Subject: [PATCH] qemu_process: Prefer generic qemuMonitorGetGuestCPU
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
When updating guest CPU definition according to the vCPU actually
created by QEMU, we want to use the generic qemuMonitorGetGuestCPU to
get both CPUID and MSR features.
