Hi all,

New to this list.

I built xen-4.1.1 successfully and can see that it boots from grub with the kernel /xen.gz line.

I'm using the following kernel (3.0.0-rc2):

http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git and its default .config file,

which also builds successfully and boots standalone.

When I try to boot it as a dom0 I get a segfault.

There is nothing in any of the logs (probably segfaults very early) and I can't even see the tail end of the segfault because the screen blanks afterward, even though I specify noreboot on the module "kernel" line.

Here's my boot stanza:

title FedoraXen (4.1.1-3.0.0-rc2)
        root (hd0,0)
        kernel /xen.gz
        module  ### all on one line
          /vmlinuz-3.0.0-rc3
          ro
          root=/dev/mapper/vg_lan51-lv_root
          rd_LVM_LV=vg_lan51/lv_root
          rd_LVM_LV=vg_lan51/lv_swap
          rd_NO_LUKS
          rd_NO_MD
          rd_NO_DM
          LANG=en_US.UTF-8
          SYSFONT=latarcyrheb-sun16
          KEYBOARDTYPE=pc
          KEYTABLE=us
          console=tty0
          xencons=hvc
          console=hvc0
          dom0_mem=752M
          noreboot
        module /initramfs-3.0.0-rc2.img

If anybody can point me in some direction where I can capture additional info or give me any pointers I'd be most appreciative.

Thanks,
Mike Wright
