virt: guest to host DoS by triggering an infinite loop in microcode via #DB 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 DB debug exception is handled. A privileged user...
