[Xen-devel] [PV] PCI passthrough and interrupt sharing


I have a setup with two NICs. One of the cards is assigned to a guest
using pcifront/back. The other one is used for host networking.

When the guest NIC's IRQ is not shared with another device, everything
works fine. When both NICs share the same IRQ, sooner or later host and
guest networking both hang.

Is this a known issue or is it supposed to work correctly?

I'm using 3.1-testing.

Kind regards
