Hypervisor= ubuntu 12.04.2 guest = ubuntu 12.04.4 used virt-manager to create a new storage file in qcow2 format on hypervisor and then attach it to the guest.
In virt-man I can see the disk is attached. trying virsh attach-disk I get a failure saying disk already attached virsh dump xml shows the disk at vdb as it should be but on the guest, fdisk -l shows no vdb and its not in /proc I found one reference to apparmor saying add /proc rw to hypervisor's apparmor libvirt conf But I see some release notes that might be about avoiding this ( sounds insecure) so... Do I have to stop and restart the guest, change apparmor or what? -- John Fisher
