I think the tricky part here is that the lvm volume may contain multiple
partitions (I think it does have a / and a swap since it's a virtual
machine disk), and I need the partition information, including the boot

Yes it is local network, same rack, I even have a private subnet between
the machines.

This seems to be the foolproof way

Was just hoping I could figure out how to do it faster, clonezilla seems
fancier than just partclone though. I think I need something that dumps
the partition information too.
