We do use pseries-rhel7.6.0-sxxm machine type in 4.3 (not in 4.4. that would be the preferred solution, to upgrade). > If you don’t care about security you can also modify the machine type per VM (or in engine db for all VMs) to "pseries-rhel7.6.0" I’m using an AC922 machine.

In fact I can boot the VMs with pseries-rhel7.6.0 but not with pseries-rhel7.6.0-sxxm; how do you made pseries-rhel7.6.0-sxxm works on 4.3 release? # lscpu Architecture: ppc64le Byte Order: Little Endian CPU(s): 128 On-line CPU(s) list: 0-127 Thread(s) per core: 4 Core(s) per socket: 16 Socket(s): 2 NUMA node(s): 6 Model: 2.2 (pvr 004e 1202) Model name: POWER9, altivec supported CPU max MHz: 3800.0000 CPU min MHz: 2300.0000 L1d cache: 32K L1i cache: 32K L2 cache: 512K L3 cache: 10240K NUMA node0 CPU(s): 0-63 NUMA node8 CPU(s): 64-127 NUMA node252 CPU(s): NUMA node253 CPU(s): NUMA node254 CPU(s): NUMA node255 CPU(s): Thank you for helping out. > > Thanks, > michal >> >> Thanks, >> >> _______________________________________________ >> Users mailing list -- users(a)ovirt.org <mailto:users@ovirt.org> >> To unsubscribe send an email to users-leave(a)ovirt.org <mailto:users-leave@ovirt.org> >> Privacy Statement: https://www.ovirt.org/privacy-policy.html <https://www.ovirt.org/privacy-policy.html> >> oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ <https://www.ovirt.org/community/about/community-guidelines/> >> List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/PVVQDBO2XJY... <https://lists.ovirt.org/archives/list/users@ovirt.org/message/PVVQDBO2XJY...
