From the RFC[0]
"What is Live Update?
Live Update is a specialized reboot process where selected devices are
kept operational across a kernel transition. For these devices, DMA and
interrupt activity may continue uninterrupted during the kernel reboot.
...
The primary use case is in cloud environments, allowing hypervisor updates without fully disrupting running virtual machines by keeping selected devices
alive across the reboot boundary. "
