[PATCH 0/2] virDomain: fix problems when setting qos on ovs managed interface
by zhangjl02 10 Aug '21

10 Aug '21

Two problems are found and fixed below: 1. Ingress rules is not clean on previous version of virNetDevOpenvswitchInterfaceClearQos. 2. If errors occurs when removing inbound qos on multi interfaces vm, some rules may not be delete as aspected. Fix by: Instead of cleaning all qos rules each time new qos is set, tx and rx's qos are set or cleaned respectively. Replace virReportError with VIR_WARN to let the cleaning process continue when error occurs. Add ifname into ovs querying statements, which will reduce failure of removing qos on the other interfaces of the same vm. Test virNetDevOpenvswitchInterfaceSetQos and virNetDevOpenvswitchInterfaceClearQos with dryrun method. Since commands in tests are not actually run, it is difficult to emulate some complex senario, such as set and then update qos. So basic tests are added in patches.

[PATCH 0/7] vmx: Support super wide SCSI bus
by Michal Privoznik 06 Aug '21

06 Aug '21

As of vSphere 6.7 there can be up to 64 units on a SCSI bus. Honestly, I'm not a big fan of 5/7 but we want to support three different values and one of them doesn't depend on the driver that's assigning the disk address, but at a runtime information. Thus using xmlopt is not good enough. Any clever idea is very welcome.

[libvirt PATCH 0/7] Fix some mutex related issues
by Tim Wiederhake 05 Aug '21

05 Aug '21

The calls to pthread_mutex_{lock,unlock,destroy} in "virthread.c" ignore the return value of these functions. This series fixes all "double unlock mutex" and "destroy locked mutex" issues I came across and adds checks to the calls to pthread_mutex_*, so no new issues of this type are introduced. Patches 1, 2, 3, and 4 fix the issues, patches 5, 6, and 7 add the checks. See https://gitlab.com/twiederh/libvirt/-/pipelines/348505233 and https://gitlab.com/twiederh/libvirt/-/pipelines/348505233 (only patches 5, 6, and 7).
