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

[David Gonzalez Herrera <dgonzalezh@xxxxxxxxx>]

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)

kernel /xen.gz loglvl=all guest_loglvl=all noreboot lapic=debug iommu=off

kernel /vmlinuz-2.6.32.26-174.xendom0.fc12.x86_64 ro root=/dev/mapper/gw-root init=/sbin/upstart nomodeset selinux=0 rd_LVM_LV=gw/root rd_LVM_LV=gw/swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=es rhgb

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)

xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle on privileged command interface (2 = No such file or directory)')

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 (http://www.xen.org/download/roadmap.html)
