[libvirt] [PATCH v4 0/4] vcpupin: configure inactive domain's CPU affinity setting
by Taku Izumi 09 Jun '11

09 Jun '11

Hi all, This patchset enables us to configure inactive domains' CPU affinity setting. This is the rebased version, but retains the version number. *[PATCH v4 1/4] vcpupin: introduce a new libvirt API (virDomainPinVcpuFlags) *[PATCH v4 2/4] vcpupin: implement the code to address the new API in the qemu driver *[PATCH v4 3/4] vcpupin: implement the remote protocol to address the new API *[PATCH v4 4/4] vcpupin: add the new option to "virsh vcpupin" command Best regards, Taku Izumi

[libvirt] Driver development
by Carlos N. A. Corrêa 08 Jun '11

08 Jun '11

Hi, I'm interested in developing a new network driver for libvirt (one for the definition and management of OpenVSwitch datapaths). I've read some of the code already, and by now my general directions are: - Change the function virNetworkDefParseXML in src/conf/network_conf.c to define and parse new configuration directives needed by my driver - Use src/network/bridge_driver.c as a template for my new driver, replacing code from the services provided by the driver (listed on "virNetworkDriver" type) with my own code, for my own net type. Have you any other directions in this matter? Any tips? If it works, would be this code of any use to you? Best regards, Carlos "Bill" Nilton CISSP, RHCE, ITIL Foundations http://carlosnilton.com.br/

[libvirt] [RFC PATCH] Set and reset MAC for PASSTHROUGH mode
by D. Herrendoerfer 08 Jun '11

08 Jun '11

Hi to all, there is a problem present in libvirt that when a PASSTHROUGH mode DIRECT NIC connection is made the MAC address of the NIC is not automatically set and reset to the configured VM MAC and back again. The attached patch fixes this problem by setting and resetting the MAC while remembering the previous setting while the VM is running. This also works if libvirtd is restarted while the VM is running. The storing of the previous MAC address is done in a link ( currently in /tmp, but should probably go into /var/run somewhere ). Why a link ? It only uses one inode, no need to waste a whole data block for 16 bytes or less. It's also more readable by simply looking at it with 'ls -l'.

[libvirt] [libvirt-php] Work on ./example
by David Streibl 08 Jun '11

08 Jun '11

Hello, as part of my student project I am working on simple web interface which would support multiple virtualisation platforms. This of course led me to libvirt and libvirt-php more specificly. Right now I'm using modfied code of exapme Libvirt class and the plan is: - add phpdoc - refactor it to match libvirt convetion (get_domain_someting -> dmain_get_something) - split Libvirt to subclasses for domain, connection, network, storage (not completly sure if it is good idea) - add few unit tests (dont know about time and usefulness of this) Would it be welcomed if I send to whole think or even parts of it as patches to libvirt-php/example? Thanks for any reply and sorry for my english, David

[libvirt] [PATCH 0/7] lxc: Improve container startup error reporting
by Cole Robinson 07 Jun '11

07 Jun '11

Currently most LXC container startup failures result in a reported success followed immediately by a guest shutoff. This patch series tries to improve the situation by adding a basic handshake from driver<->controller and controller<->container. If the handshake fails, the driver will return the output from the guest logfile, similar to how we do for qemu guests. A few additional error reporting improvements are also included. Cole Robinson (7): lxc: Drop container stdio as late as possible lxc: Don't report error in Wait/SendContinue lxc: Refactor controller command building lxc: Improve guest startup error reporting lxc: controller: Improve container error reporting lxc: Verify root fs exists before mounting lxc: Ensure container <init> actually exists src/lxc/lxc_container.c | 67 +++++++++++------- src/lxc/lxc_container.h | 2 + src/lxc/lxc_controller.c | 63 ++++++++++++++++- src/lxc/lxc_driver.c | 173 +++++++++++++++++++++++++++++++++++++--------- 4 files changed, 243 insertions(+), 62 deletions(-) -- 1.7.4.4
