This post is missing a few pieces of information: * What version of QEMU is this? * What is the command line? * How do you know g_poll is waiting for a signal and not for a file descriptor? * What is the backtrace of the main thread? What is the backtrace of the VCPU thread? etc. Paolo -- 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
