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 _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
