Issue
Imunify360 can't install on an OpenVZ-powered server with the error:
Your OS virtualization technology openvz has limited support for ipset in containers.
Also:
# ipset list
ipset v7.1: Cannot open session to kernel.
Environment
- CentOS
- Imunify360
- OpenVZ
- kernel that's older than 3.10.0-327.10.1.vz7.12.8
Solution
- Update the kernel to version 3.10.0-327.10.1.vz7.12.8 or newer, or migrate accordingly.
- If you are sure the above requirements are met on your server, then please try to perform the following updates:
yum install ipset-libs
yum install ipset*
Afterwards, please run the Imunify installation once again.
Cause
In the OpenVZ environment, Imunify360 is incompatible with kernels that are older than 3.10.0-327.10.1.vz7.12.8.
