Ugh. Spoke a little too soon. While I got past my problem creating a =
storage domain, I ran into a new sanlock issue.
When trying to run a VM (the first one so I can create a template), I =
get an error in the admin UI:
VM DCC4.0 is down. Exit message: Failed to acquire lock: Permission =
denied.
The sanlock.log file shows the following:

I looked at the lease file referenced above, and it is there.

On a lark, I turned off selinux enforcement and tried it again. It =
worked just fine.
So what selinux option do I need to enable to get it to work? The only =
other sanlock specific settings I saw are:
sanlock_use_fusefs --> off
sanlock_use_nfs --> on
sanlock_use_samba --> off
Do I turn these all on or is there some other setting I need to enable?
