Re: [Xen-devel] ZFS version for pygrub

[Boris Derzhavets <bderzhavets@xxxxxxxxx>]

Link provided bellow would work for sure at Xen 4.0 Dom0 with pvops kernel 2.6.32.10 (11) on top of F12 or Ubuntu 9.10 Server.

http://bderzhavets.wordpress.com/2010/04/11/set-up-osol-2010-03-build-134-at-xen-4-0-2-6-32-10-pvops-kernel-on-of-ubuntu-karmic-koala-server/

I suspect that problems with MRJ's ZFS 24 patch for pygrub&fsimage.iso
are connected with broken NWAM at least on OSOL 134.
In other words,  patch itself might be fine. DHCPDISCOVER stops working
after first boot up configuring SMF and requires restart of service
  # svcadm restart svc:/network/physical:nwam
after login to obtain IP for DomU, what has nothing in common with patch mentioned above. I attempted to use patched pygrub only to load already created image. Pygrub at Xen 4.0 has problems with reading ISO images in general.
The issue might be specific for my environment as well.

remove the kernel and ramdisk line above. e.g.

 bootloader = "/usr/bin/pygrub"

 extra = "/platform/i86xpv/kernel/amd64/unix -B console=ttya,livemode=text"
 memory = 512 

MRJ

Using config file "./ns.pv_i".

Error: Boot loader didn't return any data!
