*Hello,* * * *My environment is "Xen3.1 in Fedora8" with "libvirt0.3 & python2.5". When I ran the following * *commands as a non-root user "nimbus":* $python

...

...

import libvirt libvirt.open("xen:///")

...

...

import libvirt libvirt.open("xen:///") Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.5/site-packages/libvirt.py", line 123, in open if ret is None:raise libvirtError('virConnectOpen() failed')

*I encountered the error "virConnectOpen() failed". if I changed the user into root, it worked well. * *But I hava to use the non-root account "nimbus". I looked into the problem on the net, in order * *that non-root user could use libvirt as root user, someone suggested that I should modify the libvirt * *configuration file "/etc/libvirt/libvirtd.conf", but they didn't point out what field should be changed.* * * *I am puzzled about that problem. I have already changed the sudo file and the xen configuration * *file "/etc/xen/xend-config.sxp", which doesn't work at all. Could someome give me any tips? * --------- "/etc/xen/xend-config.sxp" --------- (xend-http-server yes) (xend-unix-server yes) (network-script network-bridge) * * *Thanks in advance!* * * *Cheers,* * * *Shenglan Wang*
