[Xen-devel] Tapdisk2 problem

[Luís Silva <luis.silva@xxxxxxxxxxxxx>]

Hello,

I'm using both xen 4.0.1-rc5 and the latest pv_ops dom0 kernel (branch xen/stable-2.6.32.x), but I'm having some problems with tapdisk2...

Basically, if I create a tap device (tapdisk2 -n aio:/var/lib/libvirt/images/srv-001-ub1004.img), when I try to terminate it by issuing "echo 1 > /sys/class/blktap2/blktap0/remove", the last command hangs and tapdisk2 hangs using 100% cpu.

This happens both on manual device destruction and on virtual machine shutdown. I don't know exactly what triggered this behaviour, but I suspect kernel changes.

Can anyone confirm this behaviour?

Thanks,
Luís
