I build 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
