I did install Xen on Fedora 10 ,
it seems that xen is not fully installed,
When running xen I receive a message error:
Unable to open connection to hypervisor URI ''xen:///'':
<class ''libvirt.libvirtError''> unable to connect to
''localhost:8000'': Connection refused
None
But when going on GUI, I can see the virtrual manager but
can not use it.
click on menu bring no reactions?
Can someone help?
Thanks ,
Mark

Try running ''service xend status'' and see if the daemon is running. If not, you need to start it with ''service xend start'' and try again. I believe libvirt uses Xen''s API, which is disabled by default in some distributions (look at /etc/xend/xend-config.sxp to enable it; it''s well-commented so you''ll be able to figure it out fairly easily). Just so you know, we had a lot of problems installing Xen on Fedora (F11, x86_64) and have since moved to CentOS, which seems to be the best distribution in terms of stability and Xen. Hope this helps, Luke.

So you cannot use Xen in Fedora before you install dom0 kernel. -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Install Dom0 kernel itself doesn''t provide a warranty for virsh to be able to connect to xend daemon. If you still would not be able to connect via virsh to xend, ( what is not supposed to happen if Xen Hypervisor installed via xen-3.4.2-2.fc13.src.rpm ) make sure :- 1. (xend-unix-server yes) is uncommented and issue : # service xend restart 2.~/ .bashrc contains entry export VIRSH_DEFAULT_CONNECT_URI="xen:///" Boris. --- On Mon, 2/8/10, Pasi Kärkkäinen <pasik@iki.fi> wrote: From: Pasi Kärkkäinen <pasik@iki.fi> Subject: Re: [Xen-users] install xen on fedora ?

In general , procedure to set up Xen 3.4.1 & Libvirt 0.7.1-15 on F12 (with JF''s pvops kernel to support Dom0) may be viewed in details :- http://bderzhavets.wordpress.com/2009/11/22/setup-ubuntu-9-10-server-pv-domu-at-xen-3-4-1-dom0-2-6-31-6-pvops-kernel-on-top-of-fedora-12/ Only one notice, install Xen via xen-3.4.2-2.fc13.src.rpm, posting above is a bit out dated. Due to Libvirt install without KVM, there is no need to point to default Hypervisor on F12 versus my previous message where same setup has been done on Ubuntu 9.10 Server. I just couldn''t aptitude install Libvirt without qemu-kvm package on mentioned box, what caused :- # export VIRSH_DEFAULT_CONNECT_URI="xen:///" to be required.
