Comparing HA-Lizard and XenServer HA
-
And that is only the Snapshot portion, migrating it off host obviously takes a bit of time.

Sure, but other than using some resources shouldn't really be noticed by the VMs themselves.
-
@DustinB3403 After the snapshots are complete, the VMs should go back to running.
-
@dafyre Correct they do.
Immediately after those first few seconds. The data transfer off host takes the longest amount of time to complete.
I have 4 VM's that we backup (care about) that use 696GB of data, so the transfer time takes a bit.
-
@DustinB3403 How much does that affect the performance of the VMs that are running while your backups are being copied off?
-
I've never monitored them.
The work is being done by Dom0, not the VM.
And with the resources being statically assigned I can't imagine that there is much of a hit to the performance of the VM's them self.
