Re: [libvirt] Why does libvirt not unlink qemu-ga or any other socket in function qemuProcessStop()

Hello,
I have defined a vm with two UNIX domain sockets. One is for qemu-ga and the
other is for my service. These two devices will act as UNIX domain socket
server. They are automatically generated by qemu. But when the vm was dead,
these two sockets were not deleted. I find that libvirt will unlink vm's
monitor socket(/var/lib/libvirt/qemu) in function qemuProcessStop(). Why
does libvirt not unlink qemu-ga or any other socket in function qemuProcessStop()?
I guess it just never occurred to anyone to implement code to unlink these
other unix sockets. While QEMU could unlink them itself, a crashing QEMU
certainly would not, so it would be good practice for libvirt to explicitly
clean up any UNIX domain sockets after a guest shuts down.
If you want to add such clean up code, please do send a patch. If you can't
write it yourself, then at least file a bug to record this issue, so that
we can track the issue.

Daniel
