virt: guest to host DoS by triggering an infinite loop in microcode via #AC exception

It was found that the x86 ISA Instruction Set Architecture is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way sequential delivering of benign exceptions such as AC alignment check exception is handled. A privileg...
