<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Dear all,<br><br>In my ONE system, sometimes, after the front-end's startup, I've noticed that the KVM drivers (vmm_kvm and im_kvm) are not able to load. At first I didn't understand what could be causing such ONE malfunction, but soon I tracked back all related errors and found the answer in the very initial part of oned.log, which I copied at the end of this mail.<br><br>It seems to be a strange issue, since it apparently happens rather randomly, sometimes a reboot of the front-end makes the issue disappear, but sometimes the error just sticks.<br><br>I'm aware that it might possibly not be an ONE issue. However, I would be extremely grateful if you could provide some hints or point-outs to where should I at least be looking for the cause of this problem. Is this a front-end issue? Is this an issue with the respective host? Both have KVM installed and I've
performed virtualizations on both of them (with virsh+qemu) since my ONE infrastructure is up. Are there any logs which I could check to possibly find more detail?<br><br>Here is the initial part of oned.log, highlighted with the errors:<br><br>Wed Apr 18 16:24:58 2012 [ONE][I]: Starting OpenNebula 3.2.0<br>----------------------------------------<br> OpenNebula Configuration File <br>----------------------------------------<br>AUTH_MAD=ARGUMENTS=--authn ssh,x509,ldap,server_cipher,server_x509,EXECUTABLE=one_auth_mad<br>DB=BACKEND=sqlite<br>DEBUG_LEVEL=3<br>DEFAULT_DEVICE_PREFIX=hd<br>DEFAULT_IMAGE_TYPE=OS<br>ENABLE_OTHER_PERMISSIONS=YES<br>HM_MAD=EXECUTABLE=one_hm<br>HOST_MONITORING_INTERVAL=600<br>HOST_PER_INTERVAL=15<br>IMAGE_MAD=ARGUMENTS=fs -t 15,EXECUTABLE=one_image<br>IM_MAD=ARGUMENTS=-r 0 -t 15
