The name of the device can only be changed when the interface is down.
This RFC patch series provides facility to dedicate CPUs to KVM guests
and enable the guests to handle interrupts from passed-through PCI devices
directly (without VM exit and relay by the host).
With this feature, we can improve throughput and response time of the device

Add an interface to set/get slave CPU dedicated to the vCPUs.
By calling ioctl with KVM_GET_SLAVE_CPU, users can get the slave CPU id
for the vCPU. -1 is returned if a slave CPU is not set.
By calling ioctl with KVM_SET_SLAVE_CPU, users can dedicate the specified
slave CPU to the vCPU. The CPU

This behavior will be replaced by later patch, which introduces direct

Add a facility to use IRQ vector different from online CPUs on slave CPUs.
When alternative vector for IRQ is registered by remap_slave_vector_irq()
and the IRQ affinity is set only to slave CPUs, the device is configured
to use the alternative vector.

Make interrupts on slave CPUs handled by guests without VM EXIT.
This reduces CPU usage by the host to transfer interrupts of assigned
PCI devices from the host to guests. It also reduces cost of VM EXIT
and quickens response of guests to the interrupts.
When a slave CPU is dedicated to a vCPU,
Enable APIC to handle interrupts on slave CPUs, and enables interrupt
routing to slave CPUs by setting IRQ affinity.
As slave CPUs which run a KVM guest handle external interrupts directly in

That requires interrupts to be
Avoid exiting from a guest on slave CPU even if HLT instruction is

not required, and avoiding VM exit will improve the guest's performance.
