My FC6's kernel is the most update version, 2.6.19-1.2911, but whenever I boot with Xen, I can not use X . I remember when I first installed Xen, I can start X with Domain-0. I have monitored the VMs with virt-manager, installed the VMs with virt-install. At that time, the kernel version was 2.6.18-1.2798, but after some updates, it doesn't work. My /var/log/Xorg.0.log says -------------------------------------------------------------------- Fatal server error: Caught signal 11. Server aborting -------------------------------------------------------------------- Has anybody met with such problem? Have you got a solution? Please tell me. Thank you very much. G.S. Huang
