[libvirt] Process to upstream new driver for proprietary hypervisor?
by Scott Bissett
Hello,
I am currently implementing a libvirt driver for my company's proprietary custom hypervisor. I have used the VMware driver as a design template, since it is interfacing a closed-source hypervisor as well.
Ultimately, as we approach a minimally-usable implementation, we would like to upstream our driver mods to libvirt source. What is the process to do so? This is all new to me and my organization.
For some brief background info, I am maintaining a git repo of our new code, plus ed scripts to modify libvirt source files. I am using quilt to create patches which are given to dpkg-buildpackage to create our own .deb packages. (I am working on Ubuntu at the moment; soon I will try to address repackaging rpms for CentOS).
I appreciate any tips, pointers, suggestions, etc.

[libvirt] RFC: what are the requirements to domain id
by Nikolay Shirokovskiy
Hi, all.
Domain id is somewhat required feature for hypervisors: virsh list prints
them by default and active/inactive distinction is based on this id value
analysys. But other than -1 is reserved for inactive domains there is no
further requirements for it, one can happily keep them 0 for active domains.
Looks like some drivers use process pids for this purpose. Qemu driver use
its own incrementing counter and domain ids endure libvirtd restart. Vz do not
provide a suitable value so the question arises can some simple id
implementation be good enough? By simple I mean to keep counter as long as
daemon lives and do not introduce any additional persistent state. As I said
before there is basically no option to not to support it.
A more profound question is what is this id for? How it is supposed to be used?

[libvirt] [PATCH 0/3] RFC: qemu: drop vioserialaddr cache
by Cole Robinson
qemuDomainObjPrivate caches three lists of device addresses:
virDomainPCIAddressSetPtr pciaddrs;
virDomainCCWAddressSetPtr ccwaddrs;
virDomainVirtioSerialAddrSetPtr vioserialaddrs;
Yet I can't quite tell what issue they fix... they are only used
at hotplug time for checking for address collisions, however it
appears that we can generate those lists on demand from the runtime
XML, which contains all the info we need.
In truth I only looked deeply at the vioserialaddrs list... perhaps
PCI has more to it. But at least for virtio serial it looks like
this caching can be dropped. CCing jtomko who originally added it
If this is acceptable, dropping all the caching will be a step
towards unifying all uses of qemuDomainAssignAddresses, rather
than sprinkling around a dozen call sites throughout the code.
Also (again if this is acceptable), there's more cleanup to do
here, dropping some now unused code in domain_addr
Cole Robinson (3):

[libvirt] [PATCH 0/7] More QEMU_CAPS_DEVICE cleanups
by Ján Tomko
While looking at Laine's patches I found uses of ADDRESS_TYPE_PCI
in functions that are only called on !QEMU_CAPS_DEVICE (i.e. never).
Then I cleaned up some more code until I remembered Cole already started
doing that. So I included the only patch I could apply easily.
Cole Robinson (1):
qemu: process: Drop !QEMU_CAPS_DEVICE code
Ján Tomko (6):
Remove qemuProcessInitPCIAddresses with dependencies
qemu: always add -nodefaults
Remove DISK_BUS_XEN support from qemuBuildDiskDriveCommandLine
Assume QEMU_CAPS_DEVICE in qemuBuildDiskDriveCommandLine
Introduce qemuDiskBusNeedsDeviceArg

[libvirt] [PATCH v3 1/1] perf: add support to perf event for MBM
by Qiaowei Ren
Some Intel processor families (e.g. the Intel Xeon processor E5 v3
family) introduced some RDT (Resource Director Technology) features
to monitor or control shared resource. Among these features, MBM
(Memory Bandwidth Monitoring), which is build on the CMT (Cache
Monitoring Technology) infrastructure, provides OS/VMM a way to
monitor bandwidth from one level of cache to another.
With current perf framework, this patch adds support to perf event
for MBM.
