Re: [libvirt] [PATCH 0/2] qemu: Cancel/forbid migration on I/O error

When qemu has paused itself due to a I/O error it's not safe to
migrate it
as it still might contain state in kernel buffers. These patches forbid and
cancel ongoing migration if a I/O error happens.

qemu: Forbid migration of machines with I/O errors

This actually should be supported, it certainly is in QEMU. What kind
of state is in the kernel and what is the BZ for this patch?
When a system call returns, it should be all done.
