With virtio-blk dataplane, I/O errors might occur while QEMU is
not in the main I/O thread. This makes the block layer's
bdrv_error_action() function thread-safe (modulo changes in
the monitor to make QMP events thread-safe too, already posted).
Thanks to Kevin for discussing v1, the ideas are based on his
input too.
v1->v2: redone, v1 should really have been an RFC
Paolo Bonzini (2):
vl: allow other threads to do qemu_system_vmstop_request
block: asynchronously stop the VM on I/O errors
