Hi,

My Environment :

Frontend and host : centos 6.4
Opennebula version : 4.2

Tue Nov 19 13:58:16 2013 [VMM][I]: Command execution fail: cat << EOT |

Here are some other details :

[root at kpkvm1 56]# grep -vE '^($|#)' /etc/libvirt/qemu.conf
user  = "oneadmin"
group = "oneadmin"
dynamic_ownership = 0



[root at kpkvm1 58]# grep -vE '^($|#)' /etc/libvirt/libvirtd.conf
[root at kpkvm1 58]#


[root at kpkvm1 58]# cat
/etc/polkit-1/localauthority/50-local.d/50-org.libvirt.unix.manage-opennebula.pkla
[Allow oneadmin user to manage virtual machines]
Identity=unix-user:oneadmin
Action=org.libvirt.unix.manage
#Action=org.libvirt.unix.monitor
ResultAny=yes
ResultInactive=yes
ResultActive=yes






[root at kpkvm1 58]# id oneadmin
uid=9869(oneadmin) gid=9869(oneadmin) groups=9869(oneadmin)


[root at kpkvm1 58]# cat /etc/libvirt/qemu.conf
user  = "oneadmin"
group = "oneadmin"
dynamic_ownership = 0


I tried changing dynamic_ownership to 1 , started libvirtd and oned and
again tried creating the vm
sudo -u oneadmin virsh -c qemu:///system create deployment.0
it gives the same error
error: Failed to create domain from deployment.0
error: internal error process exited while connecting to monitor: qemu-kvm:
