The final change deadline is currently 26th November. That may not be an absolute deadline, but you have a better chance of the libvirt team accepting changes before then. Michael Young

Xen install test: On Fedora 17, install Fedora 17. Mouse problem?
by Marko Ristola 31 Oct '12

31 Oct '12

Hi I don't have a bugzilla report item from this yet, maybe later. I have now Xen Dom0 Fedora 17 configuration, no experimental packages. Desktop computer is rather new and supports hardware virtualization, but not IOMMU. Test: Install paravirtual 64 bit Xen guest, Fedora 17 with HTTP based install. - With Virt-manager installing went flawlessly. - After reboot, I got in Finnish with a graphical picture: "Voi ei! Jotain meni pieleen". This means "Oh no, something got wrong." So it seems that GDM doesn't work with Xen with default virt-manager settings. - I can make Login screen by switching from GDM to KDM. Mouse works there: /etc/sysconfig/desktop: DISPLAYMANAGER=KDE - From KDM I can start Gnome. Mouse works but Mouse cursor is invisible. - If I start, via KDM, IceWM, mouse works and is visible. I don't know if Fedora 18 will have this issue too. It would be nice if Fedora as Dom0 would just work for Fedora Xen DomU with default options. Maybe plain AbsoluteAxis for paravirtual mouse would be the best option, no relative axis enabled by default? Maybe co-operation with Gnome people is needed to finish this issue?

Call for Participation to the Fedora Virt Test Day
by Dario Faggioli 31 Oct '12

31 Oct '12

As usual, the Fedora community has planned a number of Test Days for the upcoming 18 release, including include a Virtualization Test Day on November 1st (this Thursday): https://fedoraproject.org/wiki/Test_Day:2012-11-01_Virtualization We are therefore calling all our community members to participate in the test day as much as possible. Specific information regarding testing Xen on Fedora can be found in this Wiki page: http://wiki.xen.org/wiki/Fedora_Test_Days For participating, or just if attending, be sure you hang out on IRC at #fedora-test-day (on Freenode) on Thursday ! Fedora 18 will be one of the first distros shipping Xen 4.2... So come and help us making sure it will work great for all users !! 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)

Fwd: [fedora-virt] Fedora 18 Virt Test Day is Thurs Nov 1, we need you!
by Cole Robinson 31 Oct '12

31 Oct '12

Hey all, In case you aren't subscribed to the virt@ list, here's what I just sent there. Though most of the info below pertains to KVM, I encourage all Xen users/devs to show up, so feel free to stick your names on the fedora wiki page. More virt and Fedora 18 testing is better for everyone :) And as mentioned in Dario's earlier mail, check out his excellent xen focused page here: http://wiki.xen.org/wiki/Fedora_Test_Days Thanks, Cole -------- Original Message -------- Subject: [fedora-virt] Fedora 18 Virt Test Day is Thurs Nov 1, we need you! Date: Tue, 30 Oct 2012 16:52:58 -0400 From: Cole Robinson <crobinso(a)redhat.com> To: Fedora Virt <virt(a)lists.fedoraproject.org> Hey all, The Fedora 18 Virt Test Day is this Thursday, November 1st. That's two days away! The test day landing page is here: https://fedoraproject.org/wiki/Test_Day:2012-11-01_Virtualization If you're interested in trying out some new virt functionality, we've got step by step instructions for: * Using snapshots to backup disk images of a live VM with no VM downtime * Assigning a physical USB3 device to your VM * Assign a local USB device to your VM, even if the VM is on a remote machine! * Setting disk IO bandwidth limits on your VM * Suspend and Hibernate your VMs * Enabling the PV EOI performance optimization for your VMs * Using kernel syscall filters (seccomp) to further secure your host against VM exploits (currently busted but we are working on a fix) Of course, maybe you don't care about new features. We still need you! The test day is the perfect time to make sure your virt workflow is working fine on Fedora 18, as there will be several developers on hand to answer any questions, help with debugging, provide patches, etc. No requirement to run through test cases on the wiki, just show up and let us know what works (or breaks). And to be clear, while it is greatly preferred that you have a physical machine running Fedora 18, participating in the test day does NOT require it: you can test the latest virt bits on Fedora 17 courtesy of the virt-preview repo. For more details, as well as easy instructions on updating to Fedora 18, see: https://fedoraproject.org/wiki/Test_Day:2012-11-01_Virtualization#What.27s_… If you plan on showing up to the test day, add your name to the participant list on the wiki, and on thursday, pop into #fedora-test-day on freenode and give us a shout!

What I'm not sure about is whether or not that could also happen _after_ the release. IOW, would such an update to libvirt hit the already released F18?

Xen 4.2 in rawhide
by M A Young 26 Oct '12

26 Oct '12

Xen has been updated to version 4.2.0 in rawhide. To get this to work Cole Robinson has disabled libxl support in libvirt because libvirt doesn't yet support the 4.2 updates to libxl. There should still be time to get xen 4.2 into Fedora 18 if there aren't any problems in rawhide. Michael Young
