[Engine-devel] RES: oVirt 3.4 test day - PPC support

[Vitor de Lima]

Maybe this is a problem with ovirt-host-deploy, it must be configured to avoid overwriting your vdsm.conf file. There are instructions in the wiki:

Assunto: oVirt 3.4 test day - PPC support

Hi,

I tried to test various engine features related to PPC support,
However since I don't have a real Power PC HW I tried using the fake PPC configuration introduced by http://gerrit.ovirt.org/#/c/18718

So I added the following configuration to /etc/vdsm/vdsm.conf on a x86_64 host:

   fake_kvm_support=true
   fake_kvm_architecture=ppc64

And indeed it looked successful as you can see below

[root at bazulay1 ~]# vdsClient -s 0 getVdsCaps | grep -i cpu
        cpuCores = '4'
        cpuFlags = 'powernv,model_POWER7_v2.3'
        cpuModel = 'POWER 7 (fake)'
        cpuSockets = '1'
        cpuSpeed = '3401.000'
        cpuThreads = '8'


However after creating the appropriate cluster:
CPU Architecture = ppc64
CPU name = IBM POWER 7* (meaning I tried all IBM POWER 7... cpus)

Adding the host always ended in non operational status with the error:

"Host bazulay1 has architecture x86_64 and cannot join Cluster TESTDAY-CLUSTER which has architecture ppc64."


Thanks
