Overall, the Ceph GUI is great. I actually got Ceph up and running

an obvious way to simplify things... for small clusters, anyway.
I am seeing some problems, however, and I'm not sure if they're just
me, or if I should be opening bugs:
1. I have one node that's up and running just fine, pvecm claims
everything's fine, but I can't migrate VMs that started somewhere else
to it - migration always fails, claiming the node is dead. Nothing
unusual appears in any logfile that I can see... or at least nothing
that looks bad to me. I can create a new VM there, migrate it
(online) to another node and migrate it back (online, again), but VMs
that were started on another node won't migrate.
5. Stopping VMs with HA enabled is now an *extremely* slow process...
If I disable HA for a particular VM, I now notice that Stopping also
produces a Shutdown task, and it takes longer than previously, but not
unreasonably slow. I don't understand why Stop isn't instantaneous,
though. I notice that typing "stop" into a qm monitor also is slow...
the only way I have to rapidly stop a VM is to kill the KVM process
running it.
FYI: Completely shutting down all four nodes (note: the last two refused
to shutdown cleanly, I had to remove power) and rebooting them seems to
have solved both these problems.
