try to start the VM: xen:balloon: Cannot add additional memory (-17) xen:balloon: Cannot add additional memory (-17) > Thanks!Beau Hello, Can you also post the output of xl info before creating the guests? AFAICT you are giving each guest 6000MB of RAM; are you sure you have enough RAM for Dom0 plus this two guests? From the output you provided, I can only see the trace of one guest booting [0] (one execution of xl), what happens with the other guest? Roger.
