No IP address in Proxmox OpenVZ CentOS 7 container

Standard

I have spend couple of hours to find out what is wrong with my JIRA migration to find out the problem was in CentOS upgrade from 7.0 to 7.1 :( So if your container has no venet interface and thus no IP address after reboot, the problem is in broken initscripts package and you can fix it by a patch to /etc/sysconfig/network-scripts/ifup-aliases from Redhat’s Bugzilla:
