I haven't made any changes to this yet. A possibility would be to put
swtpm into its own tpm-emulator cgroup and extend the XML for the TPM to
also have 'period' and 'quota':
<tpm model='tpm-tis'>
<backend type='emulator'>
<period>1000</period>
<quota>500</quota>
</backend>
</tpm>
Or we add the following to cputune:
<tpm_emulator_period>1000</tpm_emulator_period>
<tpm_emulator_quota>500</tpm_emulator_quota>
The latter would be more consistent, though i would prefer the former.
