Hi,

I played a little bit with the xenoprof interfaces on a PV domU and things 
work fine. But on a simple HVM domU these hypercalls failed with
"hvm.c:515:d1 HVM vcpu 1:0 did a bad hypercall 31."
I found that Xenoprof hypercallse are not supported in hvm_hypercall64_table.
Is there really a problem as it seems to me that the xenoprof stuff shouldn't 
be that different on PV and HVM?
Many thanks.
Dietmar.
