Sorry. Original message below. =3D=3D Hi Peter et al., I came across this when running the acceptance tests in an aarch64 host. The arch-independent tests fail because, in general, they don't set a machine type. In order to avoid treating arm targets as special cases on avocado_qemu framework I prefered to attempt to promote virt as default for ARM emulation. Moreover since it represents a generic hardware and its used is broaden advised [1], I found it the right choice. Maybe that topic was discussed already but I didn't find any reference on either the mailing list and git logs. It is also true that I am an ignorant on ARM platform, thus I might be missing something. Those explain why I send this patch as RFC. [1] https://wiki.qemu.org/Documentation/Platforms/ARM Thanks, Wainer -- >8 -- Currently none arm target has a default machine type, unlike others as x86_64 and ppc64. The 'virt' (alias) type represents a generic ARM hardware, so let's specify it the default machine for ARM emulation.
