| === Enterprise Management Tools List ===
| |
| This section contains the discussion happening on the

| ==== New Release virt-manager 0.7.0 ====
| |
| [[ColeRobinson|Cole Robinson]] announce<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-March/msg00058.html</ref>
| |
| a new {{package|virt-manager}}<ref>http://virt-manager.org/</ref> release, version 0.7.0.
| |
|
| |
| Virtual Machine Manager provides a graphical tool for administering virtual
| |
| machines for <code>KVM</code>, <code>Xen</code>, and <code>QEmu</code>. Start, stop, add or remove virtual devices,
| |
| connect to a graphical or serial console, and see resource usage statistics
| |
| for existing VMs on local or remote machines. Uses {{package|libvirt}} as the backend
| |
| management API.
| |
|
| |
| '''New features:'''
| |
| * Redesigned 'New Virtual Machine' wizard (Jeremy Perry, Tim Allen, Cole Robinson)
| |
| * Option to remove storage when deleting a virtual machine.
| |
| * File browser for libvirt storage pools and volumes, for use when attaching storage to a new or existing guest.
| |
| * Physical device assignment (PCI, USB) for existing virtual machines.
| |
| * Bug fixes and minor improvements.

| ==== New Release virtinst 0.4.3 ====
| |
| [[ColeRobinson|Cole Robinson]] announce<ref>http://www.redhat.com/archives/et-mgmt-tools/2009-March/msg00057.html</ref>
| |
| a new {{package|python-virtinst}} release, version 0.400.3.
| |
|
| |
| <code>virtinst</code> is a module that helps build and install <code>libvirt</code> based virtual
| |
| machines. It currently supports <code>KVM</code>, <code>QEmu</code> and <code>Xen</code> virtual machines. Package
| |
| includes several command line utilities, including <code>virt-install</code> (build
| |
| and install new VMs) and <code>virt-clone</code> (clone an existing virtual machine).
| |
|
| |
| This is largely a bug fix release.

| ==== Serial Console Support in virt-manager ==== | | ==== Virt Status Report ==== |
| Jan ONDREJ tested<ref>http://www.redhat.com/archives/fedora-virt/2009-March/msg00028.html</ref> the new {{package|virt-manager}} 0.7.0 on Fedora 10, and had some suggestions.
| | [[JustinForbes|Justin Forbes]] |
| | | posted<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00056.html</ref> a Fedora virtualization status report. |
| {{Admon/note|TODO}}
| | 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. |
| | |
| <pre>
| |
| Starting an domain starts my serial console owned by root and is not
| |
| accesssible from virt-manager (virt-viewer). After changing ownership it's
| |
| immediatelly available. Is it possible to change this in time of virtual
| |
| machine creation? (in libvirt or where?)
| |
| | |
| Another feature enhacement can be adding "Serial 0" tab automatically,
| |
| when there is no Console available for guest. Message "Console not
| |
| configured for guest" can be sometimes misinterpretated, because I can have
| |
| serial console for my guest. I prefer to use serial consoles, because they
| |
| do not need to install graphical environment on host. They have multiple
| |
| advantages, like access from another machine using serial or ipmi console,
| |
| viewing crash status, when host crashes, ...
| |
| | |
| And last possible enhancement: when pressing F10 key in guest's serial
| |
| console, is it possible to avoid opening of "File menu" and send this key to
| |
| serial 0, as it is done in VGA console?

| |
| Yes, this is one of the drawbacks of not running virt-manager as root:
| |
| since the qemu:///system libvirt connection will launch your guests as
| |
| root, a regular user won't be able to access ptys.
| |
| | |
| I don't know of a proper solution to it all, other then running the app
| |
| as root or changing the the pty permissions as you did.

| |
| | |
| I see what you mean. The wording could certainly be better, and It would
| |
| make sense to try to connect to the serial console if no graphics device
| |
| is attached. Thanks for the idea.

| We would probably need some sort of keygrab process like we do for VNC
| |
| to get this right. Not sure if that's even an option for the VTE widget
| |
| though.

| === Fedora Xen List === | | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| This section contains the discussion happening on the
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| [http://www.redhat.com/mailman/listinfo/fedora-xen fedora-xen list].
| | compared to Fedora 12. |
| | |
| ==== dom0 Kernel: Better, Still Not Ready ====
| |
| Itamar Reis Peixoto reported<ref>http://www.redhat.com/archives/fedora-xen/2009-March/msg00046.html</ref>
| |
| success with [[MichaelYoung|Michael Young]]'s latest {{package|kernel}} build<ref>http://koji.fedoraproject.org/koji/taskinfo?taskID=1238587</ref> and wondered when it could be released.
| |
| | |
| Michael explained, "The current plan is to wait until basic <code>dom0</code> support makes it into the vanilla <code>kernel</code>, which should happen for 2.6.30, and then decide if <code>dom0</code> can be enabled and if the patches for full <code>dom0</code> support can safely be added without affecting ordinary operation."
| |
|
| |
|
| "At the moment there are still things that are broken such as <code>X</code> support in some cases, and there are also Fedora patches that have been omitted because they were tricky to merge, so it is too early to start adding <code>dom0</code> support to official Fedora kernels."
| | [[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." |

| ==== Missing Hypervisor Capabilities Restored ====
| |
| There was progress on a bug discovered<ref>http://fedoraproject.org/wiki/FWN/Issue166#dom0_Kernel_Inches_Closer</ref> last week. This missing file
| |
| <code>/sys/hypervisor/properties/capabilities</code> has been
| |
| restored<ref>http://www.redhat.com/archives/fedora-xen/2009-March/msg00039.html</ref>,
| |
| however a bug<ref>https://bugzilla.redhat.com/show_bug.cgi?id=489799</ref> remained<ref>http://www.redhat.com/archives/fedora-xen/2009-March/msg00040.html</ref> in <code>libvirt</code> or <code>virt-install</code>.
