Then, if i don't run the unattended_install case in a test, this entry will be
the old one? that is to say, when i add the boot, ping, shutdown to the test,
after running the boot case, the entry is the same one as ping case?
I wonder when will the unattended_install case be called? I only know when
the guest os be installed.

but when i add test case such as boot, ping, shutdown to tests.cfg to run these
cases, the vm will be restarted each case, and if you delete some variants(such
as uuid ) or add some variants(such as NETMASK, GATEWAY), these variants will
automatically added or deleted correspondingly in next restart.
That is, my guest still don't get ip from dhcp after i modify the nic_mode
value(61 line) to tap. And Whether I modify the variant value of ${switch} on
or off in qemu-ifup or not, the result remain unchanged. I fell the variant
value of ${switch} in qemu-ifup should be off because my br0 stp status is no.
