Alexandre Derumier 0dc48c3d5b cpuflags : remove -rdtscp for Opteron cpu models
rdtscp is not supported by qemu and with enforce it's not starting
warning: host doesn't support requested feature: CPUID.80000001H:EDX.rdtscp [bit 27]

from to qemu wiki
http://wiki.qemu.org/Features/CPUModels#Disabling_features_that_were_always_disabled_on_KVM
"Fact: currently libvirt runs CPU models having rdtscp without the "enforce" flag, and rdtscp is silently disabled
Consequence: libvirt SHOULD use something like "-cpu Opteron_G5,-rdtscp",
especially when it starts using (or emulating) enforce mode
This will require a solution on libvirt side. QEMU will just provide the mechanisms to report CPU model information
and check what the host and QEMU supports, but the decision to disable rdtscp to be able
to run Opteron_G[2345] needs to be taken by libvirt."
