[libvirt] PATCH 2/2: Support <video> element in QEMU driver
by Daniel P. Berrange 08 Jul '09

08 Jul '09

This patch extends the QEMU driver to support the <video> element for configuring the type of video adapter exposed to the guest. It implements the XML -> ARGV and ARGV -> XML conversions, so both import & export work. Some of the existing tests are updated to use the <video> element to get test coverage. The QEMU help parsing test is changed to use symbolic constants instead of black magic hex constants. This supports both old -std-vga and new -vga style QEMU args. Daniel From: Daniel P.

[libvirt] [PATCH] provide the object name on lookup error
by Daniel Veillard 08 Jul '09

There were a number of places where the object name was not not reported, based on the use I don't think the string could be NULL in any of those. I also fixed a few POOL error which were really VOLume ones.

[libvirt] daily builds of pristine upstream sources for qemu, qemu-kvm, and libvirt
by Dustin Kirkland 08 Jul '09

08 Jul '09

Howdy, developers of qemu, qemu-kvm, and libvirt. I periodically see bug reports on these lists from users of Ubuntu packages of these projects. Since these users are often running some version of the project older than the current development branch, it's more interesting to know if the user can reproduce the bug on the latest development sources. I have constructed some automation that builds Debian/Ubuntu binaries for amd64, i386, and lpia platforms directly from your master git repositories every day at 11:00 UTC, and publishes them in a special, opt-in repository. These daily builds also drop any specific patches we may be carrying, in order to minimize the delta between the binaries built and your upstream sources. * https://launchpad.net/~ubuntu-virt/+archive/virt-daily-upstream In the event that an Ubuntu user reports a problem, and there's an interest in trying to reproduce the problem against the tip of the development branch, we can point them at this resource for testing purposes. Additionally, this tool also has the ability to expose build breakages. For example (let's not debug this in this thread), at the moment, qemu's build is broken, somewhere near: .... LINK cris-softmmu/qemu-system-cris ../libqemu_common.a(esdaudio.o): In function `qesd_run_in': /build/buildd/qemu-0.10.50.20090707062004/audio/esdaudio.c:400: undefined reference to `audio_pt_lock' .... Launchpad publishes the full build logs available for each architecture at the link above. For the above example, the specific build log is: * http://launchpadlibrarian.net/28761559/buildlog_ubuntu-karmic-amd64.qemu_0.… If anyone has suggestions as to the utility of this resource, I would appreciate constructive feedback. Cheers, -- :-Dustin

[libvirt] [PATCH] allow to set path to xen userspace tools
by Guido Günther 08 Jul '09

08 Jul '09

Hi, attached patch makes the path to the xen userspace tools configurable. Debian keeps this under /usr/lib/xen-default/ instead of /usr/lib/xen/. We don't have the amd64 libs in /usr/lib64/xen either so we can use: ./configure --with-xen-tools=/usr/lib/xen-defaults --with-xen-tools64=/usr/lib/xen-defaults instead of patching src/xen_internals.c directly. Skipping above options gives the current behaviour. I checked that "make check" still passes. O.k. to apply? Cheers, -- Guido

[libvirt] [PATCH] Power Hypervisor Support for libvirt - minimum set of features
by Eduardo Otubo 08 Jul '09

08 Jul '09

Hello all, This is the initial patch for the driver for IBM Power Hypervisors. The minimum set of features are now implemented: list, list --all and dumpxml. Here is the Changeset since last PATCH I sent: * The URI has changed to: phyp://user@[hmc|ivm]/managed_system. If the system is a HMC+VIOS based, only an HMC authentication will be required. Commands will be sent to VIOS trough HMC command line. And if the system is an IVM based, then just provide the username and password for IVM. * Since the Power Hypervisor has no information about UUID's, I built a little database (uuid_db) to store and associate LPAR ID's with UUID randomly generated by the API. * The command dumpxml is implemented, but there are some informations missing. Fetching informations like fstab, os type, uptime, IP addr and so on, will only be available in a future versions of the HMC system. * The TODO list is now set to implement life cycle functions. Thanks in advance, []'s -- Eduardo Otubo Software Engineer Linux Technology Center IBM Systems & Technology Group Mobile: +55 19 8135 0885 otubo(a)linux.vnet.ibm.com

[libvirt] PATCH: 0/3: Run QEMU guests within a CGroup
by Daniel P. Berrange 08 Jul '09

08 Jul '09

Recent Linux kernels have a new concept of 'CGroups' which is a way to group tasks on the system and apply policy to them as a whole. We already use this in the LXC container driver, to control total memory usage of things runing within a container. This patch series is a proof of concept to make use of CGroups in the QEMU driver. The idea is that we have a 3 level cgroup hierarchy - Top level; contains the libvirtd daemon itself - 2nd level: one per libvirt driver, but dos not contain any processes. - 3rd level: one per guest VM. Contains the QEMU process The host admin can do control on the top level and 2nd level to set an overall system policy. libvirt will then provide APIs / capabilities to control individual VMs policy.

[libvirt] Can't boot guest after adding an IDE storage

Hi, We installed Fedora 11 guest in an emulated SCSI disk using virt-install. After the installation the guest was shutdown and additional IDE virtual storage was added to the guest. When we try to boot the guest from virt-manager, it tries to boot from the newly added IDE storage (instead of installed SCSI storage) and fails to boot. It seems that how the disk devices are sorted is the problem. There is a bug opened to track this issue: https://bugzilla.redhat.com/show_bug.cgi?id=507271 As dicussed in the bugzilla, ideally there should be a 'bootable' flag for each storage device. Also virt-manager could another option to specify which disk to boot from. Regards, M. Mohan Kumar

[libvirt] Switch from CVS to GIT is done
by Daniel Veillard 07 Jul '09

Thanks to Jim Meyering we now have a new git repository, I deprecated the CVS repository, it's read only, you should still be able to keep it around to make patches for a few weeks if needed. The new repo is at: http://libvirt.org/git/?p=libvirt.git;a=summary Unfortunately Jim had to clean up the conversion from CVS that was used previously at git://git.et.redhat.com/libvirt.git so the two are not compatible and the best is to clone a new tree using git clone git://libvirt.org/libvirt.git and then copying over your set of patches with "git format-patch" in the old dir and "git am" to paste them into the new cloned-dir (Jim can certainly provide more details if needed). Let us know if you see something weird in the new tree or on the web site, I have updated the download informations at http://libvirt.org/downloads.html A few things may change but I guess the switch is done at this point, Many thanks to Jim for maintaining the old tree and the migration !
