You can dd a block device into an image and/or another block device, even
possible over ssh/network.
An lvm volume is a block device.
You can mount filesystems (from partitons or block devices or files, as linux
can create an fs onto a lots of things), and not "disks".
What you basically do with proxmox is you create an lvm volume and pass it to a
VM as a disk (block device). Then you partition theese inside the VM.
Hope it helps.

Sorry but how should I do a backup when the host doesn't work correctly?
Or like this:
with dd make an image file from the volume:
dd if=/dev/dm-6 of=/root/vm-100-disk-1 bs=1M
Then move the file to the new host and play it on the new host back?
