Hi,<br><br>As far as I know, oneadmin execute commands using sudo, you need to specify which command oneadmin is allowed to run in /etc/sudoers. and also, no password should be asked when it use sudo. for instance, if you add following, you let it run any command with sudo, without any password required:<br>
<br>oneadmin ALL=(ALL) NOPASSWD: ALL<br><br><br>add this line to /etc/sudoers, then try to modify your bridge using oneadmin user.<br><br>pleas also attach latest logs in /var/log/one/oned.conf when you face the error message<br>

Hello,<div><br></div><div>I can't give you much advice on Centos 5.5 since it's not officially supported any more and we haven't used it for a while. However, it seems your problem can be solved by properly configuring /etc/libvirt/libvirtd.conf and /etc/libvirt/qemu.conf</div>
<div><br></div><div>Have you followed the KVM guide (dynamic ownership, setting oneamdin as the user, etc):</div><div><a href="http://opennebula.org/documentation:rel3.4:kvmg" target="_blank">http://opennebula.org/documentation:rel3.4:kvmg</a></div>

hi,<br>
has anyone successfully configured KVM on CentOS 5.5 for OpenNebula?<br>
<br>
I have an issue with the interface create at VM startup.<br>
<br>
Failed to add tap interface to bridge 'br0': Operation not permitted<br>
<br>
I know commands on Debian, but I cannot find how to do this on Centos<br>
(give non root user permissions to add a tap to the bridge).<br>
I added a rule : KERNEL=="tun", NAME="net/%k", GROUP="kvm", MODE="0660"<br>
<br>
but it does not seem to be enough....<br>
<br>
Thanks<br>
