What are my options to mirror a running system (without taking it down) to have an as close as possible copy for use as a XEN guest?
Now I'm planning to install the same version of OS as domU and simply rsync everything down to it from the live system. Not sure about /boot | kernel stuff though, any problems syncing these?
Also, can I set a remote "nice" level for rsync, cap bandwidth - to avoid putting stress on the live server?
