View Full Version : Xen Kernel in Fedora Core 6

Hi,

I had a couple of questions about the Xen Kernel in Fedora Core 6.

1) I understood Xen as being a virtualization environment, so how can the kernel be referred to as a Xen kernel?

2) Is the virtualization now inherent to the kernel? I also noticed that this is the default for the installation of Fedora Core 6.

3) Are there any drawbacks to using this Xen kernel?

4) Does this kernel support smp? I noticed that a uname -nr shows i686. If not, then which one does?

Thanks so much!

Cheers,
Saki

Xen requires kernel modifications for their paravirtualized approach. Fedora ships kernels with and without these modifications.

Xen is not installed by default.

Xen causes some complications and weirdness that I can't quite explain, especially when working with proprietary modules and junk not built for it.

All kernels are SMP enabled now. You can see the config option with
grep CONFIG_SMP /boot/config-`uname -r`
