Re: [Xen-ia64-devel] [Patch] booting Guest domains w/o initrd on RHEL4

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi all

I'm sorry.
I have not been able to boot completely yet.

DomU's booting stoped at the below point. :<

ALSA device list:                                                         
                
  No soundcards found.

Does anyone have the same problem?
