Hi, this is a repost of a previous question - since then I have tried rebuilding my Xen0 kernel numerous times and trying different configurations, but I haven't yet ever got a single DomU to boot so I really don't even know what is supposed to happen, let alone how to start debugging it... Can someone please speculate on how to debug this further? It's a gentoo hardened base build. I turned off the hardened compiler to build the Xen0 kernel and the Xend demon, but all I get is a Sig11 every time I try and start the new domain!! This is a brand new Dell server and it has recompiled a lot of stuff (the whole installation several times!) absolutely flawlessly so I don't suspect any hardware problems Are there any gentoo users here please who could at least note down some basic steps that they took so I can at least try and get a ttylinux domain running!! Cheers Ed W >>>>>> Prev Message >>>>>> Hi, I have booted into a Dom0 kernel on a fairly stripped down machine just running the basics needed. However, I haven't yet managed to get a DomU booting. I constantly get the following error "Error: Received invalid response from Xend, twice." on trying to start the domain Where do I actually look to try and debug this further?
