Re:Re: [Xen-devel] some errors of pvonhvm : xen-blkfront



thanks for your time
the version of ubuntu 10.10 is 2.6.35.

the domU can boot successfully, but when I operate some commands such 
as :ls ,touch , it'll be blocked, just like I stated before.

I have another question:
      when I debug the xen-blkfront, I found the most difficult thing 
is debug it. I want to know can I use xen-blkfront substitute a slave 
disk, not the boot disk(primary disk), thus I can boot the system on qemu emulated disk, and then mount the xen-blkfront disk, then to debug it. Can I do this???
      waiting...
