Thanks, Roy. I'm sorry, this shoudl have occurred to me much sooner. Just to make absolutely sure, could you add the following to the bottom of your /etc/libvirt/qemu.conf file:
cgroup_controllers = [ "cpu", "memory" ] shut down your VM, restart libvirt-bin using sudo restart libvirt-bin and see if your VM can now access the printer? Also, could you attach the result of virsh dumpxml WindowsXP ? libvirt is supposed to automatically add entries to the devices whitelist to allow access to the usb printer, so I'm hoping the xml file will offer clues as to why it didn't. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
