Re: [Xen-users] LVM backed domu with lvm inside

[Wayne Mallett <wayne.mallett@xxxxxxxxxx>]

I have separate LVs on dom0 for each volume on the domU and then have  
extra fields in the virtual disks definition in the XEN config file.   
For example:
disk = [ 'phy:/dev/iscsi_path1/myhost_root,sda1,w', 'phy:/dev/vg0/ 
myhost_swap,sda2,w', 'phy:/dev/iscsi_path2/myhost_opt,sda3,w' ]
On the domU host - sda1 is for /, sda2 is for swap, and sda3 is for / 
opt.
Regards,

Wayne
