[PATCH v4 09/12] qtest/migration-test: Skip tests if KVM not builtin on s390x/ppc64
Posted by Philippe Mathieu-Daudé 4 years, 7 months ago 
We might have a s390x/ppc64 QEMU binary built without the KVM
accelerator (configured with --disable-kvm).
Checking for /dev/kvm accessibility isn't enough, also check for the
accelerator in the binary.
