Hi!

I was trying to start 30 virtual machines as a final stress test for
my Xen server but it fails like this for the 24th domU. I've increased
kern.maxfiles to 500000 but it's still failing. Any ideas?

I think the last (30th) domU failure is okay because I'm running out
of memory (this machine has 4 GB) but 24th - 29th I don't understand...
