Re: [Xen-users] XEN 4.0.1 + pv_ops Kernel + CentOS 5.5 x86_64, is there

Changed it, and unfortunately the error when starting xend shows up again.

Thank you for your help I got a little further ;)

I've already tried all that, however not used the init=/sbin/upstart.
It boots using the myoung pre-built RPM xend doesn't start, In fact I
wanted to paste some of the output I get

[root@vmhost ~]# uname -r

Your grub line is wrong, it should be module after the first kernel.  I'm sure that replacing the second instance of kernel with module in your grub.conf will get you a little further.
The xen build howto also stated to use the "/proc/xen" mount on
/etc/fstab, I have that but boot compains about the mountpoint not
existing.

mount: mount point /proc/xen does not exist

and finally:

[root@vmhost ~]# xend

Weird 'cause that error only showed up when you don't have a xenified
kernel loaded but my uname says the countrary, so I'm lost.

I'm compiling the kernel with the instructions/.config file found on
your link, I'll try to boot it and will tell you the outcome.

Any ideas on what to do?

Thank you people.

Hi

As you may've seen from my last posts I'm struggling to get the setup
on my subject line to work without flaws.

I've tried compiling the Kernel from Source, I've also tried Fedora
14, which has a flaky pv_ops Dom0 kernel which DOESN'T work at all,
but none of these seem to work.

I'm a mid-time XEN user, I just love it and want to stay away from KVM
 but the migration path is too rough when you want pv_ops Dom0, and
all seem to be just projects, TODOs and snapshots, nothing really
serious IMHO there's lots of misleading info and there are many gaps
on existing howtos, I've read that SuSE has back-ported some stuff
from 2.6.3.x branch into 2.6.18 but I want native and I don't want to
be toying around with Debian'ish stuff in production environments.

I'd like to keep using RH like system because of their robustness and
because I'm used to work with it as a RHCE.

Please, would you help me find a distro which would integrate

RH like 
XEN 4.0.1
pv_ops Dom0 kernel

I want to run telephony stuff on them and tho I kinda got my Openvox
A1200P card to work 50% of the times now with xen 4.0.1 it won't work
but I guess that's because I'm using Kernel 2.6.18.x with XEN 4 which
is not recommended.

Any advise will be deeply appreciated.

Thank you.

 Hi,
Has there been any development in the OVF support for Xen?
It was in the roadmap of Xen 3.4
