Default virt-manager error in Fedora8+xen3.2

Hi
*
I'm sorry for this repeated question, but i failed to start my virt-manager in Fedora8+xen3.2, error shows like:


Unable to open connection to hypervisor URI 'xen:///':
<class 'libvirt.libvirtError'> virConnectOpenReadOnly() failed
Traceback (most recent call last):
* File "/usr/share/virt-manager/virtManager/connection.py", line 307, in _open_thread

*** self.vmm = libvirt.openReadOnly(self.uri)
* File "/usr/lib/python2.5/site-packages/libvirt.py", line 148, in openReadOnly
*** if ret is None:raise libvirtError('virConnectOpenReadOnly() failed')

libvirtError: virConnectOpenReadOnly() failed


I download and install xen3.2 on Fedora8 successfully.


There is always a warning ask me to disable tls in /lib/tls before the OS begining, though*making initrd.img after mv /lib/tls /lib/tls.disable and i*am sure the Dom0 works well. I use "yum install virt-manager" to setup virt-manager and it should be the lastest version. I restart the xend with no error.



Is there a compatiable error using xen3.2 and virt-manager? Or the /lib/tls do bad to my virt-manager? Any patches?


Beg for any replies, thanks.


Oscar

Ignore the /lib/tls warning - that hasn't been relevant for years. You
probably don't have Xend listening for connections. You need

(xend-unix-server yes)

Set in /etc/xen/xend-config.sxp
