Failed snapshot removal

[isodude]

Hi,

Using Ceph and Proxmox VE, removing a VMs snapshot with memory snapshot enabled, it fails miserably. A normal snapshot without memory snapshot works splendidly.

The error in the end sounds scary, does it try to remove the base image?

Cheers,
Josef

Hi,
I got the same issue. I get this error when trying to remove snapshot with included RAM. However, I can remove it after I shutdown the snapshoted vm. It is somekind of workaround, but not for production environments. Is there any other fix for it ?

Hi,
I submitted this as a bug in proxmox bugzilla. https://bugzilla.proxmox.com/show_bug.cgi?id=553
However, I am not sure if it is in a correct component section.

Kind regards,
Piotr D
