[Libguestfs] libguestfs mounting solaris 10 ZFS guest

[John Larson]

Neat!  What I am hoping to eventually do is the same thing I am doing on
my Red Hat KVM guests with my  Solaris 10 ZFS KVM guests. Mount it via
libguestfs and set up the interfaces, DNS and host name so it will boot
up and be usable from a virt-clone of a template.

Looks like it will be possible. Just need to mount the ZFS root
filesystem. I am working on compiling libguestfs but I'm stuck at the
moment with febootstrap giving checksum errors on all the Fedora
mirrors. probably something minor...I hope :P

Thanks so much for helping out. This is really cool stuff.
