[libvirt-users] qemu-monitor-command

[Shawn Davis]

Hello Everyone,

 

I am working on a grad school project for virtual introspection.  I have a
vm running (with 512mb of memory) and want to access the pmemsave function
through virsh with the qemu-monitor-command.  I am typing the following:

 

virsh qemu-monitor-command --hmp Shawn 'pmemsave 0 536870912 image.dump'

 

Shawn is the name of my vm and image.dump is the name of my output file.  No
matter what I do, I keep getting: Could not open 'image.dump'  

 

I have tried the above with sudo and with the absolute path of where the
newly created dump file should go and I still get that error.  Any help is
appreciated as to how I should enter this command.

 

If I type in virsh qemu-monitor-command --hmp Shawn 'info mem' or any other
command without an output path, it works fine and brings up information
about my running vm.

 

Regards,

Shawn
