HVM guests and pvlocks not working as expected
...g set up correctly (which Stefano has posted
patches) and even with those 3.0 guests seem to hang for me while 2.6.38 or
older kernels were ok.
After digging deeply into this, I think I found the issue. However, if that is
true, it seems rather lucky if pv spinlocks in HVM worked for anybody.
The xen_hvm_smp_init() call will change the smp_ops hooks. One of which is
smp_prepare_cpus. This is done in start_kernel and at this point in time, there
is no change to the pv_lock_ops and they point to the ticket versions.
Later in start_kernel, check_bugs is called and part of that takes the
pv_lock_ops and patches...

[PATCH 0/4] Add posted interrupt supporting
From: Yang Zhang <yang.z.zhang@Intel.com>
The follwoing patches are adding the Posted Interrupt supporting to Xen:
Posted Interrupt allows vAPIC interrupts to inject into guest directly
without any vmexit.
- When delivering a interrupt to guest, if target vcpu is running,
update Posted-interrupt requests bitmap and send a notification event
to the vcpu. Then the vcpu will handle this
