Install Xen on an F18 host without LVM
by Jeroen Lankheet 23 Feb '13

23 Feb '13

Hi, I just installed a minimal F18 host on which I want to run some guest hosts. Problem is that the minimal installation of Fedora 18 left out LVM. I could create a disc image for my guest host, but I am afraid that this comes with a performance penalty. The host system is already running Xen. Can anyone advice me on whether I'm better off reinstalling with LVM or that going without LVM is Okay? Thanks, Jeroen L

Peculiar errors with libvirt/virt-manager/xen in F18
by Major Hayden 19 Feb '13

19 Feb '13

Hey there, I just installed Fedora 18 on one of my servers and installed xen, libvirt, and virt-manager. When I tried to create my first VM with virt-manager, I received some libxl errors which led me to this orange block of text: http://wiki.xen.org/wiki/Fedora_Host_Installation#Installing_the_Virt_Tools After removing libvirt-daemon-driver-libxl, I noticed that libvirt-daemon-xen was removed along with it as a dependency. Creating VM's failed again with an error during the hotplug of the vif. I decided to get a little more forceful: yum -y install libvirt-daemon-xen rpm -ev --nodeps libvirt-daemon-driver-libxl I restarted the libvirtd daemon and now I'm creating VM's without any errors. Am I alone on this one? I was about to pop something in Bugzilla for it but I figured I'd ask the list just in case. If this belongs on the fedora-virt list, please throw a large piece of furniture in my general direction and I'll try to remember next time. ;) -- Major Hayden

Updating xen package does not 'refresh' grub.cfg
by Dario Faggioli 19 Feb '13

19 Feb '13

Hello, I just noticed that he thing described in the subject happens, when I 'yum upgrade' both a F18 or a rawhide system, and when the updates include a new version of xen-XXX. In some more details, what I noticed is after doing the following: - yum upgrade, and the upgrade included a new version of xen-xxx - reboot and choose 'Fedora with Xen Hypervisor' Makes the system no longer able to boot. Just booting another option, executing manually `grub2-mkconfig -o /boot/grub/grub.cfg' and rebooting again did the trick. So, it looks like, while installing the xen package for the first time correctly creatte the GRUB2 menu entry, updating it does not properly refreshes it. Is this happening only to me? Is this intended/supposed to happen? If so, sorry for bothering. :-) If no, let me know if I should file a bug, or whatever else I can do to help fixing this. Thanks and Regards, Dario -- <<This happens because I choose it to happen!>> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://retis.sssup.it/people/faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK)

f18, xen, utils
by Mike Wright 17 Feb '13

Hi all, "rpm -qlp xen-4.2.1-5.fc18.x86_64.rpm" yields quite a surprise. There is no trace of xl. The package still includes xm which requires xend, both of which have been deprecated since (I think) xen 4.0.0. Granted, I built, rather than yummed, 4.0.0 from sources and have been using xl ever since but the continued distribution of xm confuses me greatly. Two questions: Does anybody know why this was done? Is there a package that includes xl? This is extremely frustrating. I've been waiting years for a mainline kernel that includes Dom0/DomU and PCI-passthrough support and now that it is available I still have to build xen from scratch to get the new xl tool stack that was introduced many versions ago. Thanks for any insight, tips. Mike Wright
