Re: [Xen-users] Xen 3.1 SEGV when running old binaries in FC1

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

Hi Nick,

FC1 did have some crazy stuff going on (e.g. a 2.4 kernel with NPTL), so I 
guess it's possible HVM mode isn't handling that right for some reason.

Is the Xen version the only thing you've changed between the two installs?  If 
so I guess it could be a regression that'll need bugfixing.

Cheers,
Mark
