I'm trying to troubleshoot why i'm unable to launch a Xen HVM guest. I'm encountering the following error, *map shared IO page returned error 3 *

You can not start a Xen guest by just starting the device model (qemu). You have to use "xl create", which starts qemu among other initializations.

qemu emulates *some* devices, but para-virtualized devices, memory management etc. are done by the hypervisor, which doesn't know that you started qemu...
