RE: [Xen-users] 82574L PCI Express NIC in Xen

[Jeff Sturm <jeff.sturm@xxxxxxxxxx>]

Intel is usually a safe bet for networking, and the e1000/e1000e drivers
are ubiquitous.  We run CentOS and I've never had to go looking for a
network driver for my distribution.

Are you looking for that exact chipset for a reason, or do you just need
a PCI-Express GigE card?  The chipsets undergo frequent revisions, and
newer models may be improved compared to what you used prior.

You can get these on Amazon.com too, if you like.  Here's an example:
