One minor caveat is that using "host" has side effects in some cases, causing tests to fail because they may also require KVM to be enabled.

Good point. Certainly I will consider this when reviewing new tests. > >> The resulting QEMU evocation will be like: >> >> qemu-system-x86_64 -display none -vga none -chardev socket,id=mon,path=/var/tmp/avo_qemu_sock_pdgzbgd_/qemu-1135557-monitor.sock -mon chardev=mon,mode=control -cpu host > Only thing is: can we please just break this line (I could not ignore > a 174 character line :). > >> Signed-off-by: Wainer dos Santos Moschetta <wainersm@redhat.com> >> --- >> docs/devel/testing.rst | 17 +++++++++++++++++ >> tests/acceptance/avocado_qemu/__init__.py | 5 +++++ >> 2 files changed, 22 insertions(+) > With the line broken mentioned above (which I can take care of when > queueing this patch): I will send a v3 to address your review for patch 06, so I can take care of it. > > Reviewed-by: Cleber Rosa <crosa@redhat.com> > Tested-by: Cleber Rosa <crosa@redhat.com> Thanks for the reviews! - Wainer

This introduces a new feature to the functional tests: automatic setting of the '-cpu VALUE' option to the created vm if the test is tagged with 'cpu:VALUE'. The 'cpu' property is made available to the test object as well. For example, for a simple test as: def test(self): """ :avocado: tags=cpu:host """ self.assertEqual(self.cpu, "host") self.vm.launch() The resulting QEMU evocation will be like: qemu-system-x86_64 -display none -vga none -chardev socket,id=mon,path=/var/tmp/avo_qemu_sock_pdgzbgd_/qemu-1135557-monitor.sock -mon chardev=mon,mode=control -cpu host Signed-off-by: Wainer dos Santos Moschetta <wainersm@redhat.com> --- docs/devel/testing.rst | 17 +++++++++++++++++ tests/acceptance/avocado_qemu/__init__.py | 5 +++++ 2 files changed, 22 insertions(+)
