Re: [libvirt] PATCH: Misc user mode linux startup bugs

There's a number of annoying bugs in the user mode linux driver startup code. This patch fixes lots of them. We failed to check umlMonitorCommand for error, leading to a NULL de-reference due to another bug in that function. This patch also checks if 'res' is NULL before de-referenceing it, just in case. In the code for handling inotify delete events, we duplicated alot of the umlShutdownVMDaemon code, but forgot to close the monitor. This patches makes it just call umlShutdownVMDaemon directly. In one place where we spin in a usleep loop, we forgot to increment our retries counter, making it spin forever. Finally, switch to virKillProcess

and make the latter also avoids pid==1, since I can't imagine a time where we'd ever want to kill 'init' :-)
