Re: Using the -xen kernel rather than -xen0/U was [Xen-users] Poor hard
I used the xen 3.0 rpm's from xensource on centos 4.1, and was kind of surprised to see a single kernel. Now seeing these posts explains it.
Thanks guys for such a nice job :)
Would love to see more detailed explanation for building the kernel.
Would you advise to keep using the rpm or compile the kernel for production use ?

This is very good advice, and easy to follow. If you are building Xen
for testing or production use the "xen" kenel. It is much more like
the kenel in most distributions, everything compiled as a module.
Just edit the top level Makefile so that this line:
KERNELS ?= linux-2.6-xen0 linux-2.6-xenU
looks like this
KERNELS ?= linux-2.6-xen
You will get a single kernel and modules which can be used for both
Domain0 and all DomainUs.
Copy the modules directory /lib/modules/2.6.whatever-xen to the
/lib/modules directory of your VM and make an initrd with mkinitrd.
You will need to add the initrd to your grub config.
Takes a little longer to build the kernel this way, but for most
people it is much easier to deal with.
If this is not documented it should be. I will take a look at the
wiki over the weekend and add something if it is not already there.
