[libvirt] [PATCH 0/6] Some cleanups, improvements and bug fixes of flags usage
by Pavel Hrdina 24 Mar '15

24 Mar '15

Two bugs has been filed about wrong usage of api flags and virsh commands. After investigation of the core issue I've decide to introduce same helper macros as we have in virsh code to check mutually exclusive flags. This patch series also includes the bug fixes and some other cleanups in setvcpus code.

[libvirt] [PATCH] Document behavior of compat when creating qcow2 volumes
by Ján Tomko 24 Mar '15

24 Mar '15

Commit bab2eda changed the behavior for missing compat attribute, but failed to update the documentation. Before, the option was omitted from qemu-img command line and the qemu-img default was used. Now we always specify the compat value and the default is 0.10.

[libvirt] [PATCH] qemu: change accidental VIR_WARNING back to VIR_DEBUG
by Laine Stump 24 Mar '15

24 Mar '15

While debugging the support for responding to qemu RX_FILTER_CHANGED events, I had changed the "ignoring this event" log message from VIR_DEBUG to VIR_WARN, but forgot to change it back before pushing. Since many guest OSes make enough changes to multicast lists and/or promiscuous mode settings to trigger this message, it's starting to show up as a red herring in bug reports. --- src/qemu/qemu_driver.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 6d9217b..2bac4a9 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -4340,7 +4340,7 @@ processNicRxFilterChangedEvent(virQEMUDriverPtr driver, def = dev.data.net; if (!virDomainNetGetActualTrustGuestRxFilters(def)) { - VIR_WARN("ignore NIC_RX_FILTER_CHANGED event for network " + VIR_DEBUG("ignore NIC_RX_FILTER_CHANGED event for network " "device %s in domain %s", def->info.alias, vm->def->name); /* not sending "query-rx-filter" will also suppress any -- 2.1.0

[libvirt] [PATCH] RFC: Add domain vmport attribute
by Marc-André Lureau 24 Mar '15

24 Mar '15

The QEMU machine vmport option allows to set the VMWare IO port emulation. This emulation is useful for absolute pointer input when the guest has vmware input drivers, and is enabled by default for kvm. However it is unnecessary for Spice-enabled VM, since the agent already handles absolute pointer and multi-monitors. Furthermore, it prevents Spice from switching to relative input since the regular ps/2 pointer driver is replaced by the vmware driver. It is thus advised to disable vmport when using a Spice VM. This will permit the Spice client to switch from absolute to relative pointer, as it may be required for certain games or applications. --- PS: the patch could be split in domain+docs+qemu+test docs/formatdomain.html.in | 7 +++++- docs/schemas/domaincommon.rng | 8 +++++++ src/conf/domain_conf.c | 9 ++++++++ src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 6 ++++++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 13 +++++++++++ .../qemuxml2argv-machine-vmport-opt.args | 6 ++++++ .../qemuxml2argv-machine-vmport-opt.xml | 25 ++++++++++++++++++++++ tests/qemuxml2argvtest.c | 2 ++ 10 files changed, 77 insertions(+), 1 deletion(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-machine-vmport-opt.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-machine-vmport-opt.xml diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index be35c82..51d74d1 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -124,7 +124,12 @@ and <code>machine</code> referring to the machine type.

[libvirt] GSOC 2015: Libvirt Projects
by Richa Sehgal 24 Mar '15

24 Mar '15

Dear Mentors, I am currently pursuing Master's in University of Illinois at Urbana Champaign, USA and completed by B.Tech from Indian Institute of Technology - Delhi (IIT- Delhi). I am interested in contributing to Libvirt community through GSOC 2015. I am using VirtualBox to run Ubuntu and have used VMware Player in the past. Actually I am very interested in understanding virtualization at a more practical level and do not want to limit myself to theoretical knowledge. I have played with QEMU during the OS class, but I am new to Libvirt, and thus would like to start with beginner level projects. There are two that I found: 1. Enhancing libvirt-designer 2. Abstracting device address allocation Are these projects still open, or students have already applied to them? Are there any other projects that I can start with? I am really excited about contributing to the libvirt project. Please let me know of a suitable way of starting with these. I look forward for a useful engagement with the community this summer. My irc name is: richashi. Thanks Richa
