Re: [Linux-cluster] linux cluster and virtualization - shared xend-config.sxp



Aaron,

The documentation provided via the conga cluster recipe (Add a virtual machine as a clustered service <http://sourceware.org/cluster/conga/cookbook/VMs_as_services>) states that:

1) "Both xen config files [e.g. xend-config-sxp] and VM disk images must be located on shared storage, with identical mount paths for each node"

and then on the next slide states:

2) "Xend must be running on each node, and MUST BE STARTED BEFORE THE CMAN CLUSTER DAEMON"

> ...

The only other documentation I found for this setup: http://magazine.redhat.com/2007/08/23/automated-failover-and-recovery-of-virtualized-guests-in-advanced-platform/ says absolutely nothing about system service startup order and includes an example of a cluster node reboot.

So, my question is this; is the default ordering of system service startup (cman < xend) workable with virtual machines defined as cluster services?

It works fine in the normal startup order. xend has to be started before rgmanager and after cman.

best regards, Gunther
