| ==== Starting Guests from a Desktop Icon ====
| |
| [[OrionPoplawski|Orion Poplawski]] said[1]
| |
| "I'd like to provide an icon that would startup the virtual machine and connect to it."
| |
| [[ColeRobinson|Cole Robinson]] posted[2] a couple of ways to accomplish this.
| |
| | |
| * With <code>virt-manager</code> and support for CDROM and USB devices
| |
| <pre>
| |
| UUID=`virsh --connect qemu:///system domuuid vm-name`
| |
| virsh --connect qemu:///system start $UUID
| |
| virt-manager --connect qemu:///system \
| |
| --show-domain-console=$UUID
| |
| </pre>
| |
| | |
| * With <code>virt-viewer</code> which won't support CDROM and USB access
| |
| <pre>
| |
| UUID=`virsh --connect qemu:///system domuuid vm-name`
| |
| virsh --connect qemu:///system start $UUID
| |
| virt-viewer --connect qemu:///system $UUID | |
| </pre>
| |
| | |
| Each solution requires adequate user permissions to work.

| ==== Openvz Bridge Support and Related Patches ==== | | === Fedora Virtualization List === |
| "This patch series is derived from Anton Protopopov /Evgeniy Sokolov
| | This section contains the discussion happening on the |
| bridge device patches. It first does some generic refactoring of MAC
| | [http://www.redhat.com/mailman/listinfo/fedora-virt fedora-virt list]. |
| address handler in all drivers, then adds code to extract openvz version
| |
| number, then does network config, and finally does filesystem config.

| ==== Image Locking ====
| | <references /> |
| [[ItamarHeim|Itamar Heim]] [1]
| |
| "I am interested to find out how libvirt envisions image locking. i.e., how do we make sure multiple nodes are not trying to access the same storage volume, probably causing image corruption."...

| | ==== 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. |

| ==== Export the 'label' on Block Devices ====
| | [[DanielBerrange|Daniel Berrange]] |
| [[ChrisLalancette|Chris Lalancette]] [1] | | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |
| "To support LVM partitioning in oVirt, one of the things we need is the ability | | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| to tell what kind of label is currently on a block device. Here, a 'label' is
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| used in the same sense that it is used in parted; namely, it defines which kind
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| of partition table is on the disk, whether it be DOS, LVM2, SUN, BSD, etc. Note
| | also pretty close to that using what's best described as a hybrid of |
| that this is different than the partition type; those are things like Linux, | | kvm-83 and kvm-84." |
| FAT16, FAT32, etc."...

| ==== Experimental User Mode Linux Driver ====
| |
| [[DanielBerrange|Daniel P. Berrange]] [1]
| |
| "This patch implements a driver supporting User Mode Linux guests. User mode
| |
| linux is a kind of paravirtualized kernel which runs on a plain Linux host.
| |
| It requires no elevated privileges at all, except for some of the network
| |
| integration. It is a pretty straightforward thing to invoke, so I figured
| |
| it would be easy to write a driver to support it. I was right :-)"...
