[Xen-users] Xend not starting with pvops kernel & xen-4.0-testing build

[Nathan March <nathan@xxxxxxxxxxxxxxxxxxxx>]

Just built two servers using the xen-4.0-testing.hg branch, one using the pvops kernel contained inside, one from the pit git tree. On both of them, /usr/sbin/xend wont start. I've created the /dev/xen device nodes, I've mounted /proc/xen, nothing useful seems to get logged anywhere. I've tried configging myself as well as using the example conf off the paraops wiki page.

Can someone point out what I'm missing?
