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! hxk _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
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
