[Fedora-xen] cobbler problem virt_mem virt_file_size


As you can see below there is a bug when you don't use the default
virt_ram virt_file_size

Even when I give it to the profile add the settings are correctly saved
but when cobbler list you don't see your setting
when using koan he also doesn't see the setting

my problem is that i don't have 512MB free memory so it fails

cobbler profile add --name=fc6test --distro=fc6test --virt-file-size=3

cobbler list
