CentOS 7.x Centmin Mod .09 network not starting after reboot

Please fill in any relevant information that applies to you:

• CentOS Version: centos-7-x86_64.tar.gz in ProxMox container (CentOS 7.3.1611)
  
• Centmin Mod Version Installed: 123.09beta01
• Nginx Version Installed: nginx/1.13.1
• PHP Version Installed: PHP 5.6.30
• MariaDB MySQL Version Installed: not sure cant connect to mysql server
  
• When was last time updated Centmin Mod code base ? : installed and reinstalled today
  
• Persistent Config: No

I installed proxmox image provided by SoYouStart (OVH) on a E5 1620v2 16gb 2x2tb sata dedicated server.
Imported centos-7-x86_64.tar.gz (https://download.openvz.org/template/precreated/)
Created a container (LXC) with 8gb ram 80gb drive, setup mac, ip and ipv6
And installed centminmod using:

Code:

yum -y update; curl -O https://centminmod.com/betainstaller.sh && chmod 0700 betainstaller.sh && bash betainstaller.sh

.
Added a vhost and after config everything works great. Tested ssl and ipv6 both returned perfect result.
When I reboot I can no longer connect to ssh nor the websites are working.
I can connect to VPS from node using "pct enter 100". And the VPS is running.
Not sure how to pinpoint the issue.

What I already tried:
Reinstalled several times with approximately the same setup and every time the same error.
If I restart before installing centmin vps well restart correctly.
I got same error for centos 6 and 09beta01.
I tried centos 7 and upgrade from stable to betausing menu 23 and then nginx update but got an error and nginx was not copilled. something was missing not sure what was it. Well try to reproduce again.

I tried for the last 2 days but cant find why is network not starting on centos 7 with 09beta01

Not sure if important but
systemctl returns

Code:

tmp.mount                              loaded failed failed    /tmp

 

Well the KVM be slower for websites load time than ovz? Or I misunderstood that part?

 

Great. Well try with KVM. Thanks for the quick replies and all the work you put in this project, it really is awesome.
