<div>I see your point. I did a quick research and it seems to be
a limitation on virt-aa-helper: <br>

spaces.xml | /usr/lib/libvirt/virt-aa-helper -d -p 0 -r -u

<div>I decided to dig further and I took a look at
virt-aa-helper source code and it does, indeed, check if the
name does not contain spaces (as well as one of /, [, ] and
*). Because of that, it seems that it's unable to
load/recreate (?) the profile.<br>

I find this problem on Ubuntu 12.10 and libvirt 0.9.13<br>
<br>
alinefm@alinefm:~/libvirt$ libvirtd --version<br>
libvirtd (libvirt) 0.9.13<br>
<br>
But I've just checked the latest libvirt (from source code) on same
Ubuntu node and I was able to create and start a domain (which name
contains spaces)<br>
The current upstream version is 1.2.1<br>

I don't think having a space in a VM's name is a
problem. I am able to create a VM named "hello world"
using Kimchi and virsh.<br>
<br>
We should not add a limitation like this one to Kimchi
(i.e. restricting the VM name) if there's not a real
reason to.<br>

Agree.<br>
<br>
Seems this problem is on a deeper layer.<br>
In a quick search on the internet I found a lot of forums
related to "libvirtError: internal error cannot load
AppArmor profile"<br>
We need to investigate more to find the root cause.<br>

Kimchi fails to start the guest OS if the user names
it with spaces. As pointed in the issue #306, other VM
management interfaces prevent the user from creating a
guest OS if the name contain invalid characters.<br>
<br>
This patch adds a validation logic that prevents the
user from naming a Guest OS with anything other than
alphanumeric chars, '-', '.' or '_'.<br>
