Abstract:
A method includes, migrating a guest operating system from a first hypervisor to a second hypervisor, the first hypervisor utilizing a first virtual networking device associated with a first Non-Uniform Memory Access (NUMA) node, the first virtual networking device corresponding to a physical network device. The method further includes, after the migrating, with the second hypervisor, providing to the guest operating system, a second virtual networking device associated with a second NUMA node, the second virtual networking device having a same physical address as the first virtual networking device, the second virtual networking device corresponding to the physical network device.
