If making an initrd does not work, then it's possible that your dom0 kernel build does not build all of the correct modules. You should be able to retrieve a kernel .config file for the non-Xen kernel (ideally, the distro would have a specific .config for a Xen dom0, which I know is the case for FC5), and use this as the configuration for building your dom0 kernel. Then try making an initrd as before. Hope this helps. Regards, Derek. On 30 May 2007, at 02:50, Mark Williamson wrote: Are you using an initrd in the guest? Is your distro expecting you to useone?Boot the guest non-Xen, then you can use mkinitrd to generate one for yourdom0 kernel and modify the grub.conf / menu.lst accordingly.

For the HVM domainI am using a file-backed block device to hold the file system, so the config file contains one line: disk = [ 'file:path/imgfile, ioemu:hda, w' ] But when I boot Xen-unstable in the HVM domain, I got the following panic message: Xen virtual console successfully installed as ttyS0 Event-channel device installed. ...

It looks like that the internal dom 0 Linux (Red Hat nash version5.1.19) does not recognize the disk device emulated by the external Xen.This is because I can boot Fedora Core 6 in the same HVM domain, and from dmesg I can see that the emulated disk was recognized as 'QEMUHARDDISK, ATA DISK drive', but in the above message I can not see thisline. So my question is: How do I configure the dom0 Linux coming withXen-unstable so that it can recognize the emulated disk? Am I missing adevice driver for this QEMU HARDDISK? Thanks!
