[libvirt] [PATCH v2 0/5] Prevent losing IPv6 routes due to forwarding
by Cédric Bosdonnat
Hi Laine, all,
Here is the v2 of my series. The changes are:
* Add a commit to create a virNetDevGetName() function
* Fix Laine's comments
Cédric Bosdonnat (5):
util: extract the request sending code from virNetlinkCommand()
util: add virNetlinkDumpCommand()
bridge_driver.c: more uses of SYSCTL_PATH
util: add virNetDevGetName() function
network: check accept_ra before enabling ipv6 forwarding

[libvirt] [PATCH v2 0/3] libxl: nestedhvm support
by Wim Ten Have
From: Wim ten Have <wim.ten.have(a)oracle.com>
This patch enhances host-passthrough capability to advertise the
required vendor CPU virtualization feature which will be used to
enable 'nestedhvm' in the libxl driver.
Wim ten Have (3):
libxl: set nestedhvm for mode host-passthrough
xenconfig: add conversions for xen-xl
xlconfigtest: add tests for 'nestedhvm' support

[libvirt] [RFC PATCH 00/11] Add mdev reporting capability to the nodedev driver
by Erik Skultety
This series enables the node device driver to report information about the
existing mediated devices on the host. There is no device creation involved
yet. The information reported by the node device driver is split into two
parts, one that is reported within the physical parent's capabilities
(the generic stuff that comes from the mdev types' sysfs attributes, note the
'description' attribute which is verbatim - raw,unstructured string) and the
other that is reported within the mdev child device and merely contains the
mdev type id, which the device was instantiated from, and the iommu group
number.
Basically, the format of the XML I went for is as follows:
PCI parent:
<device>
<name>pci_0000_06_00_0</name>
<path>/sys/devices/.../0000:06:00.0</path>
<parent>pci_0000_05_08_0</parent>
...
<capability type='pci'>
...
<capability type='mdev'>
<type id='nvidia-11'>
<name>GRID M60-0B</name>
<description>num_heads=2, frl_config=45, framebuffer=512M, max_resolution=2560x1600, max_instance=16</description>
<device_api>vfio-pci</device_api>
<available_instances>16</available_instances>
</type>
...
</capability>
<iommuGroup number='20'>
<address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/>
</iommuGroup>
...
</capability>
</device>
mdev child:
<device>
<name>mdev_ef1212ff_ff23_4534_ffcd_01ff12017801</name>
<path>/sys/devices/.../ef1212ff-ff23-4534-ffcd-01ff12017801</path>
<parent>pci_0000_06_00_0</parent>
<driver>
<name>vfio_mdev</name>
</driver>
<capability type='mdev'>
<type id='nvidia-18'/>
<iommuGroup number='63'/>
</capability>
</device>
Also, since we didn't have any node device driver documentation, I created a
stub (comments are very welcome, you can shred it to pieces ;)) focusing on the
PCI devices and then adding the mdev part into that. As I said, it's still a
stub that needs lots of work on it, namely adding USBs and SCSI devices, but I
figured that the fact some parts are missing should not be a show stopper for
the nodedev-mdev patches.
Thanks,
Erik
