[PATCH 00/17] kvm-unit-tests/arm: initial drop
This is a v3 of a series that introduces arm to kvm-unit-tests. First, it does some tidying up of the repo. Then, it adds support for virtio-testdev. Next, it adds the basic infrastructure for booting a test case (guest), and adds a single simple test, which is a self-test. Finally, it adds support for vectors and self-tests for that support. This initial drop doesn't require kvmarm. Only qemu-system-arm, recent enough to have mach-virt, and the virtio-testdev patch[1], is required.

Are you sure you have the latest mach-virt patches for qemu? v3 of kvm-unit-tests/arm sets the load address to 0x4000, which matches the latest mach-virt. I can run these tests on my x86_64 machine, without kvm enabled, as well as on an armv7 machine with kvm enabled. Are you still running on the FastModel? I never got around to setting one up to see if that works or not. thanks, drew -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
