The only real fix is not to use lxc/kvm on one hardware in parallel. As long as you use *only* kvm/lxc you'll not see this error any more. This is because most lxc-tools do not use libvirtd for operations.
At least with version 0.8.8-1ubuntu6.5 (available from the mainline repositories) some other errors are fixed — this one is not.
