[Qemu-devel] question about concurrent block job

[Zhangleiqiang]

Hi, Paolo:
        I found qemu does not support concurrently running multiple block jobs 
of the same drive (limited by the bs->in_use field).  But there are indeed some 
type of block job can run concurrently, such as running block stream job while 
running drive mirror, etc.  Am I right ? Is it necessary to introduce the 
concurrency mechanism in qemu ?

        Thanks.
