xen 3.4.1 + myoung x86_64 kernel

[Mark Schloesser]

Hi,

I was just trying to get this combination setup up and running. I am on
Fedora 11 and mostly followed Boris Derzhavets' blog to get it done.

Sadly the box complains that it can not connect to the hypervisor when
starting libvirtd and also xend startup fails.

libvirtd screen message:
ERROR Internal error: Could not obtain handle on privileged command
interface (13 = Permission denied)
FATAL: Failed to open connection to hypervisor: Permission denied

In the kernel log I saw this:
======================================================
[ INFO: SOFTIRQ-safe -> SOFTIRQ-unsafe lock order detected ]
2.6.31-0.1.2.60.rc7.git4.xendom0.fc12.x86_64 #1
------------------------------------------------------

See dmesg at http://p.carnivore.it/MrGxdQ for more info.

Thanks for any hints or clarification!

Cheers,
Mark

Did you build and and start services as root ?
After xen-3.1.4-3.src.rpm "rpmbuild"  followed by install of  generated packages run:-
 
# chkconfig xend on
 
# service xend start
Same commands for xenstored,xenconsoled,xendomains

Configure Libvirt Preview Repo and run :-
# yum install libvirt libvirt-python python-virtinst virt-manager virt-viewer

# chkconfig libvirtd on

# service libvirtd start

Next :-
# rpm -qa|grep xen
# rpm -qa|grep virt

Make sure right packages installed on F11

Boris.

Thanks Boris, I finally have xen running!

I started over with a fresh F11 install and used JF git kernel with
xen-3.1.4-3.src.rpm. The system starts up just fine with or without xen
enabled on this 2.6.31-rc6 kernel.

The GDM/Xorg does not work though. I have an nvidia NVS290 in this
machine and the nouveau driver complained about not being able to load
the kernel module - directly followed by a backtrace dump in the Xorg
log. I then disabled the nouveau driver trying to get it done with vesa
driver - seemed to give no errors but ended up in the same kind of
backtrace.

on vesa:

Backtrace:
0: /usr/bin/Xorg(xorg_backtrace+0x26) [0x4e89b6]
1: /usr/bin/Xorg(xf86SigHandler+0x6f) [0x47d63f]

12: /usr/bin/Xorg [0x42c559]

any hints on how to get X back up again?

Thanks,
Mark

I somehow did not search deeply enough - there was a related discussion
on xen-devel mailing list. It is a little hidden in the "Vt-d not
working with 3.4.1" thread. There does not seem to be a final "i got it"
post though - I'll try some different solutions proposed there.

I believe, you have to enable Xen Privileged Domain Support in JF kernel
to load it under Xen 3.4.X Hypervisor.
Otherwise, Dom0 won't be loaded.

Thanks Boris, I finally have xen running!

I started over with a fresh F11 install and used JF git kernel with
xen-3.1.4-3.src.rpm. The system starts up just fine with or without xen
enabled on this 2.6.31-rc6 kernel.

The GDM/Xorg does not work though. I have an nvidia NVS290 in this
machine and the nouveau driver complained about not being able to load
the kernel module - directly followed by a backtrace dump in the Xorg
log. I then disabled the nouveau driver trying to get it done with vesa
driver - seemed to give no errors but ended up in the same kind of
backtrace.

on vesa:

Backtrace:
0: /usr/bin/Xorg(xorg_backtrace+0x26) [0x4e89b6]
1: /usr/bin/Xorg(xf86SigHandler+0x6f) [0x47d63f]

any hints on how to get X back up again?
