Public bug reported:
When using libvirt to give a domain 2 CPUs (2), the Windows XP kvm process will use
200% CPU when Windows is idle. Switching the number of CPUs back to 1,
the kvm process gives normal idle percentages.
Using libvirt 0.8.3-1ubuntu9, tried with the following qemu-kvm
packages:
pcibus_dev_print() was erroneously retrieving the device bus
number from the secondary bus number offset of the device
instead of the bridge above the device. This ends of landing
in the 2nd byte of the 3rd BAR for devices, which thankfully
is usually zero. pcibus_get_dev_path() copied this code,

This fixes an observed failure to detect madvise() on Linux.
To avoid similar issues, all other tests that use NULL but don't already
have stddef.h are also fixed.

This will deadlock when the I/O thread is used, since the
CPU thread is blocked waiting for qemu_system_ready.
The synchronization is unnecessary since this is before
cpu_synchronize_all_post_init().

From: Huang Ying
In QEMU-KVM, physical address != RAM address. While MCE simulation
needs physical address instead of RAM address. So
kvm_physical_memory_addr_from_ram() is implemented to do the
conversion, and it is invoked before being filled in the IA32_MCi_ADDR
MSR.

ATA does not only have the WCACHE enabled bit in identify word 85, but also
