No.
This will not build a kernel with Xen support.
You would need to activate the proper Xen options by yourself if you compile your own kernel.
But as I said, the Xen setup will compile one for you, a 2.6.16 or 2.6.18 I believe.
Not a recent one, but a working one.

Xen needs special parameters from the kernel, so a re-compile is in order to get DomU and Dom0 support.
But with the standard Xen install, it will download a 2.6 kernel, and compile it to work with Xen.
Unless you want to use your own kernel, then you need to compile it with Xen support

Was reading: http://gids.ovh.nl/KernelInstall

Didn't see any information for EG AMD/Debian systems - just wondering if anything changes, also do I need to do the 'network reverse' thing?

I updated a kernel manually last time from http://www.kernel.org/ - does doing it using one of OVH's images make a difference/provide something better/easier?

You can install any kernel of your choice using netboot or even without it.

Following on from this 'netboot' - does Kernel remain the newest even after restart, or does it return to original installed? Why doesn't OVH simply update default kernel's rather then provide 200 (over exaggeration) different newer ones?

Is there any advantage, other then ease, to netboot?

Hi

Why do you need to change the Kernel? We offer neboot kernels if you need to change the version.

However if you want to change the kernel you will need to compile your own, this can be done and someone has created an unofficial guide, http://ovhwiki.com/index.php/Installing_your_own_kernel
