Yes, it has to be in that directoy to comply with the SELinux security
policy - we don't want to let XenD write all over the disk.

This is completely expected & normal behaviour. The '/var/lib/xen/image/box1'
file in the host, is exposed to the guest as a *disk*. So anaconda sees
this disk and wants to partition it - this is same thing you'd see if running
anaconda on a bare-metal machine with a brandnew harddisk which hadn't been
partitioned before. Simply say 'yes', and it'll create the neccessary bits.
