Hi howard chen,
If I rsync the following folders from one guest to another guest for
complete system migration, is it safe?
...
p.s. I cannot use live migration or other tools since I don't have
control to the host. I can only control the guest.
worst option - online:
It's possible, but you will not get consistent data.
better option - lvm:
Install LVM on both guests, create a snapshot of src-guest and copy the
data to dst-guest.
Pro: + consistent data (ok, maybe you should shutdown dbs..)
Con: - you will loose every change between snapshot-creation and
transfer-finished.
best option - offline:
I would shutdown both guests and start the sync (may you can boot a
rescue-system?)
Maybe it helps,
Fabian
