Hey Jaime

okay i use a laptop with:
Intel® Virtualization Technology (VT-x) 
(http://ark.intel.com/products/53469)
Intel® Virtualization Technology (VT-x) allows one hardware platform to 
function as multiple “virtual”
platforms. It offers improved manageability by limiting downtime and 
maintaining productivity by isolating
computing activities into separate partitions.

i use this laptop as the host i installed:

apt-get install virt-manager kvm libvirt-bin qemu

and built with the virt-manager a virutal machine and on this i 
installed opennebula and sunstone

my output on that virtual machine as oneadmin is:

oneadmin at kvmserver-vm:~$ grep -oE 'svm|vmx' /proc/cpuinfo
vmx
vmx

------------------------------------------------------------------------

oneadmin at kvmserver-vm:~$ virsh -c qemu:///system capabilities

   </host>

</capabilities>

okay it seems to be a miss configuration do you know what i have to 
change...

i made this following changes:

for ssh:

Configure not to ask before adding hosts to known_hosts file.
Look into ~/.ssh/config, see man ssh_config for a complete reference.
# nano /etc/ssh/ssh_config
StrictHostKeyChecking no

and

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]
change the unix_sock_rw_perms = "0777"
uncomment:
unix_sock_dir = "/var/run/libvirt"

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

and i restarted libvirt-bin as root and opennebula and sunstone as 
oneadmin

thanks

Johannes
