[Libguestfs] CoreOS support

Hello,

is CoreOS supported by libguestfs? 

I was trying to run several commands some were successful others ended up with
an error:
for example virt-df was OK but when I tried to do virt-resize I got the
following error message:

 root@ny2proxd03:/var/lib/vz/images/100# virt-resize --expand /dev/sda3

libguestfs *inspection* doesn't yet recognize CoreOS instances
(patches to add this would be nice), however this doesn't affect
virt-resize.

Please run virt-resize with the -v and -x options and let us know
the complete, unedited output.

Re: [Libguestfs] CoreOS support

The options -x -v gave me an error that no such option so I ruined it with
—debug option.
