Just for the mail archives -- I have installed vanilla 6.4-RELEASE
(amd64) as HVM ("Fully virtualized" in SuSE-speak) guest under OpenSuse
11.0 x86_64/Xen 3.2.1. I have not done much beyond building world with
both UP and SMP kernels. I have seen some 'calcru: negative runtime ...'
and 'calcru: runtime went backwards ...', but otherwise no ill effects
Machine is Dell OptiFlex 740 with Athlon 64 X2 4200+.
