[PATCH v4 26/35] tests/functional: Convert the ppc_hv avocado test into a standalone test
Posted by Thomas Huth 3 months ago
A straight forward conversion, we just also have to remove the decorator
@skipUnless(os.getenv('SPEED')) since all non-trivial functional tests
are running in SPEED=thorough mode now. Also make sure that the extracted
assets are writable, so that the test does not fail if it gets re-run
and there are stale read-only files already around.

Expanding context:

            kernel_command_line = self.KERNEL_COMMON_COMMAND_LINE
            self.vm.add_args("-kernel", self.vmlinuz)
            self.vm.add_args("-initrd", self.initramfs)
            self.vm.add_args("-smp", "4", "-m", "2g")
            self.vm.add_args("-drive", 
f"file={self.iso_path},format=raw,if=none,id=drive0")

Should we use ,media=cdrom here too?
