[Xen-users] pv guest fails to start after 4.2 upgrade

[Travis Osterman <tosterman@xxxxxxxxx>]

I'm running xen on gentoo (3.7.0 hardened) and upgraded from 4.1 to
4.2 yesterday as 4.2 is marked as stable in the portage tree.
Afterwards, I cannot start my guests and get the following error
(currently running 4.2.1).  Any help in troubleshooting would be
greatly appreciated.  Thanks in advance.
