| | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| | compared to Fedora 12. |
|

|
| ==== New virt-inspector Features ====

| announced<ref>http://www.redhat.com/archives/fedora-virt/2009-June/msg00049.html</ref>
| | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| | | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| "I've added a few extra features to virt-inspector<ref>http://et.redhat.com/~rjones/libguestfs/virt-inspector.1.html</ref> (in | | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| {{package|libguestfs}}<ref>http://et.redhat.com/~rjones/libguestfs/</ref> >= 1.0.42)." | | also pretty close to that using what's best described as a hybrid of |
| | | kvm-83 and kvm-84." |
| "First up is a new 'query mode'"
| |
| which prints "out some useful facts about the virtual machine such
| |
| as whether it's fully virtualized or needs a Xen hypervisor, and
| |
| whether it has various paravirt drivers installed."
| |
| | |
| "Secondly (not covered in the manpage), virt-inspector will try to
| |
| discover whether a VM contains the right initrd drivers and module
| |
| configuration to boot under various hypervisors. So for example it
| |
| can tell you whether a guest has the virtio drivers available at boot
| |
| time to boot from a virtio disk."

| ==== Fedora Virtualization Status ====
| |
| [[MarkMcLoughlin|Mark McLoughlin]]
| |
| looked<ref>http://www.redhat.com/archives/fedora-virt/2009-June/msg00030.html</ref> on to Fedora 12 in his latest virtualization status report.
| |
| "Okay, so F-11 is done and dusted. Onwards to F-12!" "Here's what the schedule looks like:"
| |
| : 2009-07-28 Feature Freeze (53 days)
| |
| : 2009-08-04 Beta Freeze (60 days)
| |
| : 2009-09-22 Final Development Freeze (109 days)
| |
| : 2009-10-20 Compose & Stage Release Candidate (137 days)
| |
|
| |
| Highlights of the report included:
| |
| * A thorough run-down of virtualization related bugs.
| |
| * "Dan Berrange was interviewed about virtualization in Fedora 11."<ref>http://jaboutboul.blogspot.com/2009/05/fedora-11-virtualization-reality.html</ref>
| |
| * "Updates are being pushed regularily to the virt-preview repository"<ref>http://markmc.fedorapeople.org/virt-preview/README</ref>
| |
| * "Jeremy Fitzhardinge's latest submission of the Xen Dom0 patches for
| |
| 2.6.31 has caused the kernel community to get themselves into a bit of
| |
| a flap. LWN has a nice article on the 'discussion'"<ref>http://lwn.net/Articles/335812/</ref>
| |
|
| |
| [[GerdHoffmann|Gerd Hoffmann]]
| |
| followed<ref>http://www.redhat.com/archives/fedora-virt/2009-June/msg00034.html</ref>
| |
| up with some details on the controversial bits.
| |
| "lapic + ioapic. That is the big hot topic. Current code lacks
| |
| sensible interfaces to the different apic types out there in the
| |
| wild. The current dom0 patches hook just into that mess instead
| |
| of cleaning it up. Right now it looks like Jeremy has to sort
| |
| that mess to get the xen bits in, using the to-be-created apic
| |
| interfaces."
| |
|
| |
| "No way the apic stuff will make it into the 2.6.31 merge window opening RSN, the work on that barely started. Thus we can expect functional dom0 support upstream in 2.6.32 earliest."
| |
|
| |
| "Also noteworthy: There is a discussion on xen-devel regarding the future of the xen linux trees. Which one should be used & maintained and so on."
| |
| "Looks like Keir seriously considers switching xen-unstable to the pv_ops kernel by default. YES! FINALLY! Well, it is probably to early to uncork the champagne, but I think we can at least put a bottle into the fridge ;)"
