Server is CentOS 5.2, client is fedora 9.  Virt-manager version is
0.5.4 binary RPM from the Fedora repo. The server was Fedora 9 but I
installed CentOS 5.2 on it today and it's using the Xen kernel now and
having the same trouble.  Again, locally, virt-manager works
fantastically, but when I try to connect remotely it gives me trouble.
 I don't know how it could possibly matter, but I'm connecting back to
another location using vpnc and then opening virt-manager, so I've got
maybe 150ms latency to the libvirtd host.

I've been launching virt-manager from Applications -> System Tools ->
Virtual Machine Manager.  Also I've launched it a few times with
something similar to: $virt-manager -c xen+ssh://10.2.30.12/system.
Now I've also tried: $virt-manager --no-fork -c
xen+ssh://10.2.30.12/system (no password prompt by the way). It seems
to be logging in because, like I said, if I stop libvirtd, I get a
list of the available guests on the libvirtd server.  And actually
once I connect if I wait 15 or 20 minutes it will return a list.  It
will just freeze up intermittently and it's never responsive to input.
 If I try to click on a guest to select it, it will take 2 or 3
minutes before the selection takes effect and the item is highlighted.
