[libvirt] [RFC PATCH 0/2] Add new mdev type for aggregated resources
by Zhenyu Wang
Current mdev device create interface depends on fixed mdev type, which get uuid
from user to create instance of mdev device. If user wants to use customized
number of resource for mdev device, then only can create new mdev type for that
which may not be flexible.
To allow to create user defined resources for mdev, this RFC trys
to extend mdev create interface by adding new "instances=xxx" parameter
following uuid, for target mdev type if aggregation is supported, it can
create new mdev device which contains resources combined by number of
instances, e.g
echo "<uuid>,instances=10" > create
VM manager e.g libvirt can check mdev type with "aggregation" attribute
which can support this setting. And new sysfs attribute "instances" is
created for each mdev device to show allocated number. Default number
of 1 or no "instances" file can be used for compatibility check.
This RFC trys to create new KVMGT type with minimal vGPU resources which
can be combined with "instances=x" setting to allocate for user wanted resources.

[libvirt] [PATCHv5 00/19] Introduce x86 Cache Monitoring Technology (CMT)
by Wang Huaqiang
This series of patches and the series already been merged introduce
the x86 Cache Monitoring Technology (CMT) to libvirt by interacting
with kernel resource control (resctrl) interface. CMT is one of the
Intel(R) x86 CPU feature which belongs to the Resource Director
Technology (RDT). CMT reports the occupancy of the last level cache,
which is shared by all CPU cores.
In the v1 series, an original and complete feature for CMT was introduced
The v2 and v3 patches address the feature for the host capability of CMT.
v4 is addressing the feature for monitoring VM vcpu thread set cache
occupancy and reporting it through a virsh command.
We have serval discussion about the enabling of CMT, please refer to
following links for the RFCs.
RFCv3
https://www.redhat.com/archives/libvir-list/2018-August/msg01213.html
RFCv2

1. About reason why CMT is necessary in libvirt?
The perf events of 'CMT, MBML, MBMT' have been phased out since Linux
kernel commit c39a0e2c8850f08249383f2425dbd8dbe4baad69, in libvirt
the perf based cmt,mbm will not work with the latest linux kernel. These
patches add CMT feature to libvirt through kernel resctrlfs interface.
2 Create cache monitoring group (cache monitor).
The main interface for creating monitoring group is through XML file. The
proposed configuration is like:
<cputune>
<cachetune vcpus='1'>
<cache id='0' level='3' type='code' size='7680' unit='KiB'/>
<cache id='1' level='3' type='data' size='3840' unit='KiB'/>
+ <monitor level='3' vcpus='1'/>
</cachetune>
<cachetune vcpus='4-7'>
+ <monitor level='3' vcpus='4-6'/>
</cachetune>
</cputune>
In above XML, created 2 cache resctrl allocation groups and 2 resctrl
monitoring groups.
The changes of cache monitor will be effective in next booting of VM.
2 Show CMT result through command 'domstats'
Adding the interface in qemu to report this information for resource
monitor group through command 'virsh domstats --cpu-total'.
Below is a typical output:
# virsh domstats 1 --cpu-total
Domain: 'ubuntu16.04-base'
...
cpu.cache.monitor.count=2
cpu.cache.0.name=vcpus_1
cpu.cache.0.vcpus=1
cpu.cache.0.bank.count=2
cpu.cache.0.bank.0.id=0
cpu.cache.0.bank.0.bytes=4505600
cpu.cache.0.bank.1.id=1
cpu.cache.0.bank.1.bytes=5586944
cpu.cache.1.name=vcpus_4-6
cpu.cache.1.vcpus=4,5,6
cpu.cache.1.bank.count=2
cpu.cache.1.bank.0.id=0
cpu.cache.1.bank.0.bytes=17571840
cpu.cache.1.bank.1.id=1
cpu.cache.1.bank.1.bytes=29106176
Changes in v5:
- qemu: Setting up vcpu and adding pids to resctrl monitor groups during
re-connection.
- Add the document for domain configuration related to resctrl monitor.
Changes in v4:
v4 is addressing the feature for monitoring VM vcpu
thread set cache occupancy and reporting it through a
virsh command.
- Introduced resctrl default allocation
- Introduced resctrl monitor and default monitor
Changes in v3:
- Addressed John Ferlan's review.
- Typo fixed.
- Removed VIR_ENUM_DECL(virMonitor);
Changes in v2:
- Introduced MBM capability.
- Capability layout changed
* Moved <monitor> from cahe <bank> to <cache>
* Renamed <Threshold> to <reuseThreshold>
- Document for 'reuseThreshold' changed.
- Introduced API virResctrlInfoGetMonitorPrefix
- Added more tests, covering standalone CMT, fake new
feature.
- Creating CMT resource control group will be
subsequent job.

[libvirt] [PATCH] network: honor the ipv6 network option
by Ryan Goodfellow
According the the documentation for the ipv6 network attribute
https://libvirt.org/formatnetwork.html
"When set to yes, the optional parameter ipv6 enables a network
definition with no IPv6 gateway addresses specified to have
guest-to-guest communications."
But this is not the current behavior, the ipv6 attribute is ignored and
the resulting /proc/sys/net/ipv6/conf/<virbrX>/disable_ipv6 gets set to
1 even when ipv6="yes".
This commit fixes that by checking for the ipv6 network attribute during
bridge setup.

[libvirt] [PATCH] qemu: Put format=raw onto cmd line for SCSI passthrough
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1632833
When doing a SCSI passthrough we don't put format= onto the
command line. This causes qemu to probe the format automatically
which ends up in a warning in the domain log and possible qemu
disabling writes to the first block (according to the warning
message).

[libvirt] [RFC PATCH auto partition NUMA guest domains v1 0/2] auto partition guests providing the host NUMA topology
by Wim Ten Have
From: Wim ten Have <wim.ten.have(a)oracle.com>
This patch extends the guest domain administration adding support
to automatically advertise the host NUMA node capabilities obtained
architecture under a guest by creating a vNUMA copy.
The mechanism is enabled by setting the check='numa' attribute under
the CPU 'host-passthrough' topology:
<cpu mode='host-passthrough' check='numa' .../>
When enabled the mechanism automatically renders the host capabilities
provided NUMA architecture, evenly balances the guest reserved vcpu
and memory amongst its vNUMA composed cells and have the cell allocated
vcpus pinned towards the host NUMA node physical cpusets. This in such
way that the host NUMA topology is still in effect under the partitioned
guest domain.
Below example auto partitions the host 'lscpu' listed physical NUMA detail
under a guest domain vNUMA description.

[libvirt] ANNOUNCE: virt-manager 2.0.0 released
by Cole Robinson
I'm happy to announce the release of virt-manager 2.0.0!
virt-manager is a desktop application for managing KVM, Xen, and LXC
virtualization via libvirt.
The release can be downloaded from:
http://virt-manager.org/download/
The 2.0.0 isn't hugely significant here, the app will largely look the
same to most people. Internally we had the big change of python3 support
which definitely bumps up the minimum supported host version
virt-manager can run on.
I also took the opportunity to remove some uncommonly used features from
virt-manager's UI, chief among them the host interface management UI. In
practice I don't think this will really impact anyone because it didn't
work that well to begin with. More details are in this thread:
https://www.redhat.com/archives/virt-tools-list/2018-October/msg00032.html
The big changes in this release include:
- Finish port to Python 3 (Radostin Stoyanov, Cole Robinson)
- Improved VM defaults for supported OS: q35 PCIe, usb3, CPU host-model
- Search based OS selection UI for new VMs (Daniel P. Berrangé,
Cole Robinson)
- Track OS name for lifetime of domain in <metadata> XML
- Host interface management UI has been completely removed
- Show domain IP on interface details page (Lin Ma, Cole Robinson)
- More efficient stats polling with AllDomainStats (Simon Kobyda,
Cole Robinson)
- TPM device model and backend UI (Marc-André Lureau, Stefan Berger)
- Show <channel> connection state in UI (Lin Ma)
- Show attached devices in <controller> UI (Lin Ma)
- UI option to plug/unplug VM nic link (Simon Kobyda)
- UI support for disk discard and detect_zeroes (Povilas Kanapickas,
Lin Ma)
- Improved SUSE --location URL/ISO detection (Charles Arnold)
- cli and UI support for SCSI persistent reservations (Lin Ma)
- cli: Add --network mtu.size= option (Anya Harter)
- cli: Add --disk driver.copy_on_read (Anya Harter)
- cli: Add --disk geometry support (Anya Harter)
- cli: Add --sound codec support (Anya Harter)
- cli: Add --hostdev net/char/block for LXC (Lubomir Rintel)
- cli: Add --memorybacking access_mode and source_type (Marc-André
Lureau)
- cli: Add --boot rebootTimout (Yossi Ovadia)
- cli: Add --destroy-on-exit
Thanks to everyone who has contributed to this release through testing,
bug reporting, submitting patches, and otherwise sending in feedback!
Thanks,
Cole

[libvirt] [ocaml PATCH] doc: invoke ocamldoc with -colorize-code
by Pino Toscano
This way, the OCaml snippets are colorized.
The OCaml version required is higher than the first version shipping
ocamldoc with this option, so that can be done unconditionally.
