Xen Not Displayed in Boot Menu
by sorabh hamirwasia 13 Aug '12

13 Aug '12

Hi, I have installed "Xen" on Fedora16 host using "yum install xen" command and it has been installed properly. I can see the changes in /etc/grub2.cfg file too. But when I reboot then the entry for Xen is not listed in the boot menu. On further analyzing I found that in /etc/grub.conf there is no entry related to Xen. Do we need to modify grub.conf manually ? If yes then how to do that. ? Please help me with this. -- Regards, Sorabh

4.1.3-rc2 available to test
by M A Young 23 Jul '12

23 Jul '12

Here is another 4.1.3 release candidate for testing which is temporarily available at http://koji.fedoraproject.org/koji/taskinfo?taskID=4175430 My plan is to update F17 and F16 to 4.1.3 when it is released, probably also rawhide (unless 4.2 is out by then which is unlikely). F15 will almost certainly have reached EOL by the time 4.1.3 appears, so won't be updated. Michael Young

Xen, Fedora, and UEFI Secure Boot
by Dario Faggioli 12 Jul '12

12 Jul '12

Hi everyone, First of all, apologizes if the issue has been discussed already (I joined only a couple of months ago), but I was wondering whether there already are plans on how to support that UEFI Secure Boot crazy (and I've been gentle :-P) thing from the point of view of the xen packages on Fedora. I mean, is some sort of binary signing involved? If so, are we already able to do it, or at least will we be able to take advantage of whatever Fedora will do with kernel images? Or is there something different/special we should consider? I'm not at all an expert of the matter, I was just reading about it and started wondering whether it would still be possible to have xen binary packages for Fedora (and of course for other distros too)... Some of the links I found about the subject: http://mjg59.dreamwidth.org/5552.html https://lists.ubuntu.com/archives/ubuntu-devel/2012-June/035445.html 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)

Python misbehaves on Xen/Fedora 17/AMD FX-4170 Processor
by W. Michael Petullo 03 Jul '12

03 Jul '12

I am attempting to run Xen on an AMD FX-4170 Quad-Core Processor. I have installed Fedora 17 to serve as Dom0. I am finding that Python does not run well on this configuration. Specifically, "import random" causes the Python interpreter to terminate with "Illegal instruction". This means that xend and yum will not run. I filed a bug under yum [1], but just realized that things work if I boot Fedora 17 on bare metal. Under Xen, /proc/cpuinfo reports the following flags: fpu de tsc msr pae cx8 apic cmov pat clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm constant_tsc rep_good nopl nonstop_tsc extd_apicid aperfmperf pni pclmulqdq ssse3 cx16 sse4_1 sse4_2 popcnt aes hypervisor lahf_lm cmp_legacy extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch xop fma4 perfctr_core arat cpb hw_pstate Has anyone had similar trouble?

provisioning virtual machines
by Arindam Choudhury 28 Jun '12

28 Jun '12

Hi, I am trying to provision virtual machines to create a virtual machine cluster. If I try to transfer a pre-build virtual machine, its too time consuming and hard on network. So the idea of using bootstrap or kickstart seems better. Can any body point a good tutorial how to do this? Actually I have a master image and I have to copy it on all the nodes and create virtual machines. Is there any other way to do it? Regards, Arindam

Prolbem booting domU
by Lars Bjørndal 27 Jun '12

I've installed a domU with virt-install on Fedora 16 i686. Now, maybe after some yum updates on the dom0, I can't boot it. I start it with `virsh start fedora --consol', and the output is as follows.

Re: [Fedora-xen] [fedora-virt] virt-install: not a bootable disk on VM creation
