I deployed deployed Xen 4.10 PVHv2 (from Xen 4.7/4.9 PV) to a good 
number of hosts, VMs.  Not seeing anything too alarming as yet.
Some issues per email thread 'DomU not starting under pvhv2' where some 
CPUs don't appear to work for me.  Seems like these older CPUs are 
giving us problems:  cat /proc/cpuinfo | egrep -qai ' E4600 | E3110 | 
E5310 | E5320 | E5410 | E5420 | X3220 |Processor 4284|Processor 2212$| 
Q6600 | E4500 ' &&   echo "CPU not supporting PVHv2"
Still needing/wanting a solution for VMs currently running pv-grub or PV 
DomUs stuck on old distros that fail with pvh compatible kernels 
(4.??+).
