| ==== Support for Fedora 10 DomU on F8 Dom0 ====
| |
| The changes[1] made to the {{package|kernel}} which obviated
| |
| {{package|kernel-xen}} caused {{package|python-virtinst}} to fail[2] during the
| |
| creation of a Fedora 10 Xen guest on a Fedora 8 Xen host.
| |
| | |
| [[ColeRobinson|Cole Robinson]] announced[3] a test build[4] which fixes this

| ==== Paravirt Ops Dom0 Feature Update ====
| |
| After some prompting[1] from [[PasiKärkkäinen|Pasi Kärkkäinen]]
| |
| the dom0 support feature page[2] was updated to better clarify where the work
| |
| to bring dom0 support back to Fedora is being done, and to more accurately represent the current status.
| |
| | |
| The patches[3] are being written by Jeremy Fitzhardinge and others at Citrix/XenSource are being submitted to the mainline <code>kernel</code>. Once accepted in the upstream <code>kernel</code>, efforts will resume within Fedora to make the changes necessary to support dom0. These efforts include[4] ensuring the hypervisor supports <code>bzImage</code> kernels.

| ==== Release of libvirt 0.5.0 and 0.5.1 ====
| |
| [[DanielVeillard|Daniel Veillard]] announced[1][2] the releases of
| |
| {{package|libvirt}} 0.5.0 and 0.5.1. "This is a long expected release, with a lot of new features, as a result the small version number is increased." Tarballs and signed RPMs available upstream[3] and in Bodhi[4].
| |
| | |
| "As stated there is a huge amount of new features and improvement in this release, as well as a lot of bug fixes, the list is quite long". See the post[1] for the full list including the numerous improvments, documentation updates, bug fixes, and cleanups omitted below.
| |
| | |
| '''New features:'''
| |
| * CPU and scheduler support for LXC (Dan Smith)
| |
| * SDL display configuration (Daniel Berrange)
| |
| * domain lifecycle event support for QEmu and Xen with python bindings (Ben Guthro and Daniel Berrange)
| |
| * KVM/QEmu migration support (Rich Jones and Chris Lalancette)
| |
| * User Mode Linux driver (Daniel Berrange)
| |
| * API for node device enumeration using HAL and DeviceKit with python bindings (David Lively)
| |
| | |
| "Thanks a lot to everybody who contributed to this release, it is
| |
| really great to see new people providing significant patches, and the
| |
| amount of feedback received on the list."

| |
| | |
| [2] "This is actually a bug in QEMU. It should never block the VM when
| |
| the serial port buffer fills up. Unfortunately when the serial port
| |
| was connected to a TTY, QEMU would block on the write :-( The recent
| |
| KVM releases fix this, but QEMU goes years without a release so
| |
| it still suffers from this. I'd recommend filing a bug against QEMU
| |
| in your distro."

| | |
| ==== Allow Automatic Driver Probe for Remote TCP Connections ====
| |
| Later described by the release of {{package|libvirt}} 0.5.1 as an improvement, [[DanielBerrange|Daniel P. Berrange]] posted[1] the patch to implement a more general method for connecting to remote[2] hypervisor drivers.
| |
| | |
| "When connecting to a local <code>libvirt</code> you can let it automatically probe
| |
| the hypervisor URI if you don't know it ahead of time. This doesn't
| |
| work with remote URIs because you need to have something to put in
| |
| the URI scheme before the hostname:
| |
| * qemu+ssh://somehost/system
| |
| * xen+tcp://somehost/system
| |
| | |
| This is then translated into the URI:
| |
| * qemu:///system
| |
| * xen:///
| |
| | |
| ...
| |
| | |
| This patch adds a 'remote' URI scheme, usable like this:
| |
| * remote+ssh://somehost/
| |
| * remote+tcp://somehost/
| |
| | |
| ...
| |
| | |
| This finally makes the Avahi[3] broadcasts useful - they only include
| |
| info on the hostname + data transport (SSH, TCP, TLS), not the HV
| |
| type. So letting us use auto-probing remotely is the missing link."

| ==== Thread Safety for libvirtd Daemon and Drivers ====
| |
| [[DanielBerrange|Daniel P. Berrange]] posted[1] a huge series of 28 patches
| |
| which add "thread safety for the
| |
| <code>libvirtd</code>
| |
| daemon and drivers, and makes the daemon multi-threaded in processing
| |
| RPC calls. This enables multiple clients to be processed in parallel,
| |
| without blocking each other. It does not change the thread rules for the
| |
| virConnectPtr object though, so each individual client is still serialized."
| |
| ...
| |
| "This touches a huge amount of code, so I'd like to get this all merged
| |
| ASAP as it'll be really hard to keep it synced with ongoing changes."

| ==== libvirt 0.5.0 and KVM migration ==== | | ==== RHEL and Fedora Virtualization Feature Parity ==== |
| Mickaël Canévet
| | Robert Day wondered how the virtualization features<ref>http://www.redhat.com/virtualization/rhev/</ref> of Red Hat Enterprise Linux 5.4 |
| Mickaël Canévet
| | compared to Fedora 12. |
| [1]
| |
| "I just installed libvirt 0.5.0 on Debian Lenny with KVM 0.72 to try KVM
| |
| > migration support.
| |
| "

| Chris Lalancette
| | explained<ref>http://www.redhat.com/archives/fedora-virt/2009-December/msg00040.html</ref> |
| [2] | | "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." |
|
| |
|
| "Yes, it is supposed to work, but yes, you need a very, very new KVM. In
| | <references /> |
| particular, you need at least kvm-77, and it won't really work right until you
| |
| get to kvm-79."
