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
( cd linux-2.4-xen-sparse ; \
./mkbuildtree ../linux-2.4.30-xenU )

make[1]: *** [linux-2.4-xenU-build] Error 2

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:
