[Fedora-xen] cobbler problem virt_mem virt_file_size

[Mario Verbelen]

Hi,

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
(/var/lib/cobbler/profiles)
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
--virt-ram=96
