To run Windows hardware-assisted virtual machine (HVM) domains, an HVM-capable machine that is running a Solaris xVM dom0 is required. A machine is HVM-capable if it is has either an AMD Opteron Revision F or later, or an Intel CPU with VT extensions.
To determine whether a machine is HVM-capable, run the virt-install program with the -v option.
If HVM is not supported, an error message displays:
# virt-install -v ERROR Host does not support virtualization type 'hvm'
