I remember seeing a bug in get_hv_cpuid on the KVM mailing list at some point, it should have been fixed in newer kernels though. That also explains why switching to "Linux" fixes it, since that disables the Hyper-V extensions for the VM.

Try rebooting the node to load the new 5.3 kernel included in 6.1, then your VM should run with OS type "Windows" as well.

I just shut down the remaining windows vms and rebootet the host machine on a planned downtime during noon.
After the reboot everything works fine again - all windows vms came up fine :)

Do you use ZFS? If yes, it's rather a harmless warning which will disappear with a upcomming ZFS update. But yes it looks pretty scary, sorry for that:

Add
Code: 
# echo "zfs zfs_vdev_scheduler=none" >> /etc/modprobe.d/zfs-no-vdev-sched.conf
then:
#  update-grub
or if UEFI is used:
# pve-efiboot-tool refresh


EDIT: see https://github.com/zfsonlinux/zfs/issues/9417#issuecomment-548085631

I've solved this problem. In fresh installed servers i don't have /etc/apparmor.d/tunables/proc file.
Just copied from other server, and lxc container start.

That looks like an ECC memory error. Probably a faulty RAM module, maybe try a memtest and replace it.

Very unlikely that it has to do with the update though, it probably just manifested because of the reboot...
 
Our containers don't start via GUI since Upgrade to Proxmox 6.1:

But we can start the containers manually in foreground mode with:

Can someone help?
 
6.1 Still clock jumps for me :/
After the reboot command clock is in the future.

I am having the same problem on some servers and it causes some processes like pveproxy to go into D state and become unresponsive.

Then it's not the same cause, as that just produces a single such warning at boot during ZFS module load, after that there are no effects - if it's this specific "issue". So how does your warning looks like, would be good to see with a bit before and after kernel log.

Still, if itsn't related to that bug then I am getting some FUSE crashes too which send pveproxy into D state:

Never said that your issue isn't valid, just that it's surely not this one.

Can you restart the pve-cluster.service? Any IO errors? Maybe it'd be best to open another thread for this.
The first of such a message would be interesting too.
 
Hi,
after upgrading to 6.1 we are experiencing problems with online VM migration with local disks on ZFS storage. This worked for us in 5.4 from console using "qm migrate <VMID> <HOST> --online=true --with-local-disks".

I must say that this is happening on a cluster which got upgraded from 5.4 directly to 6.1. In our test cluster which was updated from 5.4 to 6.0 and then from 6.0 to 6.1 this is not happening.

Migrate command: qm migrate 12401 node24 --online=true --with-local-disks

Problem details:
A migration error at the very end of the migration with message: unable to open file '/etc/pve/nodes/node21/qemu-server/12401.conf.tmp.13207' - Permission denied. This aborted migration leaves the VM in a frozen and locked state. We had to unlock it with qm unlock and then stop/start.

Migrate log:

Hi,
I can't be 100% sure that it was quorate, but that made me think a little. I made more tests and once in a while the migration passed, but often failed. I switched the migration network to a different network not shared with PVE/Corosync and it started working more predictably. Probably during the migration the node lost Quorum and that was the reason of the error. Thanks for the suggestion, I'll report back if I find more problems.
