Sorry for the long delay, just come back from vacation...
Change from v8:
1. Update struct kvm_run to contain MSI-X routing update exit specific
information.
2. Fix a mmio_nr counting bug.
Notice this patchset still based on 2.6.37 due to a block bug on assigned
device in the upstream now.
Then it can be used by other struct in kvm_host.h

The old MSI-X enabling method assume the entries are written before MSI-X
enabled, but some OS didn't obey this, e.g. FreeBSD. This patch would fix
this.
Also, according to the PCI spec, mask bit of MSI-X table should be set
after reset.

This is required to support keeping VCPU states across a system reset.
If we do not read the current state before the reset,

The current way of injecting MCE events without updating of and

As a first step towards a fix, enhance the state writeback code with

Round 2 of this part, primarily addressing review comments:
- Reworked CPU_INTERRUPT_MCE - exection translation
(now done in kvm_arch_process_async_events, indeed much cleaner)
- Add missing cpu_synchronize_state on pending MCE events for
!kvm_irqchip_in_kernel
- Split up KVM MCE code

This switches KVM's MCE injection path to cpu_x86_inject_mce, both for
SIGBUS and monitor initiated events. This means we prepare the MCA MSRs
in the VCPUState also for KVM.
We have to drop the MSRs writeback restrictions for this purpose which
is now safe as every uncoordinated MSR injection is

If VM params define a new NIC that didn't previously exist, then when
make_qemu_command() is called in order to see if the VM should be restarted,
it attempts to get the MAC address of the new (nonexistent) NIC, and an
exception is raised. This exception is expected and should be caught.
get_mac_address() should first check if 'nic_mac' is defined and then check
the address pool. This way, if 'nic_mac' is changed between tests,
make_qemu_command(), which calls get_mac_address(), will reveal the change and
trigger a VM restart.
