Nack.
You can simply "fix" a COLO issue by breaking a much more common usecase.
Yes, this patch is wr
for the --set-mark argument to have value equal '1' , not a hex?
This log is very useful, we will investigate it.

It is implemented by Yang one year ago. I don't know the reason. We will

I don't know how to work with PV block backend. It is one reason that
why we only support pure HVM now.
For PV block backend, there is also other problem. For exampe resuming
it in the secondary side is very slow, because we need to disconnect and
reconnect.
