Greetings,

As we started to bootstrap f28 standalone jobs we noticed basic tempest tests were failing because the libvirt on f28 did not support the default "x86_64=pc-i440fx-rhel7.6.0" [5]

Kashyap recommend switch to q35 [1].  
So we can change to q35 maybe globally in puppet [2] if Juan, Alex and Emilien approve.

Alternatively we can isolate the deployment in question w/ [3],[4]
I should restart this thread in openstack-dev[tripleo] for greater transparency. 

Thanks

Any comments on how to proceed?  We need to enable f28 jobs in the next few days, so [2] may need to be the short term answer until we get feedback.
