Unable to boot proxmox VM

Hi all,

I have Centos-7.6 and Ubuntu-18.04 VM, They work fine after the installation.
But after few days, I am unable to boot the VM (No bootable Media Found) after a shutdown, or after a restore from backup.
When checking with Rescue Linux, i found that my partition table on VM was erased.

At the beginning I thin that it was due to a misconfiguration in the VM. But the same behavior on the 2 VM make me think that the problem is on Proxmox.

I use PVE 5.3-8.

What do you think about guys ???
Proxmox VE does not automatically access VM volumes, especially not their content.

What underlying storage do you use, can you post the output of following commands:

qm config <VMID>        # replace <VMID> with real ID from both
pvesm status

Or do you re-used the VM disk image somewhere?

thanks for your answer,

Of course, i have created template from both OS and I run many VM from the same template.
I've found workaround by dumping the MBR on a fresh instance (using DD) and restore it on the failed VM.
However, it's not safe to often rewrite MBR.

so, What may be the root cause ?

Here is the output for the Ubuntu VM:

For the Centos VM:
