Install Xen 4.0 and Libvirt like on F12 ([1]). Via my experience xend will hang for 5-7 min at startup and xen managed bridging will fail as well .At the same time PV guests won’t be able to obtain IP via interface virbr0. Workaround for the issue follows bellow.

http://bderzhavets.wordpress.com –
Due to ongoing issue with virsh compiled against libvirt 0.7.5 when working with Xen 4.0 Hypervisor. I attempted to downgrade libvirt and related stuff to Ubuntu Karmic’s ( well tested version with Xen). Proceed as follows :-
1.Edit /etc/apt/sources.list

Completely functional virsh (Libvirt 0.1.7-15) & GRUB2 Support at Xen 3.4.3 on top of F12

Recent pulling GRUB2 supporting CSs into xen-3.4-testing.hg immediately makes sense to build xen 3.4.3-2.fc12.src.rpm to be able to set up current version of 3.4.3 Xen Hypervisor on Fedora 12 working pretty smoothly with Libvirt packages ( vs Xen 4.0) and the at same time supporting GRUB2 PV DomUs , say Ubuntu 9.10 Server or Debian Sqeeze.

Virsh ( Libvirt 0.7.2) & managing DomUs on openSUSE 11.2
http://bderzhavets.wordpress.com –
Recent “zypper update” on November’s openSUSE 11.2 release brought system to the most recent status. Current 2.6.31.8-xen kernel works fine.Seems like a next generation of xen-ified aka Suse kernels is on the go right now. However, i believe,that vm-install on recently updated 11.2 works same way as before maintenance update.
