Every now and then I get reports of a customer's DomU running slowly and,
sure enough, when I connect it takes ages to login. However, it's running
at 100% idle and the other DomU on the same box is fine. A reboot of the
DomU fixes it. When it happened today, I saw the following on the Dom0
console (which is running quickly and responsively):
xvif3.0: can't map packet page
The first two are debugging, I believe, but the third looks suspicious...
The kernels are 3.1_STABLE from 20th Nov 2006. Have there been pullups
that fix this, i.e. should I be updating? I'm not in a position to upgrade
to NetBSD 4.0/Xen3 at the moment.
