Hi all I've got a working domain0 installed on Gentoo using the latest eBuilds. The systems boots fine into dom0 and I haven't noticed any instabilities so far. Unfortunately whenever I try to create an unprivileged domU, my xend crashes and I get a paused broken domain. kings2 xen # xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 489 2 r----- 9877.4 kings2 xen # xm create -c /etc/xen/xmexodus1 Using config file "/etc/xen/xmexodus1".
