Opensuse 12.2 and VM xen hypervisor

English Virtualization
#1

**Summary
Opensuse 12.2 and VM xen hypervisor
On default installation, had issues with

  • Grub 2 (not showing any additional “sections”)
  • Yast - Virtualization menu missing
  • xen.gz missing…**

Details
12.2 Yast does not include a “Virtualization” menu by default.
Attempted to add it (yast-vm).
New menu appeared but, launching “Virtual Machine Manager” resulted in an error.

Error talking to PackageKit: org.freedesktop.DBus.Error.UnknownMethod: No such method ‘InstallPackageNames’ in interface ‘org.freedesktop.PackageKit.Modify’ at object path ‘/org/freedesktop/PackageKit’ (signature ‘iass’)

Re-installed everything, using Grub (versus Grub 2).
Now xen appears on the menu, but received file not found error 15 (/boot/xen.gz missing)

Tried to install xen from Build Service - Package Search - 1-Click Install
It “failed” without providing any clue as to what happened.

Installing xen hypervisor from sources now…

#2

Installed xen-4.3.1, rebooted (using Grub versus Grub2) successfully into xen kernel.

#3

Do the additional sections appear with grub2 under the advanced boot options ?

#4

Run this after you install xen and the entry will appear in you grub2

sudo /usr/sbin/grub2-mkconfig --output=/boot/grub2/grub.cfg
#5

Did that and received:

linux-7pgn:~ # /usr/sbin/grub2-mkconfig --output=/boot/grub2/grub.cfg

The Xen Hypervisor does show on the boot menu now.

However, when attempting to boot that option, I received:
(from my memory)

init ramdisk
error you need to load the kernel first

Before the reboot, I had installed xen-kernel

had to boot the desktop kernel

Of course when trying to run Yast-Virtualization-Create Virtual Machines, received:

**Error: A hypervisor is not running. For kvm, load the kvm kernel modules. If you want to run xen, reboot and load the xen kernel
**

This was all *too *easy in opensusse 11.4…

Appears to be the grub2 menu issue as noted above.

Is Virtualizion (XEN) working for anyone in 12.2?

#6

I did what tom mentioned and now see the option to boot XEN, but it still is not working.

#7

I ran in the same problem, I first thought that is was linked to the AMD 6234 because I have installed a few weeks before a 12.2 with xen without big problems on a xeon 3440 (except the grub2 which is a pain) this one works on a vmlinuz-3.4.6-2.10-xen with xen 4.1.

Now, even if I just upgrade xen it does not work, I tried with grub and grub2. For my understanding it’s linked to vmlinux-3.4.11-2.16-xen but I’m not able to determine what to do to make it work.

#8

Sorry not linked to grub, I opened an other thread
