As soon as I enabled PCI passthrough on my VM while using kernel 4.2.2, my VM ran extremely slowly, and increasing the amount of RAM made the problem worse. Switching to kernel 4.1.12 fixed the problem. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
