Hello,

I am attempting to snapshot a stopped Virtual Machine. The VM is Windows XP and is powered off during this attempt. The "Take Snapshot" button in the web gui is grayed out in the "Snapshots" tab. I also attempted to snapshot the VM through the cli and received the following error.

Code:
root@proxmox:~# qm snapshot 105 test
snapshot feature is not available at /usr/share/perl5/PVE/QemuServer.pm line 4353.

root@proxmox:~# qm config 105
args: -vnc 0.0.0.0:5
bootdisk: ide0
cores: 1
ide0: container_storage:vm-105-disk-1,size=40G
ide2: cdrom,media=cdrom
memory: 1024
name: winxp-victim
net0: e1000=B6:4F:50:E0:1C:02,bridge=vmbr1
ostype: wxp
sockets: 1

I believe the problem here is that I am using LVM as storage for my disk images. There is no content drop-down menu when editing the LVM group "container_storage".

Is there any way around this? The LVM information is below.

Code:
