[Xen-users] kernel-3.0-0 dom0, python2.7, and xen 4.0.x on ubuntu 11.10
list,
Ubuntu 11.10 has kernel-3.0-0 (since about a week) and its ready for dom0. The
important dom0 modules needed for domU are built `=m` and they must be loaded at
startup for xen to work and create domU.
11.10 is changing quickly and I have no development packages installed yet.
It seemed frugal to try some 4.0.x builds that succeeded on 11.04 where
python2.7 is stock - same with 11.10.
This required using xen-4.0.x/install.sh while in 11.04 with 11.10 fs mounted
and running the install script.
I tried first with xen-4.0.2, but failed after trying for 2 hours to get it
working.
4.0.1 worked after a few easy mods.
There is a problem with /dist/install as applies to Ubuntu, where we have
`ls /usr` ->
bin games include lib lib64 local sbin share src
the directory list is flat. lib64 is also a dir, not a symlink to lib.
to fix it.
--------
cd ./dist/install/usr
cp -a ./lib64/* ./lib
rm -rf ./lib64
then `sh ./install.sh /mnt` does the right thing, where /mnt is the destination
fs.
Patch set for 11.04
-------------
to build xen-4.0.1 on 11.04 requited this patch set:
http://paste.ubuntu.com/544701/
although xend starts in 11.10, there is an xmlrpc bug fixed via this
