Thanks for your help.
But, after commenting out snapshot option, I still cannot save the VM state
into the ide0-hd0 block device.
Here is some more information about the problem.
I am trying to do the following
a. info block
shows virtio, ide0-hd0
b. savevm snapshot_name
c. info snapshots
Shows snapshot_name under virtio
d. commit ide0-hd0
e. quit
f. Check timestamp of ide0 file - no change. ( I assume that qemu would
write something to this file)
g. restart qemu.
h. info snapshots
i. No snapshots in "virtio"
I will try to run qemu in gdb mode to see why commit is not committing the
changes to the ide0-hd0 block device.
But any other information will be helpful as well. I have googled a lot
without much luck.
Regards
UE.
