If you have an USB interface enabled in a remote management application that you use to install ESXi 8.0, you see an additional standard switch vSwitchBMC with uplink vusb0
Starting with vSphere 8.0, in both Integrated Dell Remote Access Controller (iDRAC) and HP Integrated Lights Out (ILO), when you have an USB interface enabled, vUSB or vNIC respectively, an additional standard switch vSwitchBMC
with uplink vusb0
gets created on the ESXi host. This is expected, in view of the introduction of data processing units (DPUs) on some servers but might cause the VMware Cloud Foundation Bring-Up process to fail.
Workaround: Before vSphere 8.0 installation, disable the USB interface in the remote management application that you use by following vendor documentation.
After vSphere 8.0 installation, use the ESXCLI command esxcfg-advcfg -s 0 /Net/BMCNetworkEnable
to prevent the creation of a virtual switch vSwitchBMC
and associated portgroups on the next reboot of host.
See this script as an example:
~# esxcfg-advcfg -s 0 /Net/BMCNetworkEnable
The value of BMCNetworkEnable is 0 and the service is disabled.
~# reboot
On host reboot, no virtual switch, PortGroup and VMKNIC are created in the host related to remote management application network.
