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,
Lu=C3=ADs
