Title:
virtio-pci: can't reserve io 0x0000-0x001f
Status in QEMU:
New
Bug description:
Before 2012-03-05 I was able to successfully enable a virtio-pci block
device from a sPAPR pseries ppc64 Linux guest. With the current git
master branch after this date I get the following error:
virtio-pci 0000:00:00.0: device not available (can't reserve [io
0x0000-0x001f])
virtio-pci: probe of 0000:00:00.0 failed with error -22
virtio-pci 0000:00:01.0: device not available (can't reserve [io
0x0000-0x003f])
virtio-pci: probe of 0000:00:01.0 failed with error -22
