swap file for linux stopped working

["Marcin M. Jessa" <lists%yazzy.org@localhost>]

Hi.

I used to create a separate SWAP file for linux and define it in my domU 
config:
disk = [ 'file:/linux/ubuntu.img,0x301,w','file:/linux/swap.img,sda2,w' ]
Then just defined swap device as hda2 in linux's fstab.
But this does not seem to work anymore but I am actually not sure when 
it stopped working since I until now
didn't use linux domU to anything serious.
Any idea what may have broken this config and how to make this work again?


Cheers,
Marcin
