Does it make any difference what the value of kernel.sysrq is set to for the Xen kernel that is running in domU? If it does, is there any way to actually send the sysrq signal to the domU in the event that the virtual machine is hung and needs reboot? Or is that all not needed because we have xm destroy available to us? Steve Timm -- ------------------------------------------------------------------ Steven C.
