Abstract

An apparatus includes a memory of a host computing device. The memory is to store at least one hypervisor. The apparatus also includes a processing device of the host computing device and operatively coupled to the memory. The processing device is to receive a request to connect the hypervisor to a virtual network, and to determine whether the hypervisor is connectable to the virtual network utilizing at least one connectivity check service. The at least one connectivity check service indicates whether one or more connectivity requirements are satisfied. The processing device is to further connect the hypervisor to the virtual network when the one or more connectivity requirements are indicated as being satisfied, and to perform a periodic connectivity check of the connection between the hypervisor and the virtual network.
