[libvirt] [PATCH v2] qemu: change monitor.sock from /var/lib/libvirt/qemu/domain-*** to /var/run/libvirt/qemu/domain-***
9:08 p.m.
directory /var/lib alway is Persistence directory, but in redhat system, /var/run is
memory directory.
our running domain xml is saved at /var/run/libvirt/qemu. so if we cold reset system,
the /var/run/libvirt/qemu directory is clear, but /var/lib/libvirt/qemu/domain-*** is
saved. so there
have same /var/lib/libvirt/qemu/domain-*** directory will be left over at system cold
reset.

Almost. I see a problem with this patch. Problem is that
qemuxml2argvtest needs to be updated. Which is not trivial because state
dir is a tempdir (mkdtemp()), and thus '-monitor' part of the command
line changes with each test invocation.

Yes,In qemuxml2argvtest case, mymain call qemuTestDriverInit to init qemu driver,
qemuTestDriverInit call mkdtemp() to init stateDir, so stateDir is randomly. But
'-monitor' part of the command line must be a const value. Can I use a const value
"/tmp/lib" to instead of random value at qemuxml2argvtest?

We will have to. Looks like we don't need stateDir nor configDir in the
test anyway.

I would suggest '/does-not-exist' so we see a hard fail if we accidentally
have something in the test suite that tries to create a file in that
dir. Using fixed filenames in /tmp is a big no-no in general.

Well, we already use /tmp/lib/ for the monitor path. So sticking with it
means we don't have to update all of those ~600 files. Moreover, we
don't really create the dirs/files. But sure, having /does-not-exist may
be more robust.
