I had an ubuntu9.10 KVM using virtio to talk to a qcow2 image file. One day I was trying to backup the file to a usb drive with rsync -a -S and I could never get the checksums to match (yes the virtual machine was shut down :-).
I then tried backing it up to a different name in the same directory with the same result, no checksum match. I then ran fsck on the drive (forcing it to check) - no problems found :-). Has anyone ever seen anything like this before? Can qcow2 map disk pages to /dev/random? :-). Eventually, I tried booting up one of the copies I made (which could be backed up with good checksum matches), found that the booted machine seemed to behave normally using the copy, and just removed the funny image file that would never copy. _______________________________________________ virt mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/virt
