VMTools Nice/Device Filtering

A number of CNI implementations (such Calico, Antrea, and etc) introduce networking artifacts that interfere with the normal operation of vSphere's internal reporting for network/device interfaces. To address this issue, an exclude-nics filter for VMTools needs to be applied in order to prevent these artifacts from getting reported to vSphere and causing problems with network/device associations to vNICs on virtual machines.

The recommended exclude-nics filter is as follows for /etc/vmware-tools/tools.conf:

[guestinfo]
primary-nics=eth0
exclude-nics=antrea-*,cali*,ovs-system,br*,flannel*,veth*,docker*,virbr*,vxlan_sys_*,genev_sys_*,gre_sys_*,stt_sys_*,????????-??????

Each filter represents known CNI network/device interfaces. Most filters are straight foward, such as docker* for devices based on docker. Some filters, such as ????????-??????, aren't so straight-forward as that filter identifies Antrea devices which get created per POD.

Restart VMTools for the changes to take effect.

/etc/vmware-tools/services.sh start
/etc/vmware-tools/services.sh stop
/etc/vmware-tools/services.sh restart
