I have a clean install of trusty on an intel laptop. I added the following upstart job in the forhallyn-trusty-amd64.img root partition:
#################################################################### description "update and shutdown" author "Serge Hallyn <[email protected]>" start on runlevel [2345] script sleep 5s apt-get update DEBIAN_FRONTEND='noninteractive' apt-get -y dist-upgrade sleep 5s shutdown -h now end script #################################################################### Then on the host I run this script: #################################################################### #!/bin/bash cp orig-with-upstart/forhallyn-trusty-amd64.img . virsh snapshot-create-as forhallyn-trusty-amd64 pristine "uvt snapshot" virsh start forhallyn-trusty-amd64 sleep 20s while [ 1 ]; do virsh list | grep -q forhallyn || break sleep 20s done # guest has updated. check the image file and fs here qemu-img check forhallyn-trusty-amd64.img if [ $? -ne 0 ]; then echo "image check failed after shutdown" exit 1 fi qemu-nbd -c /dev/nbd0 forhallyn-trusty-amd64.img fsck -a /dev/nbd0p1 if [ $? -ne 0 ]; then echo "fs bad after shutdown" qemu-nbd -d /dev/nbd0 exit 1 fi qemu-nbd -d /dev/nbd0 # now tweak the snapshots virsh snapshot-delete forhallyn-trusty-amd64 pristine --children virsh snapshot-create-as forhallyn-trusty-amd64 pristine "uvt snapshot" # and check the image file and fs again qemu-img check forhallyn-trusty-amd64.img if [ $? -ne 0 ]; then echo "image check failed after snapshot remove/create" exit 1 fi qemu-nbd -c /dev/nbd0 forhallyn-trusty-amd64.img fsck -a /dev/nbd0p1 if [ $? -ne 0 ]; then echo "fs bad after snapshot remove/create" qemu-nbd -d /dev/nbd0 exit 1 fi qemu-nbd -d /dev/nbd0 # all seems well exit 0 #################################################################### I'll run that in a loop and see if it fails after 10 tries. If you see anything there that I am NOT doing which would help to reproduce, please let me know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1292234 Title: qcow2 image corruption in trusty (qemu 1.7 and 2.0 candidate) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1292234/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
