Hi,I am trying to implement snapshot saving and loading from command line using qemu. I am using both the drive and disk options as follows.
<qemu exe> \
--disk <path to disk file> \
...other options \
-drive file=<path to drive file>, index=0,media=disk,snapshot=on,if=ide,type=drive,cache=writethrough
I am not running latest version of qemu, it is an older branch.
Some details about the issue I am facing are as follows.
As seen from info blocks command,
The disk file is mapped to virtio block device
The drive file is mapped to ide0-hd0 block device
When I savevm, qemu saves the snapshot and I can see it in the monitor console.
Also, savevm tries to modify the file provided in the --disk option rather than the one provided in -drive option (which is what I want to do).
After the above, I issue "commit".
Restarting qemu and "info snapshots" command lists only one block device = virtio
Also, no snapshots are shown.
Any pointers will be helpful.
Regards,
UE
