Hi Dustin,


I solved my problem already.


Before switching off the PC OR rebooting PC all running Guests must be
stopped with;

# xm shutdown xen1...
# xm shutdown xen2...
etc.


If without running above step on next boot/reboot all previous running
Guest will be started automatically.  It is NOT necessary creating a
symbolic link;

# ln -s /etc/xen/xen1.example.com.cfg /etc/xen/auto
etc.

to start the Guests at boot.


I have 4 Guests created on the PC, xen1, xen2, xen3 and xen4.  xen1 and
xen2 were built with "xen-create-image".  xen3 was cloned on xen2 after
its creation.  xen4 was also cloned on xen2 but after building a mail
server on it.  All of them are working and can be ssh-connected on IP
and hostname except xen4 which can be ssh-connected on IP but NOT on
domain, complaining domain not found.  I don't know its cause.  I'll
leave it for the time being.  The problem, I suppose, is caused by
cloning a running mail server.


Are you aware is there a Xen command to update and upgrade globally,
i.e. running the Xen command on Host will automatically update/upgrade
guests of same Linux distro, similar to "vapt-get" on "Vserser". 
Thanks
