Hi, Juan
Thank you for your comments.
I can boot domU with the following modprobe.conf.
alias scsi_hostadapter xenblk
But I have some ide errors.
After I add extra = 'ide0=noprobe ide1=noprobe ide2=noprobe ide3=noprobe
ide4=noprobe' into domU's config, ide errors are not occurred.
(Thanks Kouya)
Best Regards,
Akio Takebe
