Hello Xu, this issue was suppose to be fixed by https://github.com/autotest/tp-qemu/pull/1070 please let me know whether it still does not work for you. More info in-line...

The difference is that `virt` can be constructed both as mmio or pci. This is why Avocado needs a hint which representation do you have in mind. In Avocado-vt you can still specify qemu machine type by separating it with `:`, therefor if you want to use pci-based virt-rhel7.4.0 you can set the machine type to `arm64-pci:virt-rhel7.4.0`, or on upstream you can use `arm-mmio:vexpress-a15` and such. >> >> Using arm64-pci & arm64-mmio in Avocado-vt is fine.

There is already blacklist of some machines (eg. none) so eventually we can expand it if necessary. Lukáš > Thanks, > Xu > >> >> Thanks, >> -Wei >> >
