[Xen-users] Fedora Core 4 Questions and Building a 2.4 domU kernel

Hi Everyone,

I''ve been using and testing Xen for use in the QA Lab that I manage.  
I
have FC4 setup and a few FC4 domU''s running without a hitch using the
xen rpm''s that come with FC4.  This morning, after a few days of
banging
my head on a very hard object, I finally got a RHEL3 (Update 4) domU
working, but using the 2.6 domU kernel that FC4 provides.  (I can post
instructions if anyone would like them).  I would like to compile a 2.4
domU for my RHEL3 domU, but have been unable to do so.   My questions
are as follows.

1)  Does FC4 provide tools to build new dom0/U kernels using the
20050522 snapshot?  I have been unable to find any.

2)  I have downloaded the lasted Xen-unstable snapshot using the
mercurial tools, and have been attempting to compile a 2.4 domU, but I
keep getting mkbuildtree errors.  (hg pull/hg update)

make[2]: Entering directory `/root/xen-unstable.hg''
rm -rf linux-2.4.30-xenU
cp -al ref-linux-2.4.30 linux-2.4.30-xenU
# Apply arch-xen patches

          ./mkbuildtree ../linux-2.4.30-xenU )

make[1]: *** [linux-2.4-xenU-build] Error 2
make[1]: Leaving directory `/root/xen-unstable.hg''
make: *** [kernels] Error 1

After browsing this mailing list, there appear to be a few people that
have been trying to update the 2.4 patch tree, but have not actually
tested it to see if it builds, I have been following Shahzad Chohan''s
posts/requests for help with interest as it seems that we are in a
similar situation.

I built a 2.4 domU kernel using Xen 2.07, but it fails to boot giving a
Xen version mismatch error:

ERROR: Error constructing guest OS

I guess you could install the source RPMs, tweak the config however you want 
and then build new binary RPMs out of them?

Yeah, 2.4 is broken in unstable at the moment - action is being taken to 
correct this.
> Xen version mismatch error:
Binary interfaces are only stable during a release series of Xen: 2.0.y 
kernels work on 2.0.x Xen.  You can''t run 2-series kernels on unstable
(or
vice versa).  With unstable you need to run kernels *from the same snapshot* 
as Xen itself if you want  to guarantee compatibility.

The 3.0 series will again have a stable interface (which should be supported 
for a long time).

Cheers,
Mark
