RHEL6.4 guest alwasy crashes and reboots. 32bit RHEL6.4 and 64bit RHEL6.3
guest can work fine.
kvm next + qemu-kvm uq/master = result

Initialize IA32_FEATURE_CONTROL MSR in reset and migration
The recent KVM patch adds IA32_FEATURE_CONTROL support. QEMU needs
to clear this MSR when reset vCPU and keep the value of it when
migration. This patch add this feature.
Reproduce steps:
----------------
1. qemu-system-x86_64 -enable-kvm -m 1024 -smp 2 -net none /root/rhel6u4.qcow
Current result:
----------------
guest reboot continuously
Expected result:
----------------
guest boot up fine
Basic root-causing log:
----------------------
(guest serial port log is attached.)
