No problem. I was just making sure that you should get attention
from the right crowd.

Not sure if I follow. Why would you run heartbeat in one VM and
web server in another?

Basically, you have two options: run cluster within the VMs, it
would then manage web server and such, or manage whole VMs on the
hosts using the Xen RA (or vmware).

for the passphrase for the certificate.

Probably, but test it thoroughly. Just make sure that your files
are consistent with the database, if that's possible.
