Add suport for invariant TSC flag (CPUID 0x80000007, bit 8 of EDX). If this flag is enabled, the TSC ticks at a constant rate across all ACPI P-, C- and T-states.
This can be enabled by adding: <feature name='invtsc'/> to the <cpu> element.
Migration and saving the domain does not work with this flag.
QEMU support for this is not merged yet: https://lists.gnu.org/archive/html/qemu-devel/2014-04/msg05024.html
In spite of Dan's ack, let's wait until it actually lands in qemu.git before you push this. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
