Re: [libvirt] [PATCH] qemuxml2argvtest: Adapt to ethernet automatic tap creation

After 9c17d665fdc5 the tap device for ethernet network type is automatically precreated before spawning qemu. Problem is, the qemuxml2argvtest wasn't updated and thus is failing. Because of all the APIs that new code is calling, I had to mock a lot. Also, since the tap FDs are labeled separately from the rest of the devices/files I had to enable NOP security driver for the test too. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- There are only 2 problems with this patch. All of them are in virNetDevTapCreate mock implementation: 1) new tap device has constant name. Even within one domain 2) new tap FDs are constant. Even within one domain I'm unable to come with better approach though. Having a static variable that is incremented each time the mock is called would not fly as it will give different results when combined with VIR_TEST_RANGE. Therefore I assume we are good so far with these two limitations.
