[Xen-devel] [PATCH 2/2] libxl: clean up qemu-save and qemu-resume files

[Wei Liu <wei.liu2@xxxxxxxxxx>]

These files are leaked when using qemu-trad stubdom.  They are
intermediate files created by libxc. Unfortunately they don't fit well
in our userdata scheme. Clean them up after we destroy guest, we're
sure they are not useful anymore at that point.
