Hi all,

Suppose tapdisk2(a) serves Dom1, tapdisk2(b) serves Dom2, when both
Dom1 and Dom2 are issuing random write requests, is it possible for
tapdisk2(a) to dispatch requests both from Dom1 and Dom2? I hope not,
but when I trace the I/O in Dom0, I notice that tapdisk2(a) dispatches
requests from both guest domains. Is it common? I thought each
tapdisk2 should only dispatch requests from its own DomU.

Any comments are appreciated!

Thanks,
Yuehai
