[Xen-users] Converting vm from HVM to PV

[Lorenzo Milesi <lorenzo.milesi@xxxxxxxxxx>]

Hi.

As said before I installed a system with Debian6, Xen4, Drbd8 and so on. I've a 
small cluster of two Xen server. 
I'm managing the VM using virt-manager and libvirt. I created an Ubuntu VM 
using this tool, installing from CD. 
Now I'd like to convert this VM to ParaVirt, but I'm having some troubles 
understanding how to edit the config file placed in /var/lib/xend/domains/ 
properly. Searches made so far leaded to no solution. 

Does anyone can point me to a solution/documentation about that?
Thanks!


P.S. the VM config.sxp is this:
