[CentOS] Correct xen domains path

Hi all,

Two questions

1. According to 
http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU?highlight=%28xen%29 
it would be /srv/xen or even /var/lib/xen/images.

¿What is the correct absolute path to put into the xen domains files?


2. Moreover, if you want the domU(s) boot together dom0, you should put 
the domains files (images) into /etc/xen/auto.

¿A simple symlink will be enough in this case?
