Subject: [PATCH] qemu: Make virQEMUCapsProbeHostCPUForEmulator more generic
|

The function is renamed as virQEMUCapsProbeHostCPU and it does not get
|
|
|
99cbc7 |
the list of allowed CPU models from qemuCaps anymore. This is
|
|
|
99cbc7 |
responsibility is moved to the caller. The result is just a very thin
|
|
|
99cbc7 |
wrapper around virCPUGetHost mostly required mocking in tests.
|
|
|
99cbc7 |
|
|
|
99cbc7 |
The generic function is used in place of a direct call to virCPUGetHost
|
|
|
99cbc7 |
in virQEMUCapsInitHostCPUModel to make sure tests don't accidentally
|
|
|
99cbc7 |
probe host CPU.
