==== 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.

==== Parallel Port Support in virt-manager ====
[[BobTennent|Bob Tennent]] asked if <code>virt-manager</code> supports adding
a parallel port to a guest OS. [[ColeRobinson|Cole Robinson]] answered[2] this
functionality is[3] in <code>libvirt</code>, but not exposed in <code>virt-manager</code> yet.

==== VMWare VMX Output from virt-convert  ====
[[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."

==== Disk Image Signature Verification ====
[[JoeyBoggs|Joey Boggs]] posted patches for <code>virtinst</code>[1] and for <code>virt-convert</code>[2] that "will add in disk signature support for ISV's and others folks that wish to verify the disk has not been altered prior to running virt-image. Supports MD5 and SHA1 signatures."

==== 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."

==== RFC: Events API ====
[[DavidLively|David Lively]] began[1] a discusion on implementation of events in libvirtd.
[1] https://www.redhat.com/archives/libvir-list/2008-September/msg00321.html
==== 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 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 ====
[[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.
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.
[1] https://www.redhat.com/archives/ovirt-devel/2008-September/msg00313.html
[[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."
"When determining which storage volumes are available for guests, we'll have to filter out storage volumes which are connected to LvmStoragePools."
[2] https://www.redhat.com/archives/ovirt-devel/2008-September/msg00315.html
[[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.
