Hi,
Would you please help explain in which case AioHandler->is_external is true, and
when it is false?
I read about iothread and mainloop and I am little bit confused about it.
Thank you very much!
Dongli Zhang
Ping?
Thanks!

It looks the kernel space vhost-blk can only process raw image.
How about to verify that only raw image is used in the drive command line when
vhost-blk-pci is paired with it?
Otherwise, vhost-blk-pci might be working with qcow2 image without any warning
on qemu side.

In virtio_blk_handle_request(), in_iov is used for input header while iov
is used for output header. Rename iov to out_iov to pair output header's
name with in_iov to avoid confusing people when reading source code.
