[one-users] Problem creating disk images

Mon May 6 10:51:57 PDT 2013

Hello Ruben,

Thanks for this.  I actually remember performing this step several months
ago when I installed 3.8, however, I did not perform this step when I
installed 4.0.

However, it seems that something is still not quite right.  I am now unable
to deploy any VM with a failure message:

>> error: internal error cannot load AppArmor profile
'libvirt-76e12b0b-7d3c-c71a-46f0-bfe44917aedb'

And a relevant entry in /var/log/libvirt/libvirtd.log (followed by a
cascading series of errors)

>> 2013-05-06 17:06:39.665+0000: 1577: error : virCommandWait:2314 :
internal error Child process (/usr/lib/libvirt/virt-aa-helper -p 0 -c -u
libvirt-76e12b0b-7d3c-c71a-46f0-bfe44917aedb) status unexpected: exit
status 1
>> 2013-05-06 17:06:39.665+0000: 1577: error : AppArmorGenSecurityLabel:446
: internal error cannot load AppArmor profile
'libvirt-76e12b0b-7d3c-c71a-46f0-bfe44917aedb'

The docs say I need to add the following line to
/etc/apparmor.d/libvirt-qemu , I think this mean I need to add the
following line to /etc/apparmor.d/abstractions/libvirt-qemu since this is
the file that is loaded by the libvirt/TEMPLATE

>> owner /var/lib/one/** rw,

After adding this entry to /etc/apparmor.d/abstractions/libvirt-qemu and
restarting apparmor my vm fails to start with the same error message.

So I found an old mailing list article about the same issue:

>>
http://lists.opennebula.org/pipermail/users-opennebula.org/2012-June/019427.html

This thread also indicates that the following line is required in
/etc/apparmor.d/usr.sbin.libvirtd

>> /var/lib/one/** lrwk,

After doing this, I am still getting the error.

The last reply in this thread says the final solution was killing the
apparmor process and restarting the apparmor service.

I performed a teardown, which didn't help so I performed a full system
reboot.

After the reboot, I still receive the error "internal error cannot load
AppArmor profile"

It appears that this issue only occurs when I am attempting to use volitile
disks.

However, when I attempt to attach a blank, persistent datablock to a
virtual machine, I get the error:

>> error: internal error process exited while connecting to monitor: kvm:
-drive
file=/var/lib/one//datastores/0/95/disk.0,if=none,id=drive-ide0-1-0,format=qcow2,cache=none:
could not open disk image /var/lib/one//datastores/0/95/disk.0: Invalid
argument

I'm not sure if this is related to disabling dynamic ownership and setting
the ownership and group to oneadmin / cloud or if it is an entierly
different error altogether.

I will say that I am still able to clone an imported disk image from the
marketplace, and it appears to launch and run successfully.

Thanks for all your help.
