Recently I have tested following solutions for openvz legacy server:

 * flashcache 3.1.2 (writeback mode)
 * btier 1.3.11
 * dm-cache (bundled in openvz kernel)

Not tested btier 2.x, bcache and enhanceio due to minimal kernel version
requirements.

In my tests flashcache was the fastest when measuring random IO (iops,
latency and bandwidth).
