AW: [Xen-users] Xen 4.0.0 - tapdisk2 "hangs"

["Heiko Wundram" <modelnine@xxxxxxxxxxxxx>]

No, this update does not fix the behaviour I'm seeing with tapdisk2 (i.e.,
64-bit HVM, Multi-VCPU-domains causing the tapdisk2 process to block
indefinitely/fail), and I've also got the problem that tapdev*-devices don't
disappear after restarting a DomU.

So, I guess this is no "fix" yet. I'm still waiting for the patch spoken of
on xen-devel, which queues the requests for tapdisk2 to a single thread,
which might possibly be a fix for this (as I'm not seeing the problem on
Uni-VCPU domains).

Thanks.

Could you also start-and-destroy some domUs repeatedly (two or three
times should be enough), and see if the devices on /dev/xen/blktap-2/*
keeps on increasing instead of reusing ununsed device nodes? Just want
to make sure whether the other problem I had is specific to my
environment (distro version, config, etc.) or if it's in the kernel.
