I've rebuild via packstack 3 F22 VMs hosting Controller,Network,Compute Node Libvirt subnet for emulating external sub-net was as follows # cat public.xml <network> <name>public</name> <uuid>d0e9965b-f92c-40c1-b749-b609aed42cf2</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr2' stp='on' delay='0' /> <mac address='52:54:00:60:f8:6d'/> <ip address='172.24.4.225' netmask='255.255.255.240'> <dhcp> <range start='172.24.4.226' end='172.24.4.238' /> </dhcp> </ip> </network> Attempt to create public sub-net via dashboard failed with message, that 172.24.4.225 is incorrect gateway dor 172.24.4.224/28 Then I created this sub-net via CLI as admin. This time ( more powerful box ) qrouter-namespace kept staying in normal shape (ifconfig) , but I was unable to ping gateway 172.24.4.225 from Network Node with qg-xxxxx (172.24.4.226) and br-ex 172.24.4.232 <code> # </code>source keystonerc_admin # ip netns exec qrouter-namespace ping -c 3 172.24.4.225 hanged Same results I got for <table height="1" width="657" bgcolor="#CCCCCC" cellpadding="2" cellspacing="1"><tbody><tr bgcolor="#EEEEEE"><td>Network <code>174.24.4.192 / 26 gateway </code><code><code>174.24.4.193</code> </code></td><td> </td></tr></tbody></table> Then I rebuilt external (neutron) and corresponding libvirt sub-net in way it always been used for AIO and two node installs (network XXX.XXX.XXX.0/24 , gateway XXX.XXX.XXX.1) . # cat public.xml <network> <name>public</name> <uuid>d0e9965b-f92c-40c1-b749-b609aed42cf2</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr2' stp='on' delay='0' /> <mac address='52:54:00:60:f8:6d'/> <ip address='192.168.174.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.174.2' end='192.168.174.254' /> </dhcp> </ip> </network> In other words used 192.168.174.0/24 as external sub-net. This time I succeeded with sub-net creation via Dashboard. I became able to ping 192.168.174.1 via both qrouter or qdhcp namespaces Outbound/inbound connectivity was tested OK for Cirros 0.3.4 and F22 cloud VMs. In meantime I believe that network calculator invoked for creating sub-nets is broken. Another issue is creating ext net via CLI which allows to create unreachable gateway. > > ----- Original Message ----- > > To enable packstack on F22 there is a hack :- > > > > # dnf install -y https://rdoproject.org/repos/rdo-release.rpm > > # dnf install -y openstack-packstack > > # dnf install -y fedora-repos-rawhide > > # dnf --enablerepo=rawhide update openstack-packstack > > > > along with disabling Neutron verification section in provision_demo.pp it > > allows AIO and > > Two node "Controller&&Network and Compute" RDO Kilo packstack installs on F22 > > VMs and bare metal boxes. > > However, splitting Controller and Network Nodes, e.g. three node packstack > > install appears not to be able to work > > in meantime, regardless successful packstack completion. > > What, actually, happens ?
