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

I apologize for the extremely late reply to this, as I don't read the 
fedora-xen list archives as often as I should.   This one snuck past.   
In general, cobbler discussion happens on et-mgmt-tools(a)redhat.com -- 
all emails to that list (or submissions to cobbler's bugzilla component) 
will definitely catch my attention.  

This will be fixed in 0.3.5 -- which I'll push this out this week.  

Thanks,
