RE: [Xen-users] howto build xen from source with existing config?

["Philippe Trolliet" <p.trolliet@xxxxxxxxxxxxxxx>]

hi,

i updated my FC6 and it uses the 2.6.20-xen kernel. so i want to use this version.

it should be possible to use this kernel and its config in xen 3.1 compile process. i mean, how are the people of redhat doing that?

they released a newer xen-kernel.

i´ll just try it like the way you described but with the 2.6.20 config.

 

regards

philippe

Hey,

 

dont know if this is any use to you but i found that booting in xen mode and running

 

make oldconfig

 

in the linux-2.6.18-xen directory

 

seems to import the exiting XEN config into the new one.  Just hold down enter when it prompts for different elements :)

 

thanks

You should be able to use the config for another kernel, as long as the config is for the same base-level kernel (e.g. it may not work to use a 2.6.18 config to build a 2.6.20 kernel, and probably even worse the other way around).

As stated in a post yesterday, the best way to achieve this is to wait for one of the distributors to do the hard work of figuring out how to adopt the kernel patches from Xen into the next version of the kernel - because that's what you'll have to do.

However, if you want to go with the current FC6 Dom0 kernel, and use the new 3.1 tools and Xen Hypervisor, that should work ok.
