of a TPM 2.0 to activate. Valid names are for example sha1, sha256, sha384,
and sha512. If this node is provided, the set of PCR banks are activated
before every start of a VM and this step is logged in the swtpm's log.
+ If this node is removed or omitted then libvirt will not modify the

This attribute requires that swtpm_setup v0.7 or later is installed
and may not have any effect otherwise. The selection of PCR banks only works
with the ``emulator`` backend. since:`Since 7.10.0`
