[Xen-users] Can XEN be installed onto a running system?
Can I install XEN on an installed machine? Can I use the installed partition as / in a virtual machine? bye Ronald _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

However, I assume that what you want to know is if you can convert your current running system to become a domU running under your Xen system. The answer is ''yes'', but it''s a little involved to make it happen. What you need to do is make some free space on your HDD, install a new minimal system in there, install Xen in there, and then create a domU config file that maps the previous system''s block devices into the domU. Then edit the fstab in your new domU, cross your fingers, and boot it up. I''ve done it a bunch of times over the last few weeks, as existing development servers got turned into Xen machines, but it''s not a job for your first Xen installation, really. Better to find someone who knows Xen and partitioning fairly well or (preferably) has done this operation already. - Matt _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
