[opensuse-virtual] [Fwd: virtualisation: xen vs kvm]
As Per suggested, i'll try on this list as it is more on-topic. I grew up with XEN, so i rather stick with it (inertia ;-) but if it isn't maintained anymore, i'll ditch xen and start looking at LXC (for linux) and KVM (for non-linux).

hi all,
afaicr there are several ways om virtualisation techniques available under suse. What is currently advised for doing an virtual suse machine on hardware running 12.2? XEN or KVM?
Reason for asking is that it seems that xen-through yast doesn't work anymore. I booted up the xen-kernel and tried to create a machine through yast2-module. -kept paravirtualized -defined mem 1024 def./2048 max. -iso-image, 10GB disk -paravirt network adapter (fixed mac), on a proper working br0.
after pressing OK, it just yields: "unable to connect to libvirt with URI (none)" and "No kernel was found. the installation may have failed."
tried: - 64-bit in stead of 32-bit iso-image - plain 10GB file instead of logical volume - full instead of para
The log in /var/log/xen/domain-builder-ng.log only says that loader-probe fails because the kernel isn't a bzImage.
Up till 11.4 i used to create xen-image on the fly this way. Any suggestions?
Hans

Why are you using 4.2.0? The Xen shipped in 12.2 is 4.1.3, and works just fine. I even have esoteric features like VGA passthrough working. If you are having trouble with stock 12.2 plus updates, you can file a bug report. As for maintenance, Xen is very well maintained on openSUSE. I have many production openSUSE Xen machines and when I file bug reports, issues are usually solved pretty quickly. -- James Oakley jfunk@funktronics.ca -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org

At a meeting, i was informed that LXC from the addon repo was significantly improved. I'm removing the addon, and will try XEN again. will report back on it. hans -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org

As said, i would report back. It seems i met another pygrub-"issue", If you start with the yast2 module, remove the default disk and 1) add a bootable cdrom and _next_ 2) add you boot/root disk, you get a problem where the system starts to install but fails after the initial reboot. However if you swap them, eg: 1) _first_ add the disk that will hold /boot, 2) _next_ add the iso image all works fine... Seems it was known on the xen-users-list....

Probably because you're making the CDROM the first entry, which is the one Xen will boot from. For installation, just specify the actual disks in this section. You can specify the CDROM, or even better, an installation URL, in the installation settings section later. -- James Oakley jfunk@funktronics.ca -- To unsubscribe, e-mail: opensuse-virtual+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-virtual+owner@opensuse.org
