Unable to get appcache tarball name for

[amurleopard]

When creating a openvz contain you get this error

$ sudo vzctl create 110 --ostemplate centos-7-x86_64-minimal
Unable to get appcache tarball name for 110.conf with ostemplate centos-7-x86_64-minimal
Destroying Container private area: /vz/private/110
Warning: Container is in old data format, unregistration skipped
Container private area was destroyed
Creation of Container private area failed

This generally mean openvz does not know about the template you are trying to create a container with or the template is in the wrong format on the openvz site.

See this link of precreated templates: https://openvz.org/Download/template/precreated

For precreated templates you should not need to download anything, if the template is good then everything should work.
