Only 1 active guest (the FreeBSD one) - there are others on there, but=20 they're not running (so I'm hoping they don't count? :) > I don't think those modifications have any effect on the timer, but > could you try to recompile without the NO_ADAPTIE_* modifications and > without any device pass-through? Removed the NO_ADAPTIVE_ stuff from the Kernel - I'll have to do the PCI=20 passthrough removes later. > In order to provide more debug info, could you apply the following patch: > > http://xenbits.xen.org/people/royger/0001-xen-debug-Xen-PV-timer.patch > > It will expand the panic message a little bit.

Ok, with that patch applied, removing the NO_ADAPTIVE_* (but like I said -=20 still with the PCI passthroughs in place) I get: " panic: can't schedule timer on vCPU#0, interval: 112847ns " I'll increase NUM_TRIES, try that - then remove the PCI passthrough devices = and give that ago - that'll have to do those in a bit, and post when done. Thanks, -Karl
