[virt-tools-list] Creating memory file on disk

[Echo6]

Hi!

I have a need to store a copy of the virtual machines memory in a file on disk, ideally during a snapshot or pause.

According to the qemu manpage, this may be possible using -mem-path options

-mem-path path
           Allocate guest RAM from a temporarily created file in path.

Is it possible to enable this option using virt-manager? I assume it is, but how?

Jon.
