In KVM environments, the hypervisor (KVM host) is embedded in the Linux kernel, and virtual machines (KVM guests) run as Linux processes. Network connections from KVM guests are made over the virtual bridge (br0) that is configured on the KVM host.
To this virtual bridge, a virtual interface (sha0) or a physical interface of GLS is connected for communication with external networks. Moreover, a virtual NIC (vnet0) is generated at the connection of the virtual bridge to the KVM guest. KVM guests communicate with external networks via these elements.
