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.
