Hi,

I see the below error when i change the memory.

virsh save-image-edit /MANAS/rhel7VM1-running-save2 --running
error: unsupported configuration: Target domain max memory 4194304
does not match source 2097152
Failed. Try again? [y,n,f,?]: n
error: unsupported configuration: Target domain max memory 4194304
does not match source 2097152

Any idea why is this disallowed ?

Thanks,
Shiva
