Assuming this is the same patch that I posted on the list after someone
sent it to me, it seems to solve the problem (xn* works).

I have several VMs running with it for around 3 weeks now, no problem
whatsoever in that area.

A major problem (and after the netdiff fix, the only one that comes to
mind in FreeBSD/Xen, from a SA PoV) right now is the VMs losing massive
amounts of time (just the other day I manually ran ntpdate, for a 1h
adjustment); started a thread last week or so, but it died down.

It may not happen 100% of the time (calcru: runtime went backwards +
losing system time), as I remember that a couple of years ago several
people on the list had this problem while I wasn't experiencing it.

Perhaps it depends on the dom0 OS, some system hardware.. I really have
no idea..

If someone else is running amd64 HVM+PV, let us know if you see the same?
