Good to know about xvd. I will switch over to that convention. Do you have
reason to believe that this could be related to my original udev issue? It
seems unrelated only because my domUs will work for several weeks, and at some
point I attempt to restart a domU but it does not seem to properly release
resources and the next domU I attempt to start (could be any of them) will
always fail with the mysterious "Error: Device 0 (vif) could not be connected.
Hotplug scripts not working" which you see everywhere in this list.
Why is my kernel in dom0? No particular reason, it's just how things played
out as I built things. I'm using gentoo for dom0 and I basically built my dom0
and domU kernels at the same time while following gentoo's guide. In retrospect
I wish I had gone with prebuilt kernels, and I think I may eventually switch
over to Debian... my preference would be Ubuntu because I use those a lot
for my domUs but I have read that Ubuntu doesn't have the greatest support
for Xen. Other distro recommendations are welcome if you have them...
