[PATCH] virNetDevOpenvswitchUpdateVlan: fix vlan tag update error
by Yi Wang 10 Feb '22

10 Feb '22

From: tuqiang <tu.qiang35(a)zte.com.cn> We try to update vlan tag by running virsh update-device command, libvirtd will report ovs-vsctl arguments error. Vlan tag update funtion does't consider the xml with no vlan configured circumstances. The steps to reproduce the problem: 1 define and start domain with its vlan configured as: <interface type='bridge'> <mac address='52:54:00:9e:bb:ac'/> <source bridge='ovs-br0'/> <vlan> <tag id='10'/> </vlan> <virtualport type='openvswitch'> </virtualport> <target dev='vnet4.0'/> <model type='virtio'/> <driver name='vhost'/> </interface> 2 define and run virsh update-device command with no vlan configured as: <interface type='bridge'> <mac address='52:54:00:9e:bb:ac'/> <source bridge='ovs-br0'/> <virtualport type='openvswitch'> </virtualport> <target dev='vnet4.0'/> <model type='virtio'/> <driver name='vhost'/> </interface> #virsh update-device dom-id novlan.xml 3 virsh command returned error, and we got an error in libvirtd.log: error : virCommandWait:2584 : internal error: exit status 1: ovs-vsctl: 'set' command requires at least 3 arguments .

[PATCH] virhostcpu: fix getting CPU freq for Apple Silicon
by Menci 09 Feb '22

09 Feb '22

The current implementation of virHostCPUGetInfo for macOS (__APPLE__) reads "hw.cpufrequency" from sysctl, which is available only on x86_64 architecture. On Apple Silicon ARM Macs, it's not available: $ sysctl hw.cpufrequency # No output $ arch -x86_64 sysctl hw.cpufrequency # Run with Rosetta 2 hw.cpufrequency: 2400000000 When running libvirtd on Apple Silicon, I got the error: cannot obtain CPU freq: No such file or directory. To fix it, we can calculate it with "hw.tbfrequency" and "kern.clockrate" instead: $ sysctl hw.tbfrequency hw.tbfrequency: 24000000 $ sysctl kern.clockrate kern.clockrate: { hz = 100, tick = 10000, tickadj = 0, profhz = 100, stathz = 100 } The result value would be hw.tbfrequency * kern.clockrate.hz.

[PULL 27/28] linux-user: Remove the deprecated ppc64abi32 target
