[PATCH 0/4] Introduce shared daemon startup code
by Rafael Fonseca 28 Mar '20

28 Mar '20

Libvirt ships several daemons (libvirtd, virtlogd, virtlockd) that all have similar code around general daemon startup. Right now the code is duplicated for each daemon, but it could be shared, like in a new file src/util/virdaemon.c.

[libvirt PATCH] scripts: avoid error in DCO check on empty branches
by Daniel P. Berrangé 28 Mar '20

If the DCO check is run on an empty branch (ie one which has no commits different from master), it throws an error due to trying to interpret the empty string as a git commit SHA.

[PATCH 1/1] qemu_domain.c: remove unneeded size check in NVDIMM alignment
by Daniel Henrique Barboza 27 Mar '20

27 Mar '20

Commit 5540acb9a2b added a minimum size verification for the target size of ppc64 NVDIMMs but forgot to remove a MAX() size check that was being used in earlier reviews of that commit. The size verification makes this check unneeded since we're making sure that guestArea will always be at least equal to ppc64AlignSize.

[libvirt] [PATCH 0/3] qemu: support -overcommit cpu-pm=on|off
by Menno Lageman 27 Mar '20

27 Mar '20

QEMU introduced a CPU power management feature with commit 6f131f13e68d ("kvm: support -overcommit cpu-pm=on|off"). With this flag, kvm allows guest to control host CPU power state. This increases latency for other processes using same host CPU in an unpredictable way, but if decreases idle entry/exit times for the running VCPU, so to use it QEMU needs a hint about whether host CPU is overcommitted, hence the flag name. This patch series adds a new kvm feature 'cpu-pm' for controlling "-overcommit cpu-pm=[on|off]" <features> <kvm> <cpu-pm state='on'/> </kvm> </features> Menno Lageman (2): qemu: introduce qemuBuildOvercommitCommandLine() tests: add tests for cpu-pm feature Wim ten Have (1): qemu: add hypervisor feature cpu-pm support for kvm docs/formatdomain.html.in | 7 ++++ docs/schemas/domaincommon.rng | 5 +++ src/conf/domain_conf.c | 4 ++ src/conf/domain_conf.h | 1 + src/libvirt_private.syms | 1 + src/qemu/qemu_command.c | 39 +++++++++++++++++-- src/qemu/qemu_domain.c | 25 ++++++++---- tests/qemuxml2argvdata/kvm-features-off.args | 2 +- tests/qemuxml2argvdata/kvm-features-off.xml | 1 + tests/qemuxml2argvdata/kvm-features.args | 2 +- tests/qemuxml2argvdata/kvm-features.xml | 1 + tests/qemuxml2argvtest.c | 4 +- tests/qemuxml2xmloutdata/kvm-features-off.xml | 1 + tests/qemuxml2xmloutdata/kvm-features.xml | 1 + 14 files changed, 79 insertions(+), 15 deletions(-) -- 2.21.0
