Hi Humberto, Just a guess.
What the output of the command 'grep nodeinfo_text $ONE_LOCATION/lib/remotes/im/kvm.d/kvm.rb|grep virsh' on front-end node?
I have nodeinfo_text = `virsh -c qemu:///system nodeinfo` But it looks like you should change it to virsh -c qemu+ssh:///system HTH, Nikolay. Humberto N. Castejon Martinez wrote on 21/09/11 19:21:
Hi, I know the problem I am going to report has already been discussed, but what I have read from previous discussions has not helped. My Opennebula front-end has problems to monitor one of my hosts. I get the following log messages: Wed Sep 21 17:03:44 2011 [InM][I]: Command execution fail: 'if [ -x "/var/tmp/one/im/run_probes" ]; then /var/tmp/one/im/run_probes kvm joker; else $ Wed Sep 21 17:03:44 2011 [InM][I]: STDERR follows.

Wed Sep 21 17:03:44 2011 [InM][I]: Permission denied (publickey,password).

The first thing that I have noticed is that run_probes is not in /var/tmp/one/im/, but I have it in /srv/cloud/one/lib/remotes/im/. Can that be the source of the problem? If I executed from my front end machine the following command as root, everything seems to work ok: /srv/cloud/one/lib/remotes/im/run_probes kvm joker However, if i execute it as oneadmin, i get the following error: Connecting to uri: qemu:///system error: unable to connect to '/var/run/libvirt/libvirt-sock': Permission denied error: failed to connect to the hypervisor Error executing kvm.rb ARCH=x86_64 MODELNAME="Intel(R) Xeon(R) CPU E5540 @ 2.53GHz" I have checked, and oneadmin is member of the cloud group in joker, I have specified unix_sock_group = "cloud" in /etc/libvirt/libvirtd.conf and libvirt-sock seems to have the right permissions: srwxrwx--- 1 root cloud 0 2011-09-21 17:02 /var/run/libvirt/libvirt-sock So i do not know why I get the "permission denied" message. However, if I run virsh -c qemu+ssh://oneadmin@joker/system, I manage to connect to virsh, w/o entering a password. So i do not really know what the problem is, and hope you can help me. The funny thing is that it used to work perfectly, but it stopped working suddenly, without me changing anything (or at least I think so).
