Not quite. Bromiums solutions make use of VT-x/VT-d/EPT. This is pure para-virtualised approach. Atleast from what I can see, it's possible it uses VT-x/VT-d/EP

Not quite. Bromiums solutions make use of VT-x/VT-d/EPT. This is pure para-virtualised approach. Atleast from what I can see, it's possible it uses VT-x/VT-d/EPT to implement the process isolation - just somewhat unlikely given how it's presented.
