Subject: [PATCH] domcaps: Introduce TPM backendVersion
|
|
|
032100 |
|
|
|
032100 |
We accept TPM version in the domain XML. However, supported
|
|
|
032100 |
version depends on the host (swtpm_setup binary) and thus it may
|
|
|
032100 |
be tricky for users (or mgmt applications) chose a version.
|
|
|
032100 |
Introduce machinery for reporting supported version in domain
|
|
|
032100 |
capabilities.
