I have a 32bit(PAE) CentOS5 machine running (stock CentOS) Xen. I've been using the kernel dummy ethernet driver to create interfaces on the host machine so that I can create internal networks for the guests and host to communicate with each other. The only issue I have with this is that the interface is not >=100MB, but is 10MB.
Is there a way I can increase the speed of these interfaces (I've tried looking at the kernel docs and google'ing) or another dummy style interface driver I can use to create these?
Thanks!

Caitlyn, Are you sure you're only getting 100Mb or is it identifying itself as 100Mb? Actual speed and info it's applied to itself may be different.

Some people, when confronted with a problem, think "I know, I'll use Windows." Now they have two problems.

I just tested my dummy0 network connection and I can scp at 40MB/sec which definitely puts it above the 100Mb/sec limit. Where does it identify itself as being 100Mbit?

Actually, I don't know how to tell it its speed, or for that matter I seem to not be able to find out what it thinks its speed is. And, of course when I try doing an scp, it xfer'd a 100MB file at ~16.7MB/s, so this may have just been an issue in the past and has magically changed speeds (I hate random magic...). I do remember doing an scp and seeing only ~1MB/s speeds.
For completeness, and I'd also like to bump it up to 1000Mb/s or higher if I can, how would I go about finding out it's speed and changing it? ethtool says 'No data available' and mii-tool says "SIOCGMIIPHY on 'pdummy0' failed: Operation not supported".
Thanks for any help :)
