Hi,

I'm just thinking about the pros and cons of VT-d. On one side, it does improve performance of guest domain to provide more direct access to HW by walking around hypervisor; while on the other side, it also reduce the abstraction layer of hypervisor which could make the live migration more difficult.

Could someone here give me a best balanced point when considering vt-d for Xen guest domains?

Thanks,

Liang
