Fedora xen - Nov 2006 - Installation says to less space on disk

Hi,

I try to install XEN on FC6 on a machine having 512 mb of ram and enough
diskspace.

i created a DOMU, having 2.5GB of Diskspace (Image-File), 256 MB Ram with
64 at start and ballooned Dom0 to 200 MB Ram.

Everything goes well, until the installation starts to get its packages.
When the download should start, i get the error message, that / just has
284 MB''s of Disk available.

I then tried to change the partition-scheme not to use LVM and wanted to
create the scheme manually. This was mission impossible, as i had no / to
indicate the mountpoints.

How could i handle this? It was also strange, that i could not use the
GUI-installer.

btw. i tried to install via virt-manager.


Thanks,
Roger
