Thanks. Sadly these logs weren't as informative a I had hoped they would
be :-/ (In case it's not clear: this is not your fault)

This basically says "it failed", which isn't terribly helpful!

I think it is complaining because it couldn't mount xenfs, but it
doesn't say why.

If you run "/etc/init.d/xen start" from the root command line does it
say something more informative/useful?

Could you also try running /usr/lib/xen-common/bin/xen-dir
and /usr/lib/xen-common/bin/xen-toolstack by hand (also as root).

This made me wonder -- are you doing/installing this in a Xen guest
(domU)? From other evidence I don't think you are but I should check.

Assuming you are running this on the dom0/host, have you booted into the
hypervisor at this point or are you running bare-metal/native? (I
suspect the latter).

Thanks,
Ian.
