Betreff: [Xen-users] pci-attach on dom0 kernel versions above 3.8 crashes dom0
I'm still having trouble getting passthrough to work on kernels above 3.8.
Currently I'm trying with kernel 3.11 to passthrough a intel X520 using ixgbevf.
Attached kernel messages from both xen, dom0 and domU - please let me know if more is needed.
Basically what happens is this:
dom0# xl pci-attach vm1 '0000:01:12.3,permissive=1'

Any help is greatly appreciated.
