Re: [Xen-users] virsh -c xen:/// list: = Connection refused
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:~# virsh -c xen:/// list
Connecting to uri: xen:///
error: unable to connect to ''localhost:8000'': Connection

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?

Re: [Xen-users] virsh -c xen:/// list: = Connection refused
I participated it bug thread regarding virt-install failure on Ubuntu 8.04 Server ( Xen 3.2 was still there, the last xen enabled release) . It was a while ago and i don''t remember the number . There was no valuable answer at all. Canonical seemed to forget what the Xen was. If i am wrong about that and latter they fixed libvirt to support Xen, it would be fine. You may post it as "bug" or "RFE" on Launchpad and see what they respond. In meantime i am aware of only two Libvirt''s implementations supporting Xen 3.4.2. 1. OpenSolaris 2010-02 xVM 3.4.2 ( libvirt 0.7.0) There is a good chance that in 1-2 months it might become enterprise class system, regardless ongoing issues with VNC on build 130. 2010-02 should be build 132. 2. F12,F11 Xen 3.4.2(1) ( libvirt 0.7.1-15), but no enterprise class kernel to support Dom0 for hardly predictable period of time.
