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".
Error: Received invalid response from Xend, twice.
nn1 xen # xm list
