[libvirt] Cpu Modeling
by Jason J. Herne
Hi Jiri & Eduardo,
You might remember a discussion with David Hildenbrand of IBM on the Qemu
mailing list regarding a new Qemu<->Libvirt interface for cpu modeling. I am
picking up this work from David and I wanted to confirm that we are
still on the
same page as to the direction of that interface.
For your reference:
https://www.redhat.com/archives/libvir-list/2016-June/thread.html#01413
https://lists.gnu.org/archive/html/qemu-devel/2016-09/threads.html#00489
The first link is to the discussion you were directly involved in. The
second
link is to the final patch set posted to qemu-devel. The cover letter
gives a
good overview of the interface added to Qemu and the proposed use-case for
Libvirt to use this new cpu modeling support. I'll paste in the most
relevant
section for your convenience:
--------------------------------Libvirt usecase----------------------------
Testing for runability:
- Simply try to start QEMU with KVM, compat machine, CPU model
- Could be done using query-cpu-model-comparison in the future.
Identifying host model, e.g. "virsh capabilities"
- query-cpu-model-expansion on "host" with "-M none --enable-kvm"
<cpu mode='host-model'>:
- simply copy the identified host model
<cpu mode='host-passthrough'>:
- "-cpu host"
"virsh cpu-baseline":
- query-cpu-model-baseline on two models with "-M none"
"virsh cpu-compare":
- query-cpu-model-comparison on two models with "-M none"
There might be some cenarios where libvirt wants to convert another CPU
model to a static variant, this can be done using query-cpu-model-expansion
---------------------------------------------------------------------------
Now that I've hopefully refreshed your memory :) I just want to make
sure that
you are still on-board with this plan. I realize that this new approach does
things differently than Libvirt does today for other platforms. Especially
x86_64. The big differences are as follows:
1. We will invoke qemu to gather the host cpu data used for virsh
capabilities.
Today this data seems to be collected directly from the host hardware
for most
(all?) architectures.
2. virsh cpu-models {arch} will also use a Qemu invocation to gather cpu
model
data.
3. Most architectures seem to use a "map" (xml file containing cpu model
data
that ships with Libvirt) to satisfy #1 and #2 above. Our new method does
not use
this map as it gets all of the data directly from Qemu.
4. virsh cpu-baseline and cpu-compare will now invoke qemu directly as well.
Note: I'm not sure exactly how much all of this will apply just to s390 with
other architectures moving over to the new interface if/when they want
to. Or if
we will want to change all architectures to this new interface at the
same time.
Any guidance?
Thanks for your time and consideration.

[libvirt] [PATCH V3 0/4] qemu: report actual vcpu state in virVcpuInfo
by Viktor Mihajlovski
Currently, the virVcpuInfo returned by virDomainGetVcpus() will always
report a state of VIR_VCPU_RUNNING for each defined domain vcpu even if
the vcpu is currently in the halted state.
As the monitor interface is in fact reporting the accurate state, it is
rather easy to transport this information with the existing API.
This is done by
- adding a new state of VIR_VCPU_HALTED
- extending the monitor to pass back the halted state for the vcpus
- adding a new field to the private domain vcpu object reflecting the
halted state for the vcpu
- modifying the driver code to report the vcpu state based on the halted
indicator
- extending virsh vcpuinfo to also display the halted state
The vcpu state is however not recorded in the internal XML format, since
the state can change asynchronously (without notification).
V2 is a rebase on top of Peter Krempa's CPU hotplug modernization.
V3 tries to address the review comments by John and Peter.
I noticed Peter has posted (we had a tendency for mid-air collisions lately)
https://www.redhat.com/archives/libvir-list/2016-October/msg00498.html
I've applied the patches on top of mine and have seen no
issues so far.
Viktor Mihajlovski (4):
domain: Add new VCPU state "halted"
qemu: Add monitor support for CPU halted state
qemu: Add domain support for VCPU halted state
qemu: Ensure reported VCPU state is current in driver API

[libvirt] [PATCH] virlog: Enclose part of virLogDefineOutputs in HAVE_SYSLOG_H block
by Erik Skultety
Commit 640b58ab broke the mingw build because it referenced 'current_ident'
as well as 'openlog' symbols both of which are declared conditionally within
HAVE_SYSLOG_H directive. This patch fixes the broken build. Additional changes
like moving all variable declarations in virLogDefineOutputs into the
conditional block were necessary to avoid 'unused variable' errors from mingw.

I could've pushed it under build breaker rule but I'd rather be safe than sorry
that I missed anything else.

[libvirt] [PATCH] src: Threat pid as signed
by Michal Privoznik
This initially started as a fix of some debug printing in
virCgroupDetect. However it turned out that other places suffer
from the similar problem. While dealing with pids, esp. in cases
where we cannot use pid_t for ABI stability reasons, we often
chose an unsigned integer type. This makes no sense as pid_t is
signed.
Also, new syntax-check rule is introduced so we won't repeat this
mistake.

Technically, this is v2 of [1], but like 99% of the patch is
different, so I'm sending this as a completely new patch.
