Hi,
I install xen 4.1.2 on centos 6 with linux kernel 3.0.4 as dom0 kernel.
When I launch virt-manager on the command line ,a window pop up which show the
following error:
Unable to open a connection to the Xen hypervisor/daemon.
Verify that:
- A Xen host kernel was booted
- The Xen service has been started
Details: Unable to open connection to hypervisor URI
''xen:///'': no connection driver available for xen:///
Traceback (most recent call last): File
"/usr/share/virt-manager/virtManager/connection.py", line 992, in
_try_open None], flags) File
"/usr/lib64/python2.6/site-packages/libvirt.py", line 111, in openAuth
if ret is None:raise libvirtError(''virConnectOpenAuth()
failed'') libvirtError: no connection driver available for xen:///
Then I was going to confirm that in the file "xend-config.sxp"
(xend-http-server yes) and (xend-unix-server yes) are uncommented. But this
error occured again.
Perhaps on redhat 6.0 virt-manager doesn''t work well .But is there the
same problem with centos 6.0 ?Now I don''t know how to solve it. Please
help!

I don''t have a fix, but I too hit this problem on CentOS 6 running Xen 4.1.1 and 2.6.32-46 for the dom0.

Please help!For most packages, Centos simply builds redhat''s SRPM. They''ll have the same sets of features (and depending on how you look at itt, bugs) -- Fajar
