Thanks. Based on settings I expect to see your controller's management interface set to

Network configuration looks good, can you please send the output of "ip addr" in the controller?

Note: you can disconnect the controller VM from the vSwitch while investigating the issue. This way you can avoid issues with the network traffic.

i was just retrying the install and now it gets stuck on this: is there any way i can fully delete it and retry, like does it store things in temp folders?

When you redeploy it, it wipes out the controller VM and starts from scratch, there are no "leftovers" from previous runs

What we have so far: apparently the nova.conf configured by RDO is corrupted, causing the following issues. Investigating the cause on the RDO IRC channel.

More details, in case others have the same issue: lots of CentOS packages got updated on Feb 20th, causing the regression. Working on narrowing down the issue:;O=D

Found the issue: the python2-ryu package is broken. As I was suspecting we're not the only ones complaining:

Workaround: in, before running packstack --answer-file, add: exec_with_retry 5 0 /usr/bin/rpm -Uvh --nodeps

This issue has been solved by setting in:


the following line:

openstack-config --set $ANSWER_FILE general CONFIG_PROVISION_OVS_BRIDGE n

If not set, in some circumstances RDO assign the IP of the gateway to br-ex interface, causing a conflict of IPs on the network.

The fix has been committed and released in the v-magine installer available for download.
