, the crash bricked the VM that hard. Thankfully I've got a backup. I'll try using a 5.13 kernel.

This has been reported by others for 5.15.13 before here: https://old.reddit.com/r/VFIO/comments/s1k5yg/win10_guest_crashes_after_a_few_minutes/

Sadly, this happened for me too. Interestingly, this has only happened on single Windows 11 VM (21H1, 22000.xxx) but not on a Server 2019 (1809, 17763.xxxx), suggesting that this is something that occurs on newer builds only. Both VMs use same CPU configuration/args and both have TPM attached along with VBS enabled and running. In both cases Core Isolation is disabled as it is too slow when running on older hardware within VM.

There was nothing special happening on VM that crashed, it was idling with OpenVPN and single RDP session open. The time of crash is about few minutes after Veeam B&R scans entire AD network. While this VM has no backups configured it does have agent installed. I was able to crash it second time later on by manually scanning it (which basically only checks if B&R can ping device, if agent is installed and up-to date). Very unsure if this is related or not, as the crashes happened minutes after the fact, while actual scan takes few seconds at most. Possibly related to something that Windows kernel tries to do when switching from idling to working and back to idling (newer builds, and especially Windows 11, have more advanced kernel scheduling; also Server 2019 VM pretty much always does something so it never really idles below 1%)?

Downgrading to 5.13.19 is a solution that works for me (been over two weeks now since going back).

In case you need more information, here's my setup:

VM 109 is Windows 11 that was crashing, VM 100 is Server 2019.
 
We're now trying to reproduce it here with Windows Server 2022 and pre-enrolled keys.
Is there any specific software you're running in the VMs that run into this assertion?

Any load we could try to reproduce?
Im running WinServer 2022 with MSSql server 2019 with small database under 10G, the VM crashed regularly, other VM with WinServer 2022 serving as windows fileserver does not crash, meaning on the same Proxmox instance
 
I am also experiencing the issue once every few days on a Dell T630 and Win2022/Win11 VM's. It's usually a domain controller or an exchange server that crashes, but had other computers crash too. VM's have no pcie passthrough, have nothing special really.

Now I downgraded to 5.13.19-6-pve and disabled nested virtualization. Will monitor the situation.
 
As I wrote in German forum: I am having two VM Windows Server 2022 on the pve with the 5.15.35-1 Kernel. One with and one without the Microsoft May updates. The VM with the updates crashes the other one is stable. Could someone confirm that the crashes are only with Microsoft May updates?

The following ISO has this issue even during OS installation, with network not configured and internet not yet reachable. The only thing to select/customize is Datacenter with GUI (last in the list). It's the 180 day evaluation version of WS 2022. I doubt it already has any May updates.

Adding my crashing to the pile...

I have a Windows 11 VM that passes through an NVME drive, GPU, (2) USB controllers and a SATA controller. I run a WindowsImageBackup to a Samba share that lives on a ZFS pool on the Proxmox host. This backup runs at 4:00AM on Sunday and this morning I woke to an offline guest.

Some notes:
  • I had previously pinned 5.13.19-6-pve to resolve some issues with GPU passthrough.
  • I got a workaround functional, unpinned the kernel and rebooted on 5/10. (At this point I was running kernel version 5.15.35-2.)
  • The backup on 5/15 didn't fail.
  • On 5/17 I updated the kernel to version 5.15.35-2.
With the 5.13.19-6-pve kernel unpinned, running the WindowsImageBackup will always make it crash.

My syslog snippet follows, let me know if I can provide any more information to help get this resolved.

Did some tests with WS 2022 installation.
Made it to the select partition for install screen, with VirtIO SCSI driver loaded. Format partition went OK. I left opened this screen for 24 hours. As soon as I confirmed and the installation started, in like 5 seconds the VM crashed. It seems is related to disk I/O.
