It is not necessary to invalidate the lpi translation cache when the virtual machine executes the movi instruction to adjust the affinity of the interrupt. Irqbalance will adjust the interrupt affinity in a short period of time to achieve the purpose of interrupting load balancing, but this does not affect the contents of the lpi translation cache.
