My current VPS is from post2host VPS-9 kvm

1) what are the Linux flavours you use ? centos, ubuntu. please mention version

i am currently using a old distro Ubuntu 14.04 LTS x64 bits.

2) could you afford to spare / reserve say 3-5 GB space on your HDD for system recovery or reinstall on your own any time you like ?

i really wish to do this but i am not a developer or IT expert. i am just a learner.

3) do you want option to emergency reboot to a live environment with vnc access and recover / reinstall from there ?

This is also new for me.

4) do you use passwords or key file to login to your vps through ssh ?

No

5) what is your current hdd partition scheme ? what would you do differently if you could configure it during install ?

Default by service provider and ubuntu done. i never make any change.
