The Number of vCPUs Assigned To A Guest Causes VIFs To Go Offline

Increasing the number of vCPUs assigned to a VM will reduce the number of available. For instance 10 vCPUs will have 7 active VIFs but 12 vCPUs will only allow 6 active VIFs...

Neutron: security groups fail to block traffic properly due to packstack configuration

It was discovered that the nova.conf configuration generated by PackStack did not correctly set the libvirtvifdriver configuration option if the Open vSwitch OVS monolithic plug-in was not used. This could result in deployments defaulting to having the firewall disabled unless the nova...
