<table border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font:inherit;" valign="top">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>
