[SOLVED] Linux VM don't start after upgrading to Proxmox 6.2

[Spaylia]

Hi,

I just installed Proxmox 6.2 and all my Linux-based VM (or at least all the Debian-based) don't start anymore, only the FreeBSD ones do.
They're all in UEFI mode and I get this message when I start them and open noVNC:

BdsDxe: failed to load Boot0002 "UEFI QEMU QEMU HARDDISK " from PciRoot(0x0)/Pci(0x1E,0x0)/Pci(0x1,0x0)/Pci(0x5,0x0)/Scsi(0x0,0x0): Not Found
BdsDxe: failed to load Boot0001 "UEFI QEMU DVD-ROM QM00003 " from PciRoot(0x0)/Pci(0x1F,0x2)/Sata(0x1,0xFFFF,0x0): Not Found

If I install a new one with the same configuration (Debian, UEFI, same disk size, same VirtIO SCSI, etc), it works without any problem, but I don't really want to install all my servers one by one.

I don't really know what to do, I tried changing the VirtIO SCSI to "Default (LSI 53C895A)" but it doesn't solve anything, the first line of the above message disappear. Any suggestions?

Thanks!

Hi,

this was an unavoidable regression for certain OS types when fixing an issue with how efi-vars-disk got handled.

See https://pve.proxmox.com/wiki/Roadmap#_6.2_known_issues_ovmf and for how to fix it use the following guide:

Thank you very much for the solution, it works perfectly!

I have tried this and it does not work. It will not show the drive that has the file in it. I believe i'm missing a small EFI drive to access the main drive and this file within the virtual drive. I have also tried this https://forum.proxmox.com/threads/vms-wont-boot-after-upgrade.69440/#post-311422 but my conf file doe not even have the machine parameter in it.


Any other suggestions ? I would really appreciate any help on this one ...
