context switch between HVM and idle domain
...d a HVM on xen which os is linux(debian), and pinned it to a
particular core. When try to send ipi to this core from xen, I find
the ipi receiver is idle domain whose domian id is 7FFFU. Then I want
to get the real domain pinned to that core. Because I use AMD CPU, I
have a test to get domain id in svm_ctxt_switch_to function. The
result was not like my expection. I even not get any hvm context
switch when all guest domains were ready. What happened when idle
domain switchs to hvm domain? Is there other method to achieve my
goal?

[PATCH] svm: support VMCB cleanbits
Hi,
Attached patch implements the VMCB cleanbits SVM feature.
Upcoming AMD CPUs introduce them and they are basically hints
for the CPU which vmcb values can be re-used from the previous
VMRUN instruction.
Each bit represents a certain set of fields in the VMCB.
Setting a bit tells the cpu it can re-use the cached value
from the previous VMRUN.
Clearing a bit tells the cpu to reload the values
