I've even seen them on some reasonable desktop motherboards. Some enabling features that are turned off by default.īy the way, in answering 'How common are intel igb NIC vs e1000 etc? Very common. Reading through some of the release notes of the igb driver and there were numberous bug fixes. Perhaps the update provided by VMWare may not be available in the normal update channel because it's not been thoroughly tested? After all, what they are providing is a backport of the driver to the specific kernel they are running with ESXi. Do VMWare provide the same sort of facility? XenServer provide a DDK to allow you to insert other kernel drivers. Even the latest version of XenServer is using a 2.6 series and a distro based on Centos 5.6. It would be a similar story to XenServer. I suspect he reason the driver is so terribly old is that it's tied to an the kernel version that ESXi is based on. Especially if you don't see issues with these cards/nic chipsets under windows. I think the problem is likely the igb driver. The I/O overhead on a virtualized platform.
