unable to clone VMs

[Sylvain.D]

Hello everybody,

Maybe someone can help me.

I have an hypervisor Proxmox 7.4-3 connected to a SCSI SAN by ISCSI (LVM).
Since few days i encounter a problem to clone VMs, every VMs are Windows 10, and clone opérations are clean.
But all cloned VMs cannot boot (UEFI boot crash, system seems to be not able to view system volume).
if i attach disk cloned to a clean VM, i can see the volume but it in dirty state.

I checked SAN log ans all is OK.
I have make the same test with internal server storage storage (local-thin) and clone boot properly.

i post pveversion :

Hi,
did you change anything a few days ago (e.g. upgrade)? Do you have the guest agent installed in the VM and enabled? Otherwise the file system might not be in a clean state when finishing the clone. Does it work if you clone while the VM is offline? Is there anything in /var/log/syslog around the time of the operation?

 

[Sylvain.D]

Nothing have been changed or updated, it's a fresh install of 7.4-3.
Guest agent is installed ans enable in proxmox ans guest VM.
Clone test have been made with offline VMs.
No error found in /var/log/syslog

Guest agent is installed ans enable in proxmox ans guest VM.

You don't need to install the guest agent in Proxmox VE directly, it's only intended for the guests. The only case you need it, would be if Proxmox VE itself runs as a VM

Clone test have been made with offline VMs.

That shouldn't lead to broken disks of course (if the source disk is not already broken).

Can you post the output of qm config 112 and cat /etc/pve/storage.cfg?

Since few days i encounter a problem to clone VMs, every VMs are Windows 10, and clone opérations are clean.
But all cloned VMs cannot boot (UEFI boot crash, system seems to be not able to view system volume).

Try downgrading the pve-edk2-firmware package or use a different CPU Type than host or disable memory hotplug. I could not find information about your VM configurations or your host system, so I'm just guessing.
