assuming you're using LVs as your root and swap devices, yes

it does get just a bit trickier:

1. if you're using xen-tools to create your image, then it will create 
the file systems and swap device for you (assuming you give xen-tools 
the proper information about your LVMs)
2. if you're using your LVs as backing store for a block device (e.g., 
DRBD), then you have to create your DRBD device, and then make 
filesystems and swap on the block devices (again if you use xen-tools, 
it will do the right thing for you -- note: you need to tell 
xen-create-image to use your block devices, e.g. with options like 
--image-dev=/dev/drbd1 --swap-dev=/dev/drbd2 -- these are buried in the 
documentation)
3. if you're not using xen-create-image or something similar, you'll 
need to explicitly make your filesystem and swap device

all fresh in his mind)
