Hi Qemu/KVM Devel Team,
i'm using qemu-kvm 0.12.3 with latest Kernel 2.6.33.3.
As backend we use open-iSCSI with dm-multipath.
Multipath is configured to queue i/o if no path is available.
If we create a failure on all paths, qemu starts to consume 100%
CPU due to i/o waits which is ok so far.
1 odd thing: The Monitor Interface is not responding any more ...
What es a really blocker is that KVM crashes with:
kvm: /usr/src/qemu-kvm-0.12.3/hw/ide/internal.h:507: bmdma_active_if:
Assertion `bmdma->unit != (uint8_t)-1' failed.
after the multipath has reestablisched at least one path.
Any ideas? I remember this was working with earlier kernel/kvm/qemu
versions.
Thanks,
Peter
