Hi,

I'm having debian etch server,in which i'm running xen machines using LVM based.

Now i'm provided with debian Lenny server. what i need to do is, i want to migrate all xen domains from debian etch server to debian Lenny. Live migration is not needed,even i'm happy if it is possible to take the backup of the domain and start over there(Lenny server).

I dono how to backup the xen domain and how the images are, please help me in this migration operation.

Thanks in Advance!

The images should be stored where you declared them to be stored. I use CentOS so might be some differences but the image configuration files should be stored at /etc/xen/ and in them you can find out where the images are stored by looking at the disk value, it won't be the only thing on the line but I assume you should be able to figure it out from what appears their.

Hi
Thnaks for ur reply.

my /etc/xen/xenmachine.cfg file looks like this

# Disk device(s).
#
root = '/dev/xvda2 ro'
disk = [
'phy:/dev/private_cloud/c4-swap,xvda1,w',
'phy:/dev/private_cloud/c4-disk,xvda2,w',
]
my VM's are running under the LVM's.

Can u pl tell how to backup the machine and restore the same in different machine.

Thanks in Advance!

you are using lvm on local machine.
You can migrate the disks from the machine and put it in the new machine
do a vgchange -a y to get the LVM enabled and use the same config file.
The Xen is transparent to the underlying LVM partitions.

if you want to backup and restore ... you have to dump the whole of the LVM partition
using dd or similar command and create the partition again in a new machine (same size or more)
dump back the backup and do all extend operations - check validity of PVs VGs and LVs and
enable then by vgchange -> if this is what you meant by backup up and restore from one machine to
other.
