Bug Description

1) http://libvirt.org/formatdomain.html#elementsMetadata states:
"This name should consist only of alpha-numeric characters".

2) /usr/share/libvirt/schemas/domain.rng:
<element name="name">
<ref name="domainName"/>
</element>

3) Virsh accepts <name> with spaces, but then during a vm start some misguiding output is generated. It says aa_change_profile() fails. Virsh doesn't check the config with the schema as well.

The aa_change_profile() meesage is due to the function virDomainDefParseString() (from src/conf/domain_conf.c) failing to provide the name of the domain when the domain has a space in it. The name is required in order to setup the paths for the monitor, etc in the dynamic apparmor profile and virt-aa-helper exits with error when it doesn't have it.

The bug is in either virsh accepting a space in the name on define, etc, or in not handling the space properly. Either way, the documentation is correct for now: "This name should consist only of alpha-numeric characters" and therefore this bug does not have a high priority in Ubuntu. I suggest filing a bug with upstream (see http://libvirt.org/bugs.html) if you would like this resolved in Ubuntu. If you do, please reference the upstream bug here.
