Hi all, I am trying to use run_bench.py script to run checkpoints. After reading and modifying the scripts as explained in the tutorials, I could not still run it. To debug, I executed the generated command by the scripts manually and I got the following error:
" char device redirected to /dev/pts/2 QEMU 0.14.1 monitor - type 'help' for more information (qemu) qemu: warning: error while loading state for instance 0x0 of device 'ram' qemu-system-x86_64: Error -22 while loading VM state " The generated command by the run_bench.py is "/project/ouzo0/mostafa/checkpointing/marss/qemu/qemu-system-x86_64 -m 2G -serial pty -nographic -drive cache=unsafe,file=/project/ouzo0/mostafa/checkpointing/images/spec2006.qcow2 -simconfig /tmp/perl.simconfig -loadvm perl" I have checked the availability of checkpoint with "qemu-img info" " image: ../images/spec2006.qcow2 file format: qcow2 virtual size: 22G (24000000000 bytes) disk size: 6.6G cluster_size: 4096 Snapshot list: ID TAG VM SIZE DATE VM CLOCK 1 perl 216M 2013-02-26 16:36:17 00:01:17.989 " And, perl.simconfig is as follow: " -logfile /project/ouzo0/mostafa/checkpointing/marss/output_dir/perl.log -stats /project/ouzo0/mostafa/checkpointing/marss/output_dir/perl.yml -machine single_core -kill-after-run -quiet " Any help will be greatly appreciated. -- Mostafa
