[libvirt] 答复: [PATCH v2] qemu: change monitor.sock from /var/lib/libvirt/qemu/domain-*** to /var/run/libvirt/qemu/domain-***
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?

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.
