NCP Exam - Question 63


What is the function of the virbr0 bridge on AHV?

Show Answer
Correct Answer: AC

The virbr0 bridge on AHV is responsible for carrying management and storage communication between the Controller Virtual Machine (CVM) and the AHV host. This bridge manages internal communication within the AHV environment, ensuring that the necessary data and commands can flow between the CVM, which handles many of the storage and management functions, and the hypervisor host, ensuring efficient operation and coordination.

Bridge Bridges act as virtual switches to manage network traffic between physical and virtual network interfaces. The default AHV configuration includes an OVS bridge called br0 and a native Linux bridge called virbr0. The virbr0 Linux bridge carries management and storage communication between the CVM and AHV host. All other storage, host, and VM network traffic flows through the br0 OVS bridge. The AHV host, VMs, and physical interfaces use “ports” for connectivity to the bridge. https://www.nutanixbible.com/5a-book-of-ahv-architecture.html#:~:text=The%20virbr0%20Linux%20bridge%20carries,through%20the%20br0%20OVS%20bridge.
