Files /etc/hosts and /etc/resolv.conf had immutable flag set:
=======================================
[root@XL-VPS-0042 ~]# vzctl mount 4304
Container is mounted
[root@XL-VPS-0042 ~]# lsattr /vz/root/4304/etc/{hosts,resolv.conf}
----i-------- /vz/root/4304/etc/hosts
----i-------- /vz/root/4304/etc/resolv.conf =======================================
Flag was set manually on behalf of system root account:
=======================================
[root@XL-VPS-0042 ~]# grep chattr /vz/root/4304/root/.bash_history chattr +i /etc/hosts chattr +i /etc/resolv.conf chattr -i /etc/hosts chattr +i /etc/hosts =======================================
I have removed this flag from files and it allowed me to start container:
=======================================
[root@XL-VPS-0042 ~]# chattr -i /vz/root/4304/etc/{hosts,resolv.conf}
[root@XL-VPS-0042 ~]# vzctl start 4304
