Re: [Xen-users] Re: How to upgrade to Xen 4.0.1 on Centos 5.5 ?
I would stop building on CentOS 5.5 .
Any distro like Ubuntu 10.04.1 Server , F13,F12 would work for sure.
Currently i am on top F14 ( rawhide) at Xen 4.0.1 ( .21 Michael Young kernel)

make xen
make tools
make stubdom
make install-xen
make install-tools
make install-stubdom
make world => to compile the new kernel
What do I do after this ? Excuse me
for my stupid question but it''s the first time I compile a kernel.
I tried :
make install
mkinitrd -f /boot/initrd.img-2.6.32 2.6.32
But I have some errors about "No module xxx found for kernel
2.6.32.21, aborting."
I spent this step with : --builtin="ehci-hcd"
--builtin="ohci-hcd"
--builtin="uhci-hcd" --builtin="sata_nv"
--builtin="usb-storage"
After I modified my grub.con but my server doesn''t boot...
Thanks a lot for your help !

One thing that I can think of right away is CONFIG_SYSFS_DEPRECATED. You can try to rebuild my kernel SRPM (xenified kernel, not pv_ops) on an x86_64 box. It was tested for Xen 4.0, but might work on Xen 4.0.1 as well. See http://lists.xensource.com/archives/html/xen-users/2010-07/msg00452.html for details, and possibly http://wiki.centos.org/HowTos/RebuildSRPM on how to rebuild SRPM (if you don''t know how). Or you could try customizing the config your downloaded pv_ops kernel (not so easy for first-time users). Or you can simply use latest xen 3.4.x RPM from Gitco ( http://www.gitco.de/repo/), which works well with Centos'' kernel-xen. It does not have the latest features (like blktap2), but should be good enough for normal uses. Or, as Boris suggested, use a different Linux distro as dom0. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

So the combination works now? Good to know. Previously
RHEL/Centos

The biggest difference that I can think of moving from
the stock
Centos Xen to Xen 4.0.x is that it''ll be possible (or
at least easier)
to work with some types of PV domUs (like Ubuntu and
Opensolaris).
However you''d need a new dom0 kernel if you also want
to try out newer
features like blktap2.
For common purposes though, I highly recommend to just
stick with your
current setup, using stock Centos kernel-xen.

It''s not there. The networking setup changed so the
bridge is called eth0 now.

Just change all reference of "xenbr0" to
"eth0" on
domU''s config file
(or don''t specify a bridge name), and you should be
fine.

In meantime i can load Dom0 with 2.6.18-194.11.3.el5, but xend fails to start,
2.6.18-194.11.4.el5 gets installed by default via gitco, but Dom0 loading
hangs ( looks like AHCI problem)
