I couldn't find anything better close to me, too bad linode is in USA
but i use it for blog and some other little things and latency doesn't
matter much.

Anyway i don't think virtual memory really matters here. I didnt use
OpenVZ but i used similar Linux VServer on work server and for example
my tomcat VPS have memlimit 160MB + 240 MB swaplimit and virtual mem
used is about 530 MB (swap usage is zero)
