I'm not sure how much of the issue is gentoo 2.6 kernel specific vs generic 2.6. At the very least, I know that 2.6 has HZ set to 1000 by default which isn't very scaleable. Also, some vmware kernel modules, especially for ESX, will not compile under 2.6.x (unless someone has patches I haven't found). > > - GSX and ESX support a greater range of hardware drivers, in particular, > > the vmxnet nic driver which isn't detected in 2004.3. > > Show me where I can get it, and I'll include it. > It's part of vmware tools.

We can always force users to manually put the tar ball in distfiles, like I believe we do with the vmware workstation downloads. Most of my ESX/GSX installs share a nfs mounted distfiles so that would work fine for me too. I do see some issues with various versions of vmware requiring different releases of vmware-tools. ESX 2.1 might require different from GSX which might require different from workstation 5 beta? Regards, Matt
