Re: [libvirt] [Qemu-devel] [QEMU PATCH] target-i386: Disable rdtscp on Opteron_G* CPU models

KVM can't virtualize rdtscp on AMD CPUs yet, so there's no point in enabling it by default on AMD CPU models, as all we are getting are confused users because of the "host doesn't support requested feature" warnings. Disable rdtscp on Opteron_G* models, but keep compatibility on pc-*-2.4 and older (just in case there are people are doing funny stuff using AMD CPU models on Intel hosts).
