Xen 4.6.1 breaks PCI attachment #2038

andrewdavidwong · May 29, 2016

with Xen 4.6.1-15.fc20 (which got recently uploaded to the testing repo)
VMs with attached PCI devices don't boot anymore (at least on my
machine).

When I try to boot a VM with attached PCI devices it crashes
immediately. Attached the xen dmesg log of a crash.

Both dom0 and the VM are running the 4.1.24-9.pvops.qubes kernel.

xen-4.6.1-vm-crash.log:

HW42 (post):

This is not really related [to #1659]. My problem is PV related (didn't tested
HVM). And most notably this is a direct regression of the update to xen 4.6.1-15.fc20. xen 4.6.0-13.fc20 works fine.

Closing this since the discussion is taking place in the original thread.
