[one-users] OpenNebula 3.4.1 - Error creating host for kvm

[Mohit Dhingra]

Hi,

Thanks for your reply. /var/run/libvirt/  was accesible to the oneadmin.
Going through the further search, we found the following:

When we run the following executable, ( which is called by kvm.rb

oneadmin at cloud:/var/tmp/one/im> ./run_probes kvm 21 cloud
error: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may
need to be started: Connection refused
error: failed to connect to the hypervisor
ERROR MESSAGE --8<------
Error executing kvm.rb
ERROR MESSAGE ------>8--
ARCH=x86_64 MODELNAME="Six-Core AMD Opteron(tm) Processor 2431"
oneadmin at cloud:/var/tmp/one/im>


Socket file is already there, created by root.
srwxrwxrwx 1 root cloud 0 May 10 18:03 /var/run/libvirt/libvirt-sock

We are not sure how to do the following (in documentation -
http://www.opennebula.org/documentation:archives:rel3.0:kvmg )
To be able to use the images copied by OpenNebula, change also the user and
group under which the libvirtd is run to “oneadmin”.

We tried restarting libvirtd as oneadmin,

oneadmin at cloud:/var/tmp/one/im> /etc/init.d/libvirtd restart
Shutting down libvirtd                                              done
Starting libvirtd                                                   done

Still, it didn't work. Any other clues?
