How to create a custom OpenVZ 7 template for SolusVM?

Answer

SVM_WARN: OS of the template has to be one from supported by OpenVZ 7.

1. Connect to OpenVZ 7 node over SSH.

2. Prepare a source container - install/remove necessary packages and utilities.

3. Stop, mount and enter mount point of the container

   # vzctl stop VMID && vzctl mount VMID && cd /vz/root/VMID/

   VMID can be found in SolusVM > Virtual Servers > VMID column.

   Where to find VMID

   

4. Create the template, exit and unmount the container:

   # tar -cvzpf /vz/template/cache/OS-version-arch-customname.tar.gz . && cd && vzctl umount VMID

   SVM_WARN: The format of the template has to follow the scheme above. For example - if OS of VPS is CentOS 8 x64_86, then the template filename will be centos-8-x86_64-solusvm.tar.gz.
   Dot at the end is intended - do not miss it.

5. Create cache from the template - for example above:

   # /usr/libexec/ovz-template-converter --verbose /vz/template/cache/centos-8-x86_64-solusvm.tar.gz

6. Upload created template to Master node, add it to SolusVM and sync with needed OpenVZ 7 node.

7. Create the same cache from the template on OpenVZ 7 nodes where template was uploaded:

   # /usr/libexec/ovz-template-converter --verbose /vz/template/cache/centos-8-x86_64-solusvm.tar.gz
