| ==== KVM and QEMU Merge Feature Stays in Fedora 11==== | | ==== Virt Status Report ==== |
| After missing the previous

| round (FWN #165<ref>http://fedoraproject.org/wiki/FWN/Issue165#Approved_F11_Virtualization_Features</ref>)
| | posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report. |
| and some development delay, the <code>KVM</code> and <code>QEMU</code> package merge
| | 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. |
| feature<ref>http://fedoraproject.org/wiki/Features/KVM_and_QEMU_merge</ref>
| |
| of Fedora 11 has been marked as
| |
| accepted by the Fedora Engineering Steering Committee<ref>http://fedoraproject.org/wiki/FESCO</ref>.
| |
| | |
| "Currently, there is both a {{package|qemu}} package and {{package|kvm}} package. The <code>KVM</code> package's source is a fork of the <code>QEMU</code> source, but <code>KVM</code> regularily re-bases to the latest <code>QEMU</code> source and merging of <code>KVM</code> support into the <code>QEMU</code> code base is actively under-way."

| ==== Success with Experimental Fedora 10 pv_ops dom0 ====
| |
| Users are continuing to build experimental kernels with <code>pv_ops</code> dom0<ref>http://fedoraproject.org/wiki/Features/XenPvopsDom0</ref> support.
| |
| [[PasiKärkkäinen|Pasi Kärkkäinen]]
| |
| was happy to
| |
| report<ref>http://www.redhat.com/archives/fedora-xen/2009-March/msg00071.html</ref> | |
| success getting a
| |
| "custom Xen <code>pv_ops</code> dom0 <code>kernel</code> working with
| |
| <code>virt-install</code> and/or {{package|virt-manager}} on Fedora 10".
| |
| | |
| "I was able to run the following on Fedora 10 32bit PAE pv_ops dom0:"
| |
| * CentOS 5.3 32bit PAE PV domU
| |
| * Fedora 10 32bit PAE PV domU (using <code>virt-install</code> and custom kickstart to force PAE kernel installation to avoid the anaconda BUG<ref>https://bugzilla.redhat.com/show_bug.cgi?id=470905</ref>)
| |
| | |
| Pasi was successful by using:
| |
| * pv_ops dom0 kernel (2.6.29-rc8 or newer) "Compile with <code>CONFIG_HIGHPTE=n</code> since it seems to be broken still"
| |
| * {{package|libvirt}} 0.6.1 and related packages from Fedora 10 updates-testing
| |
| * {{package|xen}} 3.3.1-9 packages from rawhide/F11 rebuilt for F10
| |
| * LVM volumes for domU disks (<code>tap:aio</code> is not yet supported by <code>pv_ops</code> dom0 kernel)

| ==== More Formal libvirt Release Scheduling ====
| |
| After
| |
| [[DanielVeillard|Daniel Veillard]]
| |
| proposed a {{package|libvirt}} 0.6.2 release next week,
| |
| [[DanielBerrange|Daniel Berrange]]
| |
| thought
| |
| <ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00435.html</ref>
| |
| the "release schedule has become a little too variable in timeframe and
| |
| quality in recent times."
| |
| (FWN #155<ref>http://fedoraproject.org/wiki/FWN/Issue155#Release_of_libvirt_0.5.0_and_0.5.1</ref>) and suggested
| |
| * Monthly releases aiming for the 1st of the month.
| |
| * Any non-trivial new feature for release must be reviewed, approved and committed at least 1 week before the release.
| |
| | |
| [[DanielBerrange|Daniel Berrange]] is also
| |
| "working on an integration test suite, which will
| |
| enable us to run automated tests against individual hypervisor drivers.
| |
| This will help us detect regressions in hypervisor drivers, and more
| |
| importantly let us ensure that all drivers are implementing consistent
| |
| semantics for their APIs."
| |
| | |
| [[DanielVeillard|Daniel Veillard]]
| |
| tended<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00446.html</ref>
| |
| "to agree on the approximate rule of one release every months [sic]
| |
| but I would like to keep this flexible" and offered this schedule for the
| |
| next 2 releases:
| |
| | |
| * 0.6.2:
| |
| : commit feature freeze: Tuesday 31 Mar
| |
| : expected release date: Friday 3 Apr
| |
| | |
| * 0.6.3:
| |
| : commit feature freeze: Friday 17 Apr
| |
| : expected release date: Friday 24 Apr

| ==== New Release perl-Sys-Virt 0.2.0 ==== | | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| [[DanielBerrange|Daniel Berrange]]
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| announced<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00449.html</ref>
| | compared to Fedora 12. |
| an update of the Perl binding for <code>libvirt</code>, {{package|perl-Sys-Virt}}<ref>http://search.cpan.org/dist/Sys-Virt/</ref>.
| |
|
| |
|
| '''New features:'''
| | [[DanielBerrange|Daniel Berrange]] |
| * Fix network create API, and UUID lookups
| | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |
| * Implement storage pool, storage vol, node device, security model, domain events and event loop APIs
| | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| * Improve way constants are exposed to Perl layer
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| * Fix horrible memory leak in methods returning a hash
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| * Fix integer overflow in APIs using 64-bit ints (aka 'long long')
| | also pretty close to that using what's best described as a hybrid of |
| * Minimum required libvirt C library for building is 0.6.1
| | kvm-83 and kvm-84." |

| ==== SCSI Host Pools Patch ====
| |
| [[DavidAllan|David Allan]]
| |
| has been working<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00420.html</ref>
| |
| on a reworked SCSI host storage pool<ref>http://www.libvirt.org/storage.html</ref>
| |
| patch for some time, and appears to be close to ironing out all the bugs.

| ==== API for Host Interface Configuration ====
| |
| The Shared Network Interface
| |
| feature<ref>http://fedoraproject.org/wiki/Features/Shared_Network_Interface</ref>
| |
| was deferred to Fedora 12 while
| |
| [[DavidLutterkort|David Lutterkort]]
| |
| continues to work on <code>netcf</code><ref>http://people.redhat.com/dlutter/netcf/</ref>
| |
| (FWN #164<ref>http://fedoraproject.org/wiki/FWN/Issue164#netcf_Network_Interface_Configuration_Library</ref>).
| |
|
| |
| Now [[LaineStump|Laine Stump]]
| |
| has posted<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00397.html</ref>
| |
| "a first attempt at the public API that will hook up to <code>libnetcf</code> on the <code>libvirtd</code> side."

| ==== Web Based libvirt Management ====
| |
| [[RadekHladik|Radek Hladik]] is
| |
| developing<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00402.html</ref>
| |
| "a simple web application in PHP to monitor and control VMs using libvirt."
| |
| The stateless nature of the web presents efficiency problems when each action
| |
| must call out to the <code>virsh</code> command. Radik sought advice on
| |
| picking from a list of approaches.
| |
|
| |
| [[DanielBerrange|Daniel Berrange]]
| |
| picked<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00407.html</ref>
| |
| door number two, which is to create a libvirt-aware Zend extension in C.
| |
| "A few people have expressed interest in
| |
| this idea in the past, but unforatuntely I'm not aware of anyone having
| |
| written any code for this yet. We'd very much like to see a PHP binding
| |
| for libvirt developed & happy to give advice/support to anyone attempting
| |
| this."
| |
|
| |
| [[RussellHaering|Russell Haering]]
| |
| mentioned<ref>http://www.redhat.com/archives/libvir-list/2009-March/msg00409.html</ref>
| |
| a Django (python) WebApp he's working on, called virtadmin<ref>http://trac.osuosl.org/trac/virtadmin</ref>. To bridge the stateless to stateful gap, the
| |
| "system consists of a <code>python</code> daemon used for actual <code>libvirt</code>
| |
| interaction and a separate <code>django</code> web interface that interacts with the
| |
| daemon via <code>AMF</code> over https."
| |
|
| |
| Although more of an appliance, it is also worth mentioning
| |
| oVirt<ref>http://ovirt.org/</ref>.
| |
| "oVirt is a small host image that provides libvirt service and hosts virtual
| |
| machines and a web-based virtual machine management console."
