Error starting VM after update 6.2-4

[Alexandre Aguirre]

Hello good day !

I have a LAB for testing, and it was with the Proxmox VE version 6.1-8, and I upgraded to 6.2-4, however, my containers went up everything ok, but my Windows VM does not generate this error when connecting it:



I think I should update Qemu, but how do I do it without the VM turning on?

do you have nested pve ? and do you have ignore_msrs active?
if yes then this is a kernel bug, see https://bugzilla.kernel.org/show_bug.cgi?id=206877

for now you'd have to disable ignore_msrs again

Hello, thanks for the feedback!

Could you tell me how to disable ignore_msrs ?

 

[dcsapak]

did you not enable it yourself? normally it is put in /etc/modprobe.d/somefile.conf with the line

options kvm ignore_msrs=Y

just remove the line and run 'update-initramfs -u' and reboot
