Hi Kevin,
here we go. I created a blocking multipath device (interrupted all
paths). qemu-kvm hangs with 100% cpu.
also monitor is not responding.
If I restore at least one path, the vm is continueing.

hi kevin,
you did it *g*
looks promising. applied this patched and was not able to reproduce yet :-)
secure way to reproduce was to shut down all multipath paths, then
initiate i/o
in the vm (e.g. start an application). of course, everything hangs at
this point.
after reenabling one path, v

hi kevin,
i set a breakpint at bmdma_active_if. the first 2 breaks encountered
when the last path in the multipath
failed, but the assertion was not true.
when i kicked one path back in the breakpoint was reached again, this
time leading to an assert.
the stacktrace is from the point shortly
