With the unpredictable behaviour of the current vmentry failure patch, I think this is caused by external interrupts from the host, and since this is hard to control I was thinking of handling vmentry failure in userspace. The way I am thinking of doing it is that once a vmentry fails because of an invalid guest state we delegate the emulation to userspace, and then we'd rely on QEMU's CPU emulation to emulate instructions until we return to VMX-friendly state.
I don't have a strong grasp of the details on how the kernel- and user-space side interact, so I don't know if that'd really be possible? If it is, is it plausible to do it this way, or is it better to leave all handling within the kernel side? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
