| ==== Guest Bridge Configuration with libvirt and netcf ==== | | ==== Virt Status Report ==== |
| [[AndrésGarcía|Andrés García]] | | [[JustinForbes|Justin Forbes]] |
| thought<ref>http://www.redhat.com/archives/fedora-virt/2009-November/msg00002.html</ref> he read somewhere that with [[Releases/12|Fedora 12]] there was going to be a way to configure virtual network bridges automagically", but was only aware of the manual<ref>http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared_physical_device.22.29</ref> means of configuration.
| | posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report. |
| | | Justin pointed out F13 bugs<ref>http://fedoraproject.org/wiki/Virtualization_bugs</ref> now include Important and Pony classifications in addition to Blocker and Target. |
| It is possible in to configure bridges using <code>virsh</code> thanks to the Network Interface Management<ref>http://fedoraproject.org/wiki/Features/Network_Interface_Management</ref> feature and {{package|netcf}}<ref>http://linux-kvm.com/content/netcf-silver-bullet-network-configuration</ref>. However, the process is manual and not in the GUI. [[DaleBewley|Dale Bewley]] blogged<ref>http://tofu.org/drupal/node/86</ref> about how to manually create a bridge in Fedora 12 using <code>virsh</code>.
| |
| | |
| Support for {{package|virt-manager}} integration is targeted<ref>http://fedoraproject.org/wiki/Features/Shared_Network_Interface</ref> for Fedora 13.

| ==== New Release libguestfs 1.0.78 ==== | | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| [[RichardJones|Richard Jones]] announced<ref>http://www.redhat.com/archives/virt-tools-list/2009-November/msg00023.html</ref>
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| version 1.0.78 of {{package|libguestfs}}<ref>http://libguestfs.org/</ref>, the library for accessing and modifying virtual machine filesystems.
| | compared to Fedora 12. |
|
| |
|
| '''New Features:'''
| | [[DanielBerrange|Daniel Berrange]] |
| * FUSE support so you can mount guest filesystems in the host <ref>http://rwmj.wordpress.com/2009/11/03/browsing-guests-using-fuse/</ref>
| | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |

| | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| * Support for huge (multi-exabyte) sparse virtual disks<ref>http://rwmj.wordpress.com/2009/11/04/petabytes-exabytes-why-not/</ref>
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| * New partitioning API, supports GPT and more<ref>http://libguestfs.org/guestfs.3.html#guestfs_part_add</ref>
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| * New tools:
| | also pretty close to that using what's best described as a hybrid of |
| :* <code>virt-ls</code><ref>http://rwmj.wordpress.com/2009/10/19/new-tool-virt-ls/</ref>
| | kvm-83 and kvm-84." |
| :* <code>virt-tar</code><ref>http://rwmj.wordpress.com/2009/10/19/new-tool-virt-tar/</ref>

| ==== No Xen dom0 in Fedora 12 Hopefully 13 ====
| |
| [[ZhangEnming|Zhang Enming]]
| |
| was disappointed<ref>http://www.redhat.com/archives/fedora-xen/2009-November/msg00019.html</ref> to learn<ref>http://fedoraproject.org/wiki/Docs/Beats/Virtualization</ref> the pv_ops dom0 support<ref>http://fedoraproject.org/wiki/Features/XenPvopsDom0</ref> for hosting Xen guests, dropped in Fedora 9, is still not present in Fedora 12.
| |
| Zhang referenced numerous videos documenting success in creating "a fully working Xen pv-ops dom0 Fedora 11 host operating system."
| |
|
| |
| While there are experimental patches which may be applied<ref>http://fedoraproject.org/wiki/FWN/Issue190#Dom0_Kernel_Status</ref> <ref>http://wiki.xensource.com/xenwiki/XenParavirtOps</ref> to the kernel to enable support for dom0, they are not yet in the upstream kernel which forms the basis the Fedora kernel package.
| |
|
| |
| It was decided<ref>http://www.redhat.com/archives/fedora-xen/2007-November/msg00106.html</ref> two years ago this month that
| |
| Fedora "simply cannot spend more time forward porting Xen kernels" and
| |
| "the plan is to re-focus 100% of all Xen kernel efforts onto paravirt_ops."
| |
| See FWN#137.<ref>http://fedoraproject.org/wiki/FWN/Issue137#kernel-xen_is_Dead</ref>

| [[PasiKärkkäinen|Pasi Kärkkäinen]]
| |
| noted<ref>http://www.redhat.com/archives/fedora-xen/2009-November/msg00020.html</ref>
| |
| "pv_ops dom0 kernel has only recently started working for many/most
| |
| people, so it was too late for F12 release" and
| |
| "There are still some missing features, most notably missing blktap2 support
| |
| for tap:aio: file-based images."
