RE: [Xen-users] Re: Custom DomU kernel
|
Hi,
Thanks for the quick reply - what would a lot of hard work
imply? Having this configuration and the RHAS image running was quite a
lot of hard work as well, so I'm not scared :)
Figuring out how to apply
the patches developed by Xen for 2.6 onto a 2.4 kernel, and fix any problems
that arise from the fact that the 2.4 kernel is different from 2.6, so you
may need patches in different places than they are for 2.6. The xen 2.0
hypervisor has patches for Linux 2.4 kernels, so you may be able to get an
idea of how it works from that - but the Xen 2.0 hypervisor is different
from 3.0 in several aspects, which would mean that the patches need to be
different - so if you compare the 3.0 patches for 2.6 and 2.0 patches for
2.6, you'd see how different (and I haven't done this) the patches are for
the different Xen versions. Based on that, you should be able to determine
what the work needed for 2.4 is... But since there hasn't been any
announcement of such a patch being available, I suspect it's not
trivial...

Right - sounds like fun. What if I use Xen 2 on my 2.6 kernel in
place of Xen 3? Would that even be possible?
I
guess that is a possibility - but you'll be missing some of the new features -
which of course may be less important if you don't need any of them...
:-)
Since
I work on HVM, I sort of can't choose - it's 3.0.x that works, and nothing
previously...
