Description Michal Skrivanek 2018-03-23 07:18:49 UTC 
qemu option "-cpu host,compat=power8" can be used to specify a power8 guest to run on a power9 hardware.

We should apply the Cluster's CPU Type setting
Comment 1 Yaniv Kaul 2018-04-11 10:21:11 UTC 
Any idea why it's still on POST? Does it need a backport to 4.2?
Comment 2 Michal Skrivanek 2018-04-11 10:54:24 UTC 
yes it does.
Comment 4 Michal Skrivanek 2018-05-09 13:49:21 UTC 
this bug is applicable to any supported POWER CPU, so you can verify also on POWER8
