Hi Alex,
I've been playing around with VFIO and megasas (of course).
What I did now was switching between VFIO and 'normal' operation, ie
emulated access.
megasas is happily running under VFIO, but when I do an emergency
stop like killing the Qemu session the PCI device is not properly reset.

Please don't assume this! We're trying to fix all the assumptions in
qemu at the moment.
vhost_net handles this correctly, taking bytes off
