But as multiple people stated, this is not an intended solution. You tied yourself longterm to a hardware, you had no clue that it's not suitable for your project. I suggest you to contact your provider and rely on a gesture of goodwill.I cannot upgrade to TS3 client because my Sinusbot VPS is running on OpenVZ and I cannot simply upgrade it to 3.3 as I paid it for 1 year.
(I mean, you don't want to cancel your term. With switching e.g. to KVM you even want to upgrade in price with the same run time)
You can't buy diesel with a petrol car, and expect you're mechanic to make it running with diesel.
