[libvirt] [PATCH] Fix python error reporting for some storage operations
by Cole Robinson
In the python bindings, all vir* classes expect to be
passed a virConnect object when instantiated. Before
the storage stuff, these classes were only instantiated
in virConnect methods, so the generator is hardcoded to
pass 'self' as the connection instance to these classes.
Problem is there are some methods that return pool or vol
instances which aren't called from virConnect: you can
lookup a storage volume's associated pool, and can lookup
volumes from a pool. In these cases passing 'self' doesn't
give the vir* instance a connection, so when it comes time
to raise an exception crap hits the fan.
Rather than rework the generator to accomodate this edge
case, I just fixed the init functions for virStorage* to
pull the associated connection out of the passed value
if it's not a virConnect instance.
Thanks,
Cole

vhost-user-blk bypasses the QEMU block layer, so NBD storage migration
at the QEMU level will not work for the vhost-user-blk disk.

[libvirt] Supporting vhost-net and macvtap in libvirt for QEMU
by Anthony Liguori
Disclaimer: I am neither an SR-IOV nor a vhost-net expert, but I've CC'd
people that are who can throw tomatoes at me for getting bits wrong :-)
I wanted to start a discussion about supporting vhost-net in libvirt.
vhost-net has not yet been merged into qemu but I expect it will be soon
so it's a good time to start this discussion.
There are two modes worth supporting for vhost-net in libvirt. The
first mode is where vhost-net backs to a tun/tap device. This is
behaves in very much the same way that -net tap behaves in qemu today.
Basically, the difference is that the virtio backend is in the kernel
instead of in qemu so there should be some performance improvement.
Current, libvirt invokes qemu with -net tap,fd=X where X is an already
open fd to a tun/tap device. I suspect that after we merge vhost-net,
libvirt could support vhost-net in this mode by just doing -net
vhost,fd=X. I think the only real question for libvirt is whether to
provide a user visible switch to use vhost or to just always use vhost
when it's available and it makes sense. Personally, I think the later
makes sense.
The more interesting invocation of vhost-net though is one where the
vhost-net device backs directly to a physical network card. In this
mode, vhost should get considerably better performance than the current
implementation. I don't know the syntax yet, but I think it's
reasonable to assume that it will look something like -net
tap,dev=eth0. The effect will be that eth0 is dedicated to the guest.
On most modern systems, there is a small number of network devices so
this model is not all that useful except when dealing with SR-IOV
adapters. In that case, each physical device can be exposed as many
virtual devices (VFs). There are a few restrictions here though. The
biggest is that currently, you can only change the number of VFs by
reloading a kernel module so it's really a parameter that must be set at
startup time.
I think there are a few ways libvirt could support vhost-net in this
second mode. The simplest would be to introduce a new tag similar to
<source network='br0'>. In fact, if you probed the device type for the
network parameter, you could probably do something like <source
network='eth0'> and have it Just Work.
Another model would be to have libvirt see an SR-IOV adapter as a
network pool whereas it handled all of the VF management. Considering
how inflexible SR-IOV is today, I'm not sure whether this is the best model.
Has anyone put any more thought into this problem or how this should be
modeled in libvirt? Michael, could you share your current thinking for
-net syntax?

[libvirt PATCH v3 00/21] Add support for persistent mediated devices
by Jonathon Jongsma
This patch series follows the previously-merged series which added support for
transient mediated devices. This series expands mdev support to include
persistent device definitions. Again, it relies on mdevctl as the backend.
It follows the common libvirt pattern of APIs by adding the following new APIs
for node devices:
- virNodeDeviceDefineXML() - defines a persistent device
- virNodeDeviceUndefine() - undefines a persistent device
- virNodeDeviceCreate() - starts a previously-defined device
It also adds virsh commands mapping to these new APIs: nodedev-define,
nodedev-undefine, and nodedev-start.
Since we rely on mdevctl for the definition of ediated devices, we need a way
to stay up-to-date with devices that are defined by mdevctl (outside of
libvirt). The method for staying up-to-date is currently a little bit crude
due to the fact that mdevctl does not emit any events when new devices are
added or removed. As a workaround, we create a file monitor for the mdevctl
config directory and re-query mdevctl when we detect changes within that
directory. In the future, mdevctl may introduce a more elegant solution.
changes in v3:
- streamlined tests -- removed some unnecessary duplication
- split out patch to factor out node device name generation function
- split nodeDeviceParseMdevctlChildDevice() into a separate function
- added follow-up patch to remove space-padded alignment in header
- refactored the mdevctl update handling significantly:
- no longer a separate persistent thread that gets signaled by a timer
- now piggybacks onto the existing udev thread and signals the thread in t=
he
same way that the udev event does.
- Daniel suggested spawning a throw-away thread to handle mdevctl updates,
but that introduces the complexity of possibly serializing multiple
throw-away threads (e.g. if we get an 'created' event followed immediate=
ly
by a 'deleted' event, two threads may be spawned and we'd need to ensure
they are properly ordered)
- added virNodeDeviceObjListForEach() and virNodeDeviceObjListRemoveLocked()
to simplify removing devices that are removed from mdevctl.
- coding style fixes
- NOTE: per Erik's request, I experimented with changing the way that mdevctl
commands were generated and tested (e.g. introducing something like
virMdevctlGetCommand(def, MDEVCTL_COMMAND_<SUBCOMMAND>, ...)), but it was
too invasive and awkward and didn't seem worthwhile
Changes in v2:
- rebase to latest git master
Jonathon Jongsma (21):
tests: remove extra trailing semicolon
nodedev: introduce concept of 'active' node devices
nodedev: Add ability to filter by active state
nodedev: expose internal helper for naming devices
nodedev: add ability to list and parse defined mdevs
nodedev: add STOPPED/STARTED lifecycle events
nodedev: add mdevctl devices to node device list
nodedev: add helper functions to remove node devices
