I understood what was said by the way about the permissions. I temporarily switched off SElinux. I think I just may not be entering the command correctly. If I put home/testa/image.dump I get Could not open 'image.dump' If I put /home/testa/image.dump I get Invalid char in expression from the first slash. Can someone who has gotten this to work please tell me how they typed out the entire command in full detail? I don't really care where it saves it, I just need the dump of the memory.
If qemu is running under non-root user I wouldn't expect it to be able to access $HOME.
I have tried this with various forms of the path:
sudo virsh qemu-monitor-command --hmp Shawn 'pmemsave 0 536870912 image.dump'
Although I must admit this doesn't play nice. I can get two different results: virsh # qemu-monitor-command --hmp f16 "pmemsave 0 1024 /tmp/dummy.img" invalid char in expression virsh # qemu-monitor-command f16 '{"execute":"pmemsave", "arguments": {"val":0, "size":1024, "filename":"/tmp/dummy.img"}}' {"return":{},"id":"libvirt-12"} In the latter case image is successfully created. But I am not sure whose bug is it - libvirt or qemu. Michal
