Migrating from KVM to Proxmox - "VolGroup00 not found" and kernel panic

[f.somenzi]

Hi everyone. I'm new in the forum and very low experienced in VMs in general.
I am trying to migrate an operational virtual machine running an old release of Centos (kernel 2.6.9-89 EL) in a KVM environment, to Proxmox.
I took the .img file from the source server, copied in proxmox and imported to local-lvm using the "qm importdisk" command. I managed to set it as bootdisk. Once started, it goes to "kernel panic" because it doesn't find "VolGroup00". You can find attached the error.
What should I do to overcome this error?
Thank you

looks like you changed the disk bus (scsi, ide, sata)?

=> use the same configuration on your Proxmox VE VM config and I assume you can boot.

(such issues does not exists on newer Linux distribution)

Yes, you were right. I changed the disk bus to ide0 and it started correctly.
The problem now is that the X server, the desktop environment doesn't start correctly. It generates an error. I will try to go deep into it. Thank you
