[one-users] failed to connect to the hypervisor

[cloud.b.lab]

Susmita ,

some tips from a OpenNeula user:

Please cross check the following for "error: unable to connect to '/var/run/libvirt/libvirt-sock', libvirtd may need to be started: Permission denied"  :

1)
edit file: /etc/libvirt/libvirtd.conf as make following changes:
unix_sock_group = "oneadmin" [if you have given a different name for the group like "cloud" , provide that]


edit file: /etc/libvirt/qemu.conf and make following changes
vnc_listen = "0.0.0.0"
user = "oneadmin"
group = "cloud"
dynamic_ownership = 1

then restart libvirt as root : /etc/init.d/libvirt-bin restart

try VM creation.

If the issue still exists then,

2) Make following change in file: /etc/libvirt/libvirtd.conf
unix_sock_rw_perms = "0777" then restart libvirt as root : /etc/init.d/libvirt-bin restart 
sudo chown oneadmin:kvm /dev/kvm
try VM creation. 
Regards,
Anil.

Please check that libvirtd is running and that the oneadmin user has 
permissions to connect to the libvirt socket. This permissions can be 
adjusted in /etc/libvirt/libvirtd.conf or somewhere similar in Ubuntu i 
guess.
