Re: Re: Re: Re: Re: Re: Re: [Xen-users] xen-3.0-x86_32 not supp

Hi, Nick:
I have found the answer. The image file rh9.img should be formated using mkfs.ext3 of RH9, not mkfs.ext3 of RHEL AS5.1.
Thank you so much!
Joe

The domUs, on the other hand, load drivers that allow them to use the devices exported by dom0 (or by a stub domain, in the case of Xen 3.3).  So, your dom0 will use an IDE driver or SCSI driver, while the domU needs xenblk to operate correctly.
