Hi,
I've just come across a somewhat strange problem that was suggested I
report to the list.
The problem manifested itself as DMA errors and the like popping up in the
guest, like I'd expect to see if a disk in a physical machine was dying,
like this:
hda: dma_timer_expiry: dma status == 0x21
[...]
I've seen a similar effect on my KVM host server. There were I/O errors
on one partition. When I tried to reformat the partition and restore its
content from backups, mkfs was reporting I/O errors, always at the same
block number. I added a second qcow2 file and moved the partition there.
It's worth trying a qemu-img convert to move the image to an LVM volume.

I have a truly marvellous patch that fixes the bug which this
