<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi Ruben,<br><br>I am using the OpenSUSE package (installed through
YaST). Just to make sure that I did the configurations right (I'm sure I
didn't):<br><br>At (I quote from the documentation): "To be able to use
the images copied by OpenNebula, change also the user and group under
which the libvirtd is run to “oneadmin”", what exactly needs to be done?
I am a Linux-noob (or at least, not at all an expert), so forget me
this question, but how do I set the user and group under which a daemon
is run? I have checked under which user is the libvirtd daemon is
currently running, and indeed it is root (since I probably set it and
put it in init.d as the root user).<br><br>Also: "(typically <code><oneadmin></code>) has to pertain to the <libvirtd> and <kvm> groups in order to use the daemon and be able to launch VMs."<br>What are the
<libvirtd> and <kvm> groups? And how how do I achieve the necessary configuration?<br><br>I did some configuration, but I just want to make sure that I'm not missing anything (which I probably do).<br><br>Ruben? Anyone? <br><br>Thank you,<br>Lehel.<br><br>--- On <b>Fri, 3/9/12, Ruben S.

as I mentioned at the bottom of my previous email, I already run /var/tmp/one/im/run_probes with the necessary parameters on pcls (my only host), which resulted in the same (empty) output.

<br>I didn't try 'onehost sync', but I could try tomorrow morning (since I got home already, and I'm not at the respective computers), if you consider that it might help.<br><br>Any other suggestions?<br>
