Incorrect disk size and partitioning inside of Windows KVM VPS:
As a workaround in VPS itself:
- Open Command line.
Then as on screenshot:
Volume 2 - volume with incorrect size
Usually this happens with a custom template, so as an alternative workaround create another:
- Create a source VPS with the ISO image
- Run chkdsk /f in this source VPS.
- Reboot the VPS twice.
- Create a template from it.
- Create a VPS to see if the issue is reproduced
