What is your base distro ?

You should not have problems with Xen 3.4.2 , Libvirt 0.7.1-15 on top of F12 and
recent JF's 2.6.31.6 pvops kernel.

Activate rpmbuild via:-
|
# yum install transfig texi2html libaio-devel dev86 glibc-devel.i686 e2fsprogs-devel gitk mkinitrd
|
Build Xen rpms
|
# rpm -iv xen-3.4.1-5.fc13.src.rpm
In mean time:
# ||rpm -iv xen-3.4.2-2.fc13.src.rpm|
|# cd rpmbuild/SPEC
# rpmbuild -ba ./xen.spec
# cd ../RPMS/x86_64
|
Install Xen Hypervisor & tools ( rpms names and number would obviously
   changed for 3.4.2-2)
||
|[root@fedora12sda x86_64]# cat inst.sh
yum install xen-3.4.1-5.fc12.x86_64..rpm \
xen-debuginfo-3.4.1-5.fc12.x86_64.rpm \
xen-devel-3.4.1-5.fc12.x86_64.rpm \
xen-doc-3.4.1-5.fc12.x86_64.rpm \
xen-hypervisor-3.4.1-5.fc12.x86_64.rpm \
xen-libs-3.4.1-5.fc12.x86_64.rpm \
xen-runtime-3.4.1-5.fc12.x86_64.rpm
|

Install Libvirt
|
# yum install libvirt libvirt-python python-virtinst \
virt-manager virt-viewer|

Boris.
P.S. Don't touch /etc/fstab. xenfs be would mounted automatically

    I'm running the 2.6.31.6 pv_ops dom0 kernel, libvirt 0.7.0 and Xen
    3.4.1.

    When I try connecting to the Xen hypervisor using virsh it gives me a
    "Connection refused":

    root@grp-01-23-02:~# xm list
    Name                                        ID   Mem VCPUs      State

    Domain-0                                     0  1020     4     r-----
    858.3

    root@grp-01-23-02:~# virsh -c xen:/// list
    Connecting to uri: xen:///
    error: unable to connect to 'localhost:8000': Connection refused
    error: failed to connect to the hypervisor


    How can I get virsh to connect with Xen?

    Also, this machine had KVM kernel originally.  So are there some
    configuration changes needed to support xen?

My base distro on this machine is Ubuntu 9.10 Server. And I did pretty much the same thing for it as you did for F12. I built debs for Xen 3.4.1 and installed them, custom built the JF pv_ops dom0 kernel and installed it. Libvirt was already installed at version 0.7.0 so I didn't touch it. libvirt had worked fine for a few test KVM guests. But now I want the whole machine dedicated to Xen guests but I'd still like to use libvirt to manage the guests. So how do I get 'virsh' to default to the xen:/// hypervisor and also how do I get it to connect to it? There's nothing running on port 8000. So this is a mystery.
