[Linux-cluster] Cluster in virtual machines ???

[Jayson Vantuyl]

With Xen you can present the disk to both servers simultaneously.  In  
the device entry it is important to specify that the device mode is  
w!.  The ! tells Xen to allow both VMs to access it at the same time.

I do this with AoE (ATA over Ethernet).  kblade or vblade could do  
this for you as well.
