Re: [libvirt] Possible documentation enhancement

I just wanted to add hooks on a node and didn't succeed. The error

Hook script execution failed: Hook script /etc/libvirt/hooks/qemu qemu

/etc/libvirt/hooks/qemu: Permission denied

After reading the whole relevant src/utils code without finding any
reason for this, I found out that it was apparmor's fault.

So maybe there's a profile for the hooks missing (at least in ubuntu's
packaging). And maybe there's room in the hook-docs for a hint about that.

Ahhh, good point. Not personally being a user of AppArmour, it didn't occur to me to consider that. ;)

Do you know the exact steps you took to allow the hook scripts to work through AppArmor? (hoping for exact commands here)

If you do, then we'll add them to the hooks documentation. :)

(SELinux may also need a similar thing, which should be looked into as well)
