When i create a VPS, i got error

[root@server70 ~]# vzctl create 102 --ostemplate ubuntu-14.04-x86_64

This is because OpenVZ recently started using ploop image for OpenVZ virtual machines. To fix this, edit /etc/vz/vz.conf

vi /etc/vz/vz.conf

Find

#VE_LAYOUT=ploop

Replace With

VE_LAYOUT=simfs

Now you will be able to create VPS.

[root@server70 ~]# vzctl create 102 --ostemplate ubuntu-14.04-x86_64
