Hi, I am running a cluster having 2 nodes using red hat cluster suite. 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 Paras. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.centos.org/pipermail/centos-virt/attachments/20080829/751406a0/a...

Not so much a CentOS-virt question. More of a Red Hat Cluster question. jerry -- There's plenty of youth in America - it's time we find the "fountain of smart".

If you're using the xendomains init script, you can set XENDOMAINS_MIGRATE in /etc/sysconfig/xendomains. -- Christopher G. Stach II

Still relocation is going on instead of migration. Thanks Paras. -------------- next part -------------- An HTML attachment was scrubbed...
