Perry asked me to point this out on the list, since I was doing some testing today. Currently, if you run a RHEL-3, RHEL-4, or RHEL-5 x86_64 guest on an F-9 based oVirt node on AMD hardware, they will very likely fail to boot with a panic in setup_k7_watchdog (or thereabouts). This arises because of a bug in kvm in 2.6.26, which is the current version of the kernel in F-9. The good news is that the patch I submitted to fix this is already in 2.6.27 (and hence rawhide), and this issue only affects AMD hardware at present. Once F-9 rebases to 2.6.27, we'll also automatically pick up the fix, but until then, just be aware that this issue could affect you. -- Chris Lalancette
