[Xen-users] p2v migration + Xen

["Dan Hawker" <danhawker@xxxxxxxxxxxxxxx>]

Hi All,

We are using Xen to help keep certain services separate on the LAN but
also to create multiple virtual machines for safe and easy software
development across multiple platforms (all Linux based).

Am looking for some advice/tips/how-tos/whatever to help in a p2v
migration I am about to undertake.

We have a machine in place that I would like to migrate, however am unsure
as to what the best option would be. I am not going to get much time for
the machine in question to be *not available*, so wondered if I could use
rsync or similar to create a backup of the filesystem in question directly
into a directory structure on the new server for the resultant Xen VM. I
could do this whilst all things are still live. At the moment we'd like to
swap over, we could then do a quick and final rsync, turn off the original
server and bring the Xen VM up.

Does this make sense??? I presume there will be some directories and files
that shouldn't be migrated (/dev, /tmp, etc) which files/dirs are safe to
leave behind???

The reason I'd like to move the server over, rather than install a new VM
and update it, is because as mentioned its a software dev box and has been
here a while, (before I arrived). Hence I am unsure as to what packages
and apps have been installed and how.

TIA

Dan
