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

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? I do have
SELinux compiled in on this kernel, but it's in non-enforcing mode
nn1 xen # xm create -c ttylinux
Using config file "ttylinux".
