It takes a shitload of time to compile xolominer on small machines, so I've taken a compiled binary and uploaded it to github. You can get it by cloning https://github.com/svarogg/xolo_compiled.git and than extracting xolominer.tar.gz.

It have been tested on DigitalDream and https://cloud.atlantic.net/ micro instances and works perfectly.

Also, here's a script to download and install all dependancies easily:

sudo apt-get update && sudo apt-get install python-software-properties -y &&

sudo add-apt-repository ppa:bitcoin/bitcoin -y && sudo apt-get update &&

sudo apt-get install libdb4.8-dev libdb4.8 -dev libssl-dev libgmp-dev libboost-chrono1.48-dev libboost-filesystem1.48-dev libboost-system1.48-dev libboost-program-options1.48-dev libboost-thread1.48-dev build-essential software-properties-common python-software-properties git -y &&

git clone https://github.com/svarogg/xolo_compiled.git && cd xolo_compiled && tar xzvf xolominer.tar.gz && cd ~/xolo_compiled/xolominer/src

After running this just run ./primeminer -pooluser=[your wallet] -poolip=[pool ip] -poolport=[pool port] -genproclimit=[number of cores].

Also, I suggest you use tmux to keep the server running while you are not connected to ssh.
