It is likely that guest stops to receive interrupt. I met this issue in debuging in kernel PIC patch. The normal reason is that a previous irq injection fails (IDT_Vectoring valid). It seems currnet KVM handling to IDT_Vectoring doesn't cover all situation. (The in Kernel PIC patch will try to cover this)
