  • Virtuozzo containers for Linux 4.0


Trying to start Virtuozzo service I am getting the error like this:
# service vz start
Starting Virtuozzo: : Loading module vzmon[FAILED]

In the file /var/log/messages I see various errors:
kernel: vzmon: Unknown symbol ve_snmp_proc_init
kernel: vzmon: Unknown symbol addrconf_sysctl_free
kernel: vzmon: Unknown symbol ve_ndisc_init
kernel: vzmon: Unknown symbol addrconf_ifdown
kernel: vzmon: Unknown symbol fini_ve_route6


The Virtuozzo for Linux 4.0 kernel cannot be loaded on a server running a SUSE-based  operating system (e.g. SUSE Linux Enterprise Server 10 with Service Pack 1) if the IPv6 module is disabled.


IPv6 should be enabled in Yast in SLES10 as it is by default. Otherwise SLES10 forbids loading of some kernel modules which are required for Virtuozzo.
