It is already applied as shown from the list in the previous message
(there are some aio fixes too on top of 2.1 I picked before but they
should not impact vhost-net interaction in any mean). The symptoms are
a bit interesting - VM crashes only at PCI device initalization (e.g.
grub stage after reset and initrd unpacking are passing well, but then
things getting ugly). I am running 3.14 guest i686-pae kernel from
debian backports in guest, so it may be version-specific after all. If
it`ll be hard to reproduce, I can try 64bit, expecting same behavior.
Please find args in attached file.
