| === Enterprise Management Tools List ===
| |
| This section contains the discussion happening on the [https://www.redhat.com/mailman/listinfo/et-mgmt-tools et-mgmt-tools list]
| |
| | |
| ==== Maximum Number of Attached CDROMs in Xen ====
| |
| [[AlexanderTodorov|Alexander Todorov]] asked[1] why only 3 CDROM devices could
| |
| be attached in <code>virt-manager</code>.
| |
| | |
| [[ColeRobinson|Cole Robinson]] replied[2] "Xen uses a forked qemu for HVM device emulation" and the version on RHEL is limited to 4 IDE devices.
| |
| The newer <code>qemu</code> found in Fedora 9 allow attaching SCSI disks and CDROMs, and thereby more devices. This ability already in <code>libvirt</code> is not yet exposed in the <code>virt-manager</code> GUI.

| ==== [PATCH] virtinst - virt-convert VMWare VMX Output ====
| |
| [[JoeyBoggs|Joey Boggs]] posted[1] a patch which provides VMWare vmx[2] output
| |
| from <code>virt-convert</code>. "This will replace the virt-pack command and supplemental Unware.py file and integrate them into virt-convert directly as a module."

| ==== Continued Trouble with 32bit Fedora 9 DomU on Fedora 8 Dom0 ====
| |
| [[FredBrier|Fred Brier]] followed[1] up on a thread[2] from June 2008. It
| |
| seems that on a 32bit system running Fedora 8 dom0, the shutdown or restart of
| |
| a Fedora 9 domU results in that guest being inaccessible to libvirt tools
| |
| until a dom0 reboot or xend restart. There are at least two similar bugs[3],[4] filed for this issue.

| ==== Libvirt 0.4.6 Released ====
| |
| [[DanielVeillard|Daniel Veillard]] announced[1] the release of <code>libvirt</code> 0.4.6. "There is no major change in this release, just the bug fixes a few
| |
| improvements and some cleanup".
| |
| | |
| Improvements include:
| |
| * add storage disk volume delete (Cole Robinson)
| |
| * KVM dynamic max CPU detection (Guido Günther)
| |
| * spec file improvement for minimal builds (Ben Guthro)
| |
| * improved error message in XM configuration module (Richard Jones)
| |
| * network config in OpenVZ support (Evgeniy Sokolov)
| |
| * enable stopping a pool in logical storage backend and cleanup deletion of pool (Chris Lalancette)

| | |
| After finding no F8 build newer than 0.4.4 in [[Bodhi Guide|Bodhi]], [[DaleBewley|Dale Bewley]] asked[2] if the Xen users stuck[3] on Fedora 8 could expect an update[4].
| |
| | |
| [[DanielVeillard|Daniel Veillard]] responded[5] it was unclear the release would fix anything for Xen users and "It was looking more risky than potentially useful to update there."

| [[DavidLively|David Lively]] began[1] a discusion on implementation of events in libvirtd.

| ==== Windows Binaries ====
| |
| [[RichardJones|Richard W.M. Jones]] pointed[1] out that -- while not an official distribution -- binaries for <code>libvirt-0.dll</code> and <code>virsh.exe</code> are available[2] in the <code>mingw32-libvirt</code> package.

| === oVirt Devel List ===
| |
| This section contains the discussion happening on the [https://www.redhat.com/mailman/listinfo/ovirt-devel ovirt-devel list].
| |
| | |
| ==== oVirt 0.93-1 Released ====
| |
| [[PerryMyers|Perry N. Myers]] [1]
| |
| | |
| both the oVirt Node and oVirt Server Suite.
| |
| | |
| New features in this release include:
| |
| * Addition of 'Smart Pools' in the Web user interface for organizing pools on a per user basis.
| |
| * Additions to the Edit VM screen to allow re-provisioning of a guest as well editing other guest settings.
| |
| * oVirt Appliance manages VMs directly on the host it is running on. This eliminates the 'fake nodes' used in previous versions.
| |
| * oVirt API (Ruby Bindings)
| |
| * Support for configuring more than one NIC per Node. UI support for this will be integrated shortly.
| |
| * Support for bonding/failover of NICs. UI support for this will be integrated shortly.
| |
| * SELinux support on oVirt Node
| |
| * Rewrite of performance graphing visualization
| |

| ==== Modeling LVM Storage ====
| | Contributing Writer: [[User:Dale | Dale Bewley]] |
| [[ChrisLalancette|Chris Lalancette]] described[1] the outcome of a IRC chat | |
| about carving up storage with LVM.
| |
|
| |
|
| The existing StoragePool in the current model contains zero or more StorageVolumes. Chris described adding a StorageVolume of type LVM which contains one or more iSCSI StorageVolumes and presumably fiberchannel in the future.
| | === Fedora Virtualization List === |
| | This section contains the discussion happening on the |
| | [http://www.redhat.com/mailman/listinfo/fedora-virt fedora-virt list]. |
|
| |
|
| After the model is modified and the backend "taskomatic" code is in place, then while provisioning a guest VM the user will either choose an entire LUN guest, choose an existing logical volume, or create a new volume.
| | ==== Virt Status Report ==== |
| | [[JustinForbes|Justin Forbes]] |
| | 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. |

| [[ScottSeago|Scott Seago]] clarified[2] that "volumes must be of the same 'type' as the pool". An IscsiStoragePool contains IscsiStorageVolumes an LvmStoragePool contains LvmStorageVolumes. "In additon, for LvmStoragePools, we have a new association defined between it and StorageVolumes. an LvmStoragePool has 1 or more "source storage volumes""... "which for the moment must be IscsiStorageVolumes."
| | ==== 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. |
|
| |
|
| "When determining which storage volumes are available for guests, we'll have to filter out storage volumes which are connected to LvmStoragePools." | | [[DanielBerrange|Daniel Berrange]] |
| | 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 |
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| | also pretty close to that using what's best described as a hybrid of |
| | kvm-83 and kvm-84." |

|
| [[SteveOfsthun|Steve Ofsthun]] asked[3] how will oVirt distinguish between logical volumes created
| |
| on a whole disk assigned to a guest versus volumes used by the host.
| |
| [[DanielBerrange|Daniel P. Berrange]] suggested[4] this could accomplished by creating a partition on the disk and assigning this to
| |
| the guest, thereby making the guest LVM one step removed from the host.
