Since Qemu-0.13 version they have changed default disk cache settings so creating checkpoint and loading checkpoint with default parameters take too long. You have to use 'cache=unsafe' option to create checkpoints faster. I have just pushed few fixes to 'qemu-0.14' and 'core-models' that will make sure that checkpoint is created correctly when using 'cache=unsafe' option.
new command : $ qemu/qemu-system-x86_64 -drive file=/your/qcow2/image,cache=unsafe Also when you load the checkpoint use the same 'cache' option. - Avadh On Mon, Jun 27, 2011 at 1:25 PM, Ishwar Singh Bhati <[email protected]> wrote: > Hi All,**** > > ** ** > > Is anybody using the “qemu-0.14” branch of marss with checkpoints? **** > > ** ** > > I am calling the function “ptlcall_checkpoint_and_shutdown(str_checkname)” > at the region of interest of my benchmark to get the checkpoint.**** > > This works well in master branch, but it takes either very long time (~12 > hours) or never finishes checkpointing in qemu-0.14 branch.**** > > Did somebody find any reason/solution for this?**** > > ** ** > > Thanks**** > > Ishwar**** >
