[Fedora-xen] RE: [Xen-ia64-devel] [Fedora-ia64-list] FC6 Test3 Xen test result

Hi, Yongkang

I think this issue is configuration mistakes.
Can you try the following configuration?
I cannot try it because I meet another issue...

1. /etc/modprobe.conf for initrd of domU
The following configuration would solve the issue of booting domU.
    [root at tiger156 xen]# cat /etc/modprobe.conf 
    #alias eth0 e1000
    #alias scsi_hostadapter mptbase
    #alias scsi_hostadapter1 mptspi
    alias eth0 xennet  <----this
    alias scsi_hostadapter xenblk <----and this

2. domU.conf
The following configuration would solve the issue of probing ide disk.
    kernel = "vmlinuz-2.6.17-1.2630.fc6xen"
    ramdisk = "initrd-2.6.17-1.2630.fc6xenU.img"
    memory = 512
    name = "domU"
    vif = [ '' ]
    disk = [ 'file:/xen/image/fc6.root.img,hda1,w' ]
    root = "/dev/hda1 ro"
    extra = "3 ide0=noprobe ide1=noprobe ide2=noprobe ide3=noprobe" <----this

Best Regards,

Akio Takebe
