Re: [Xen-users] VMware guests to xen
If you are migrating generally Linux boxes, I'd just create the xen
virtual machines, and then use rsnapshot to migrate them as a backup of
the live system. I'm assuming that you are doing this on different
hardware. I can tell you that this is a very clean way of doing it
without trying to figure out file system differences etc.
Rsnapshot is a backup solution based on rsync and perl and does not
require any special libraries or anything. I recently migrated a LAN
server from a standalone box, by setting up rsnapshot and a cron to run
it nightly to the live xen machine in a backup location. Once I was
ready to move it live, I simply moved the directories from their backup
locations to the live location, unplugged the network cable of the old
box, and fired up the new virtual machine. It was flawless and it took
very little personal time to do.
If this sounds like something you'd like to try, feel free to contact me
off list. I'm actually getting ready to do exactly this with an old
machine running vmware to a new xen setup with 3 virtual servers on the
vmware machine.
Thanks,
