Here's relevant snippets from my cluster.conf:

<cman expected_votes="10">
</cman>

<clusternode name="xen1.msp.technicality.org" votes="50">
</clusternode>

<clusternode name="xen2.msp.technicality.org" votes="50">
</clusternode>

<clusternode name="xen-vm-1.msp.technicality.org" votes="1">
</clusternode>

I can bring xen1 or xen2 online without any other nodes online, and get 
quorum. Once both nodes are online, though, cman_tool status says:

Nodes: 2
Expected_votes: 10
Total_votes: 100
Quorum: 51

..so the quorum value is being raised to 51, which is half+1 of 
Total_votes, not the Expected_votes (which would be what I'd expect, but 
again, I'm a newbie.) What I'd really like is a way to lock the quorum 
number down to 10 (at all times), so if any physical node is surviving the 
cluster will be up. Is there any simple way to do that?
