Hi, this mini-series is a spin-off of my ITS emulation series, so those patches have been on the list before [1]. I repost them separately here to get them merged, because patch 2/3 fixes a real issue: Vhost-net support seems to be broken (on x86). In my experiments (-n mode=tap,script=/etc/qemu-ifup,vhost=1) the guest hangs because it waits for an virtio IRQ to trigger. But the MSI never makes it through, because virtio-pci changes the MSI configuration _after_ having set up the IRQ routing for this interrupt. So we need to update the IRQ routing in case PCI config space accesses change the MSIs. I put the move of the IRQ routing code into generic code here as 1/3, since we need this anyway later and swapping the two patches looks like pain, which we would also need to redo later anyway. Also it should help to consolidate other IRQ related patches. Finally we deny vhost-net on any bi-endian architecture at the moment, which is unnecessary as long as host and guest use the same endianess. Patch 3/3 fixes this. Please have a look and apply! Cheers, Andre.
