RE: [Xen-users] I've exhausted my brain trying to get xen toboot...pleas
Miguel,
It sounds like you might be getting a kernel panic. To prevent the
machine from rebooting after the error message displays, you can try
specifying that Xen not reboot by appending 'noreboot' to Xen's entry in
grub.conf (See section 10.3 of the xen manual).
Earlier this week, I also thought I was not compiling the correct
drivers in to the kernel, but it turns out that the drivers in 2.6.18
did not support my hardware (Intel's ICH9 chipset). I had to patch a
few source files and recompile. What does the output of 'lspci' and
'lspci -n' look like?
The build instructions you listed are for building a custom dom0 kernel.
To build just the Xen hypervisor, I believe you have to do 'make
install-xen' from the root xen directory.
