Hi, I want to configure a new domainU from existing domain. Can I just copy the image file (/var/lib/xen/images/box) and also copy the configuration file of existing domain? The format of configuration file is like this: # Automatically generated xen config file name = "xen2" memory = "1000" disk = [ 'tap:aio:/var/lib/xen/images/box2,xvda,w', ] vif = [ 'mac=xx:xx:xx:xx:xx:xx, bridge=xenbr1', ] vnc=1 vncunused=1 uuid = "9297c728-efe7-025f-3b35-02f92474aa6e" bootloader="/usr/bin/pygrub" vcpus=1 on_reboot = 'restart' on_crash = 'restart' I will change the name to a new name, set vcpu to 4. But I don't know how to get a unique mac address and uuid. Anybody know? And except for create the image file and configuration file, what else do i need to do? PS: I use the Fedora XEN.
