Serge,
Thanks again for your assistance with this. I will leave cgroup un-mounted for
now as I do not believe I lose anything by doing so.
After all this effort I suspect the lack of qemu USB2 support will be a
show stopper anyway
Best regards
Roy

Serge,
Any more thoughts on this one, it causes me some significant issues so I would
really like to get to the bottom of it if possible.

Serge,
Unfortunately I have only one vm capable host which is my main machine,
firewall, PBS, family desktop etc. It is an AMD Phenom II, the only other kit I
have is not 64bit and has no virtualisation capabilities. I am reluctant
therefore to risk this unless there in no other way forward.
Serge,
I would add that the system runs on software raid with LVM2 and it
would seem that simply taking a full backup and restoring after trying
alternative Kernel. is also non-trivial.

Done but no difference. Apparmor_status reports:
apparmor module is loaded.
apparmor file system not loaded
Still get not permitted error.
Did this with android phone in debug mode to avoid any cups related
issue.

Done as requested but no change. I no longer get my host reporting that it has
seen a new printer but the KVM guest still does not see the device. The log
file is still showing operation not permitted on a regular basis.
Any other thoughts?

I already have rapper in place to give me multi-core capability so I will edit

Done and I will attach the trace. We appear to get the following extract at

Serge,
My wrap is similar to the one you had suggested. I use virt-manager which lacks
some capability in particular i wanted to pass multiple core to guests. The
wrap makes no odds though as I have the same result when I do nots use it.

Attached to call as requested. Is there not a way to put apparmor into a
complain mode rather than enforce to rule this out once and for all?

Serge,
No good I'm afraid. I am still getting repeated
/dev/bus/usb/001/002: Operation not permitted in the VM log file.
Is it perhaps possible that something else (e.g. the linux printing
system) already has exclusive access to these devices?

I get the following, not sure if this is useful.

I believe I have now added the additional items requested. The ID
of the device and the connected point is now different, let me know if
this confuses things.
