Hi, I reinstalled Fedora 13 on my machine, with my graphic card removed (using the integrated one on my motherboard). Still Xen would not start normally. My fedora was on /dev/sda3(sda1&2 are windows). I just used one volume without swap. Does Xen require swap as a must? Below is the serial console output: Thanks very much! Best!
