Dear all, 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.
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. 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? Here is the initial part of oned.log, highlighted with the errors: Wed Apr 18 16:24:58 2012 [ONE][I]: Starting OpenNebula 3.2.0 ---------------------------------------- OpenNebula Configuration File ---------------------------------------- AUTH_MAD=ARGUMENTS=--authn ssh,x509,ldap,server_cipher,server_x509,EXECUTABLE=one_auth_mad DB=BACKEND=sqlite DEBUG_LEVEL=3 DEFAULT_DEVICE_PREFIX=hd DEFAULT_IMAGE_TYPE=OS ENABLE_OTHER_PERMISSIONS=YES HM_MAD=EXECUTABLE=one_hm HOST_MONITORING_INTERVAL=600 HOST_PER_INTERVAL=15 IMAGE_MAD=ARGUMENTS=fs -t 15,EXECUTABLE=one_image IM_MAD=ARGUMENTS=-r 0 -t 15 kvm,EXECUTABLE=one_im_ssh,NAME=im_kvm MAC_PREFIX=02:00 MANAGER_TIMER=15 NETWORK_SIZE=254 PORT=2633 SCRIPTS_REMOTE_DIR=/var/tmp/one SESSION_EXPIRATION_TIME=900 TM_MAD=ARGUMENTS=tm_shared/tm_shared.conf,EXECUTABLE=one_tm,NAME=tm_shared VM_DIR=/var/lib/one/ VM_MAD=ARGUMENTS=-t 15 -r 0 kvm,DEFAULT=vmm_exec/vmm_exec_kvm.conf,EXECUTABLE=one_vmm_exec,NAME=vmm_kvm,TYPE=kvm VM_PER_INTERVAL=5 VM_POLLING_INTERVAL=600 VNC_BASE_PORT=5900 ---------------------------------------- Wed Apr 18 16:24:58 2012 [ONE][I]: Log level:3 [0=ERROR,1=WARNING,2=INFO,3=DEBUG] Wed Apr 18 16:24:58 2012 [ONE][I]: Checking database version.

Any suggestion would be highly appreciated. Thank you, Lehel.
