| Everything has been done from scratch and seems to be working. ZFS support patches added to src.rpm and installed, libvirt packages installed . Xen 3.3.1 F10 Dom0 ( 2.6.30-rc3-tip) does have ZFS support and virt-install ( virt-manager) connects to xend and may be used for DomUs management.

 | Yes , i was able to add ZFS support and manage OpenSolaris DomUs. I was still able to manage Linux DomUs , using two pygrub profiles :-
 first one to install DomU , second one to load and run. Same way as in case of
 building Xen Unstable Dom0 with pvops kernel on Ubuntu 8.10 server.
 But, reinstalled libvirt,libvirt-python,python-virtinst,virt-manager and virt-viewer
 i was unable to reconnect to xend via both tools..
 In meantime I am not sure was it an accident or it was supposed to happen.
 In second case direct port Xen Unstable to F10 ( without libvirt, there is xen-lib package dependency what prevents proper porting ) is obviously a preferable solution.

 | I believe that , xen-backport-hg18782.patch from ./rpmbuild/SOURCES is exactly raw content of change set 18782 from xen-unstable.hg
 I am not sure would be adding
 xen-backport-hg19322.patch (libfsimage: Support for zfs version 14.)
 xen-backport-hg19323.patch (pygrub:
 Workaround for Solaris CR 1143256)
 sufficient to to get properly ZFS support and pygrub
 backported  to Xen 3.3.1 for Fedora.
 I may be missing some more cs's to complete the task.
 Please, advise.
 
 Boris.
