Can youshow a proper testcase without that guestfish stuff? The full command I ran is listed right there in the build log
I linked to.

Hello, I've hit this on RHEL6.2-20110812.n.0 (guest) running on RHEL6.1 GA (host). My command is: qemu-kvm -monitor stdio -m 1024 -net tap -net nic,model=virtio -drive if=virtio,file=/srv/images/system1,boot=on -cdrom boot.iso -boot once=d And both systems were x86_64. Pavel, do these errors cause problems? For me, the guest appears to continue running regardless. There doesn't *appear* to be any actual disk corruption or stoppage, although the messages in 'dmesg' certainly look worrying. Can't see any real problem too, both systems seems to run fine for me. I have reproduced this issue with 2.6.32-131.21.1.el6.x86_64, qemu-kvm-0.12.1.2-2.160.el6_1.9.x86_64, lots of "block I/O error in device 'virtio0': Input/output error (5)" pops up when trying to boot a virtio-blk-pci image, but these errors seems wouldn't cause any corruption. Adding werror=stop to same cli, guest won't stop on block I/O error. But guest will stop on block I/O error if appending * rerror=stop* to same cli. So, it is a read error from this point of view. Hope this helps. Additional info: Can't reproduce this issue on rhel6.2 with same cli with 2.6.32-216.el6.x86_64, qemu-kvm-0.12.1.2-2.209.el6.x86_64 chayang, Then, could you close this bug?
