[libvirt PATCH] vmx: Don't error out on missing filename for cdrom
by Martin Kletzander
This is perfectly valid in VMWare and the VM just boots with an empty drive. We
used to just skip the whole drive before, but since we changed how we parse
empty cdrom drives this now results in an error and the user not being able to
even dump the XML. Instead of erroring out, just keep the drive empty.

Hotplugng disk not adding backing layers to apparmor profile
by Russell Cattelan
We have been working on a feature at IBM cloud around snapshots.
One of the workflows is to add a snapshoted disk to a running virtual
instance. This involves adding a disk that has at minimum 2 qcow2 files,
one for the active overlay and one or more backing files.
The problem we are running into is that they dynamic update of the
apparmor profile appears to only add the first file in the chain to the
profile.
It based on some experiments it appears that this should be adding
all the files to the security profile but this seems to only do the
first (topmost) file. "disk->src"
https://gitlab.com/libvirt/libvirt/-/blob/a7db0b757d210071d39e6d116e6a4bc...
I does not appear to loop over the disks where as
qemuBlockStorageSourceChainAttach does
https://gitlab.com/libvirt/libvirt/-/blob/a7db0b757d210071d39e6d116e6a4bc...
The attached disk then fails since apparmor will reject the backing
files access.
This is fairly easy to demonstrate when apparmor is active.

[libvirt PATCH 00/29] Refactor scripts in tests/cputestdata
by Tim Wiederhake
This series refactors the various scripts found in tests/cputestdata and
adds support for CORE_CAPABILITY MSR, as found on e.g. SnowRidge.
Acquiring test data on a new system is a two step process. "cpu-gather.sh"
gathers information on the target machine and has as few dependencies as
possible. "cpu-parse.sh" processes this information but requires access to
a libvirt source tree and has more dependencies, e.g. "xmltodict".
This series merges three of the four involved scripts (cpu-gather.sh,
cpu-parse.sh and cpu-reformat.py) into a single python3 script. python3
already was a dependency for cpu-gather.sh and care has been taken to not
depend on modules that are not installed by default [1]. Merging the fourth
script, cpu-cpuid.py, will come in a seperate series.
Patches 1 to 14 transform cpu-gather into a python script, preserving the
format of the output (except for consistent "\n" line endings; previously
the tool would output a mix of "\n" and "\r\n").
Patches 15 to 23 merge cpu-parse into the script. In this process, the
format of the intermediary data is changed to json.
Patches 24 to 29 add support for "all in one" operation and extracting
IA32_CORE_CAPABILITY_MSR, which can be found on e.g. SnowRidge CPUs.
Old usage:
./cpu-gather.sh | ./cpu-parse.sh
New:
./cpu-gather.py [--gather] | ./cpu-gather.py --parse
Alternative on single machine:
./cpu-gather.py --gather --parse
[1] https://docs.python.org/3/py-modindex.html

[libvirt][PATCH v1 0/3] introduce 'restrictive' mode in numatune
by Luyao Zhong
Before this patch set, numatune only has three memory modes:
static, interleave and prefered. These memory policies are
ultimately set by mbind() system call.
Memory policy could be 'hard coded' into the kernel, but none of
above policies fit our requirment under this case. mbind() support
default memory policy, but it requires a NULL nodemask. So obviously
setting allowed memory nodes is cgroups' mission under this case.
So we introduce a new option for mode in numatune named 'restrictive'.
<numatune>
<memory mode="restrictive" nodeset="1-4,^3"/>
<memnode cellid="0" mode="restrictive" nodeset="1"/>
<memnode cellid="2" mode="restrictive" nodeset="2"/>
</numatune>
The config above means we only use cgroups to restrict the allowed
memory nodes and not setting any specific memory policies explicitly.
RFC discussion:
https://www.redhat.com/archives/libvir-list/2020-November/msg01256.html
Regards,
Luyao

[PATCH 0/5] Followup to virNetDevGenerateName() patches

A few issues came up during review of this series that were better
fixed in cleanups rather than requiring yet another round of
review. (A couple of things I noticed after the other patches were
already pushed).
Laine Stump (5):
util: fix tap device name auto-generation for FreeBSD
bhyve: remove redundant code that adds "template" netdev name
qemu: remove redundant code that adds "template" netdev name
util: simplify virNetDevMacVLanCreateWithVPortProfile()

[PATCH] util: Add phys_port_name support on virPCIGetNetName
by Dmytro Linkin
Current virPCIGetNetName() logic is to get net device name by checking
it's phys_port_id, if caller provide it, or by it's index (eg, by it's
position at sysfs net directory). This approach worked fine up until
linux kernel version 5.8, where NVIDIA Mellanox driver implemented
linking of VFs' representors to PCI device in switchdev mode. This mean
that device's sysfs net directory will hold multiple net devices. Ex.:
$ ls '/sys/bus/pci/devices/0000:82:00.0/net'
ens1f0 eth0 eth1
Most switch devices support phys_port_name instead of phys_port_id, so
virPCIGetNetName() will try to get PF name by it's index - 0. The
problem here is that the PF nedev entry may not be the first.
To fix that, for switch devices, we introduce a new logic to select the
PF uplink netdev according to the content of phys_port_name. Extend
virPCIGetNetName() with physPortNameRegex variable to get proper device
by it's phys_port_name scheme, for ex., "p[0-9]+$" to get PF,
"pf[0-9]+vf[0-9]+$" to get VF or "p1$" to get exact net device. So now
virPCIGetNetName() logic work in following sequence:
- filter by phys_port_id, if it's provided,
or
- filter by phys_port_name, if it's regex provided,
or
- get net device by it's index (position) in sysfs net directory.
Also, make getting content of iface sysfs files more generic.
