It would have been nice if you had tested (for the test only), one physichal machine with FreeBSD doing nat and the other three vm under Xen with FreeBSD, to see if problem persists...this way we could figure now if the problem was something to do with Xen or with the own FreeBSD configuration... although I assume the problem is in the last one... So far it was the only problem I had with FreeBSD and Xen Cloud Platform. My FreeBSD VMs are serving nginx + rails and python apps, PostgreSQL and MySQL databases, and the perf is good for now. VMs disks are LVM partitions of XenCloud, not files. Hope this helps. Of course!! Thanks a lot mate, Good bye!

I've been using FreeBSD on Citrix Xenserver with FreeBSD 8.[012] for a year now; in HVM mode. The only issue, other than the lack of support for xentools, is that in the earlier 8.x I had to manually set kern.hz low or the clock would eat too much CPU time in the VM (IIR, this was fixed in 8.2). I haven't had an opportunity to try FreeBSD as a PVM. -- Perfection is just a word I use occasionally with mustard. --Atom Powers-- Director of IT DigiPen Institute of Technology +1 (425) 895-4443 ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
