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. You can tweak the Xen hypervisor cmdline options in: /etc/default/grub file, like this: GRUB_DEFAULT=Xen The only thing I see in fc17 (also) is a set default=Xen line in /boot/grub2/grub.cfg I've been waiting, hoping, and did a fresh install of Fedora 17, then yum install xen, in anticipation (again) of Fedora/Xen/dom0 boot magic. Disappointment. And did you run grub2-mkconfig -o /boot/grub2/grub.cfg ? What's the problem? -- Pasi -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen

Re: [Fedora-xen] [Xen-users] provisioning virtual machine
I have a master virtual machine and I want copy it to other systems and deploy it. I dont want to copy the whole image as it is too big. What are my options here?

Can we transfer a LVM virtual machine image? You can use *all* the normal Linux/unix tools, Xen doesn't create any restrictions there. So feel free to dd the volume to another volume, or use snapshots, or thinprov-snapshots, or whatever you want. -- Pasi On Thu, Jun 28, 2012 at 4:26 PM, Pasi Kärkkäinen [1]pa...@iki.fi wrote: On Wed, Jun 27, 2012 at 05:51:13PM +0200, Arindam Choudhury wrote: I am using xen hypervisor in fedora 17.

Re: [Fedora-xen] Python misbehaves on Xen/Fedora 17/AMD FX-4170 Processor

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.
