btrfs is as experimental as it gets for something already merged in the 
vanilla kernel, I had major issues with it when I did some testing on my 
own computer at home -- and it was just a scratch filesystem not subject 
to heavy use, I just cloned my home on it then moved files around for a 
few days. Wouldn't use btrfs for VM storage, not even for testing and 
certainly not the version in a 2.6.32 kernel.

If you want to try something different than what Linux has to offer, 
install an OpenSolaris-based distro and use ZFS, either as a NFS share 
for containers or as iSCSI storage for virtual disks. And don't get 
tempted by deduplication, it just slows things down unless you have HUGE 
amounts of RAM.
