trimming the guest Linux kernel

[bfc]

Has anyone seen a writeup of Linux kernel features that would be useless if its run as a guest?

For example, the power management options of Linux.. are they of any use to a guest OS?

I'm not knowledgable enough to use common sense here, but as I try to rebuild as lean a kernel

as possible, i suspect that there are quite a few things that really aren't useful to the guest

OS. There's some idle-processor handling that I'm also suspicious of.

TIA!

I've not seen any write up.

The following options are normally useless:

\- any SCSI driver if you use virtual IDE disk

\- any networking driver which is not lance or e1000. If you use vmxnet all are useless

\- bluetooth, infrared and firewire-support

\- any dial-up support - this usually provides your host

I guess there are a lot more - especially hardware related
