Interesting... The same sequence with virtual IDE-disks on same guest does not generate any errors. Thanks for the report Alexander. Possibly fixed by:

scsi: avoid assertion failure on VERIFY command
A verify command is not an actual read (we do not implement
compare mode) and thus does not have an AIOCB attached. Do
not crash in scsi_dma_complete.

qemu-1.4.2-8.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/qemu-1.4.2-8.fc19 Package qemu-1.4.2-8.fc19: * should fix your issue, * was pushed to the Fedora 19 testing repository, * should be available at your local mirror within two days. Update it with: # su -c 'yum update --enablerepo=updates-testing qemu-1.4.2-8.fc19' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-15760/qemu-1.4.2-8.fc19 then log in and leave karma (feedback). qemu-1.4.2-9.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/qemu-1.4.2-9.fc19 Sorry, guys! Just installed qemu-1.4.2-9.fc19 and got same problem... On disk checking (free space checking stage) qemu was crashed. Thanks for checking Alexander. Can you attach /var/log/libvirt/qemu/$vmname.log? Another thing to check is enable the fedora-virt-preview repo, update qemu, and see if you can still reproduce, that has qemu 1.6 in it. Undoing is as simple as 'yum downgrade qemu\*' to revert to F19 packages. http://fedoraproject.org/wiki/Virtualization_Preview_Repository Created attachment 794547 [details]

And I don't know how and what manually upload after new crashtest. Sounds like a straightforward reproducer with qemu 1.6 + windows + virtio-scsi + 'chkdsk c: /x /f /v /r' inside the VM. I'll reassign to virtio-win but might be a qemu issue Thanks for the report, I'll try to reproduce. (In reply to Cole Robinson from comment #24) > Sounds like a straightforward reproducer with qemu 1.6 + windows + > virtio-scsi + 'chkdsk c: /x /f /v /r' inside the VM. I'll reassign to > virtio-win but might be a qemu issue I just tried two times for the Win2k8 R2 guest on the rhel6.5 host and rhel7.0 with the same steps as comment 1001617#c21 using the same virtio-win-prewhql-0.1-74 driver version, It worked well on rhel6.5 host, but met this issue on rhel7.0 host which QEMU aborted. I think it's QEMU issue as the same virtio-win driver version just different qemu-kvm version. host info: - rhel6.5 host. 3.10.0-55.el7.x86_64 qemu-kvm-rhev-1.5.3-19.el7.x86_64 seabios-bin-1.7.2.2-4.el7.noarch - rhel7.0 host. host info: 3.10.0-55.el7.x86_64 qemu-kvm-rhev-1.5.3-19.el7.x86_64 seabios-bin-1.7.2.2-4.el7.noarch guest info: Win2k8 R2 64bit virtio-win-prewhql-0.1-74 Steps: same to bug 1001617#c21. Results: QEMU will aborted on rhel7 host after reboot windows guest for start checking, But it worked well on rhel6.5 guest, both two times of testing can pass successfully.
