Oops, I missed Chris's comment #28. Thanks.
>From comment #23, the 1.4 machine type seems to be "fast", while 1.3 is
slow. This doesn't make much sense, given the differences between the
two machine types:
enable_compat_apic_id_mode();
.driver = "usb-tablet",\
.property = "usb_version",\
.value = stringify(1),\
.driver = "virtio-net-pci",\
.property = "ctrl_mac_addr",\
.value = "off", \
.driver = "virtio-net-pci", \
.property = "mq", \
.value = "off", \
.driver = "e1000",\
.property = "autonegotiation",\
.value = "off",\
This is why I suspected the issue was not 100% reproducible.
