[libvirt] [PATCH 0/4] RFC: vcpupin: some improvements of virsh vcpupin command
by Taku Izumi
Hi all,
This patchset improves virsh vcpupin command like the following:
(i) introduce special markup "-" and "^" which are similar to XML schema
of "cpuset" attribute
# virsh vcpupin VM 0 0-8,^4 --config
# virsh dumpxml VM
...
<vcpu>4</vcpu>
<cputune>
<vcpupin vcpu='0' cpuset='0-3,5-8'/>
</cputune>
...
(ii) allow to receive the special keyword 'r' as a cpulist parameter
when resetting vcpupin setting.
# virsh vcpupin VM 0 r --config
(iii) when resetting, that is, pinning the specified virtual cpu to
all host physical cpus, vcpupin setting will be deleted
# virsh dumpxml VM
...
<vcpu>4</vcpu>
<cputune>
</cputune>
...
The following my patchset is the prerequisite of this:
http://www.redhat.com/archives/libvir-list/2011-June/msg00390.html
*[PATCH 1/4] vcpupin: improve vcpupin definition of virsh vcpupin
*[PATCH 2/4] vcpupin: add reset option to virsh vcpupin command
*[PATCH 3/4] vcpupin: add virDomainVcpupinDel function
*[PATCH 4/4] vcpupin: add vcpupin resetting feature to qemu driver
Best regards,

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

[libvirt] Driver development
by Carlos N. A. Corrêa
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,

[libvirt] [RFC PATCH] Set and reset MAC for PASSTHROUGH mode
by D. Herrendoerfer
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'.
Best regards
Dirk

[libvirt] [libvirt-php] Work on ./example
by David Streibl
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
