In OSP11 ComputeHostnameFormat is set to '%stackname%-novacompute-%index% so we'll most probably hit the same issue with it as in the past:
[stack@undercloud-0 ~]$ grep -A3 Compute /usr/share/openstack-tripleo-heat-templates/roles_data.yaml | grep HostnameFormatDefault
HostnameFormatDefault: '%stackname%-novacompute-%index%'
[stack@undercloud-0 ~]$ rpm -qa | grep tripleo-heat-templates
openstack-tripleo-heat-templates-6.0.0-0.20161130195427.9cd0c5a.el7ost.noarch
