Thread-topic: [Xen-devel] Xen-Qemu

  Hello all,

   I have a goal to run Xen on Qemu (Basically qemu give an emulated platform as ARM in my case).

   I have done some experiment for- Xen to run on qemu ( for i-386 platform)

   There is a problem- on the run time we pass parameters such as:

   shell# qemu -kernel xen-3.1.gz -initrd initrd-2.6.18-xen -hda disk.img -append "root= as per your root file system on disk.img"

   there are much more option we can see qemu --help.

   But to boot xen there are three entry in /boot/grub/grub.conf

   title Fedora (2.6.20-2925.9.fc7xen)
        root (hd0,1)
        kernel /boot/xen.gz-2.6.20-2925.9.fc7
        module /boot/vmlinuz-2.6.20-2925.9.fc7xen ro root=LABEL=/ rhgb quiet
        module /boot/initrd-2.6.20-2925.9.fc7xen.img

   But we can't pass module --in qemu , i am not sure if any one correct me??
   I execute this:

   qemu -m 128  -kernel xen-3.1.0.gz -initrd initrd-2.6.18-xen.img  -hda disk.img -append "root=/dev/VolGroup00/LogVol00"
   Error Log:
qemu: fatal: Trying to execute code outside RAM or ROM at 0x000a01a9
