I was reading an article about Windows PE 2.0 in virtual environments, and apparently Windows PE 2.0 is based on Vista, which doesn''t have a driver for the default NIC used by VMWare. The suggested solution is to use a different virtual NIC (a gigabit one). Obviously Xen isn''t VMWare, and on top of that, I am not trying to run Windows PE 2.0, or even Vista. However, I had long wondered but never asked this question: Does Xen have any virtual NICs other than the two mentioned in the hvm example files in /etc/xen? More importantly, does it matter, for instance, will Xen or Windows limit the response time or throughput to 100MB/s levels in an hvm environment if a 100MB/s virtual NIC is used? I don''t see why it would, but then again, I don''t see why SATAII hard drives running on controllers in IDE mode are slowed to IDE speeds, so I wouldn''t be surprised if it did, and I am hoping someone can tell me.
