Hello!
I had migrated the KVM-based CentOS 7 server to OpenVZ container according this manual (openvz.org/Physical_to_container). I solved most of the problems in the migration process such a disabling unneeded services, removing linux capabilities from files and others. But some problems remain unsolved. For example, the firewalld service isn't working:
[root@redmine /]# systemctl status firewalld
firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled)
Active: active (running) since Sun 2015-03-01 10:35:28 EST; 57min ago
Main PID: 115 (firewalld)
CGroup: /system.slice/firewalld.service
└─115 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid
Mar 01 10:35:28 redmine.juscom.ru systemd[1]: Started firewalld - dynamic firewall daemon.
Mar 01 10:35:28 redmine.juscom.ru firewalld[115]: 2015-03-01 10:35:28 ERROR: ebtables not usable, disabling ethernet bridge firewall.
In addition, here is a list of all the problems that appear during the boot process:

What can I don in this situation?
