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.

Why thank you for the quick reply :)

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
2.6.32.26-174.xendom0.fc12.x86_64

grub.conf part

title Fedora (2.6.32.26-174.xendom0.fc12.x86_64)
root (hd0,0)

initrd /initramfs-2.6.32.26-174.xendom0.fc12.x86_64.img

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
ERROR Internal error: Could not obtain handle on privileged command
interface (2 = No such file or directory)

    xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on

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.

 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.

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

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

Why thank you for the quick reply :)
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 -r2.6.32.26-174.xendom0.fc12.x86_64

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 4.0.1pv_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.

I think you need to enable CONFIG_XEN_COMPAT_XENFS to get the mount
point. Quoting that option's help text:
         The old xenstore userspace tools expect to find "xenbus"
         under /proc/xen, but "xenbus" is now found at the root of the
         xenfs filesystem.  Selecting this causes the kernel to create
         the compatibility mount point /proc/xen if it is running on
         a xen platform.
         If in doubt, say yes.

If that doesn't help then please post a complete boot log and
your .config.

Also, please avoid cross-posting to both xen-users and xen-devel in the
future.

Ian.

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

[Keir Fraser]

You may need a line like this in /etc/fstab:
none /proc/xen xenfs defaults 0 0

You don't need it. That was for when systemd was the default init in the 
Fedora 14 alphas and betas but they decided it wasn't ready yet and pushed 
it back to Fedora 15. You would still need it if you were testing that 
kernel with rawhide but hopefully there will be better kernel options by 
the time Fedora 15 is released.
