Currently, RHEL-4.7 and RHEL-5.3(preview) KVM guests will crash on bootup
on Intel machines running F-9 kernels. This is because of a bug in the way that
KVM emulates performance counter MSRs. This was fixed upstream by this commit:
However, it fell into a strange window and missed both 2.6.25 and 2.6.26, but is
now in 2.6.27 (which means F-10 will be just fine). In the interest of helping
out the Fedora users (especially for Bugzilla bug 462177 and duplicates), I
backported this very simple patch to the current head of F-9 CVS (188.8.131.52).
The patch is attached. If there are no objections, can someone please commit this?
