Re: [Linux-cluster] VM migration

Are you using shared storage? Is far as I know, the current cluster suite wont do an automatic live migration to another server during a reboot, but it will do the live migration back after the reboot. Does that make sense?

Subject: [Linux-cluster] VM migration




I am running a cluster having 2 nodes using red hat cluster suite in CentOS 5.2. node 1 has a para virtualized guest(centOS)  running under Xen. My question is when node1 is rebooted, guest is automatically relocated to node 2 . Instead of relocation, is migration possible in this case which can result in Zero down time?



Thanks in adv

Exactly as you said. It is relocating and as soon as the original node comes back it is migrated automatically.

Yes I am using shared storage using SAN/GFS2. Any workaround on this to make migration possible inserted of relocation
