Re: [virt-tools-list] restoring backup from an LVM Guest OS on KVM Lucid

Yes Justin that does help.
I need one more information.
When I used virt-manager had installed the guest OS in and LVM.
The process of creating a ext4 and swap in that LVM was taken care by virt-manager.
How does virt-manager do that?
Suppose I take an rsync backup of the filesystem on LVM.(Swap wont be backed up in fact it is not needed)
Then on the other server if I want to use this rsync backup i.e. want to boot from the os whose backup was
taken is how is that done? Does this also comes under migration?
How does virt-manager handles the process of creating a file system and swap co existing
in same LVM.Is it possible to reproduce this manually then how can I do that?

Let us call this server A
I am running another server where KVM is running call this server B.
Is is some how possible guest running on server A can be transferred to B
so that I can run it and do not have to do any extra work.

Hi Tapas,

You're looking for what's called "Migration", where you transfer guests
between hosts.

This works quite well, *but* you have to set things up for it before

The guest image files need to be running in a shared storage location,
that both "server A" and "server B" have access to.  For example, using

As you're using Ubuntu, the Ubuntu wiki may have info (I haven't
checked), and the HowtoForge.com might be useful too:


As a thought for the future, I'm presently creating documentation for
areas like this that need to be done better, but haven't gotten up to
the migration stuff yet.

Does that help?

Regards and best wishes,
