[v2,1/2] automation: add a QEMU aarch64 smoke test

Commit Message

Stefano Stabellini Nov. 17, 2020, 4:21 a.m. UTC

Use QEMU to start Xen (just the hypervisor) up until it stops because
there is no dom0 kernel to boot.

It is based on the existing build job unstable-arm64v8.

Also use make -j$(nproc) to build Xen.
