High availability VM
Hi there,
I would need a system running in a VM with high availability. My current version of KVM in Debian Lenny does not support to take snapshots of the VM while it is running. So I was wondering if I can migrate the VM and then make the snapshot on the source host. Once the snapshot is done, I would migrate the machine back to the source host. Is that possible? Can I run a savevm command on a already migrated VM?
The main idea is to make snapshots in a daily basis, and in case the host machine fails (i.e. hardware failure), starts the last snapshot in a new host.
Best regards,
Pablo

You use LVM snapshots for online backups.

For improving HA, take a look on DRBD.
