Re: [Xen-users] p2v migration + Xen

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???
If you're not using udev, you'll want to migrate /dev over. /tmp is also
fine.
I usually just exclude /proc and /sys.
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.
Sounds quite reasonable to me. It's similar to how I do it..
