|
|
|
For the pseries-rhel7.3.0 .. pseries-rhel7.5.0 machine types we have -sxxm
|
|
variants, the only difference being that the -sxxm variants have the
|
|
Spectre and Meltdown mitigations available to guests by default.
|
|
|
|
We'd delayed on adding a similar variant for RHEL 7.6, in the hope that we
|
|
might be able to enable the mitigations by default for the ordinary 7.6
|
|
machine type. This requires that updated POWER8 firmware (FW860.51 or
|
|
newer) be installed on the host.
|
|
|
|
The updated firmware was only released late May, and it's not clear how
|
|
quickly and widely it will be deployed. For that reason, plus for
|
|
consistency in how things need to be configured across rhel-7.y, we're now
|
|
adding a pseries-rhel7.6.0-sxxm machine type.
|
|
|
|
Upstream status: downstream only
