This is annoying! I have a CentOS7 virtual machine running on VirtualBox. Short version: At boot the system locks with a message: "Failed to load SELinux policy, freezing." VirtualBox thinks it is still running, and I can see it consuming a small amount of CPU time. But it never goes past this message. The problem actually started with a problem in the sound system on this virtual machine. It would boot a ways through, then abort with no warning and no message. It just went away. Looking at the VirtualBox log file, I saw that the last line in the file was something about failing to initialize a stream associated with PulseAudio. In VirtualBox settings for the machine I disabled all audio. It then booted. I was in the process of gathering information for a problem report at VB when it started giving the message about SELinux policy. There were several aborts including one where it almost got to loading the X server and going graphical. SELinux is disabled on the computer, so I don't understand why it is even trying to load a policy. Is there a kernel parameter I can give it to stop SELinux? Is there any other way to get past this message? -- Bill Gee
