First of all i thanks Lozz for his negative score, which has stirred up my mind.Set up Xen 4.0 Dom0 with pvops kernel 2.6.32.12 on top of Ubuntu 10.04 Server ([2]) . Install packages
# apt-get install virtinst python-virtinst virt-viewer
It’s important to specify "--connect xen:///" inside virt-install command line to succeed with VNC console launching (vs 9.10) . Variable VIRSH_DEFAULT_CONNECT_URI="xen:///" exported via .bashrc in my case caused virt-install to crash. In other words virt-install
doesn't understand this export on 10.04

fix block_stats for xen/pvops kernel
As stated in http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1454
"/sys/devices/xen-backend/" changed to "/sys/bus/xen-backend/".
Therefor libvirt (virsh, virt-manager, ...) are unable to report storage backend performance numbers. This seems to be true for all new Xen pv-ops kernels (2.6.3X)
The attached patch tries to fix this by appending that path to "read_bd_stat" in "src/xen/block_stats.c".
