> two VBD as swap disk? 

That won't work unless you transfer the contents between them on migration.

> Swap space on NFS?? 

That'd work, although it may require a kernel patch (or at least a recompile) 
to enable swapping to NFS.

Another approach (better performing than swapping to NFS) would be to swap to 
a GNBD disk on a server somewhere.  I'm not sure if Linux can natively swap 
to GNBD but you could configure the GNBD device on both dom0's (same device 
node on each) then just export that as a VBD to the guest.

Swapoff before migration (as Anthony suggested) should also work.

Cheers,
Mark
