but then I haven't managed to build a filesystem that could be migrated and allows high performance... so it isn't much of a loss :)

[nfs works, but performance bites when compared to a fully cached local block device... anyone wanna start a new thread?]

I just use a SAN with fibre channel.. works great. I'm using CLVM, so all the xen0 boxes see the block devices with the same names; also using GFS to share home directories and such within the domU's.

Beats the crap out of the NFS solution I used to use.. :)
