I have a 64bit cpu with Centos 6.6 as the O/S. I am trying to get Virualization up and working and am having a problem. I had to go to the System/Administration/ADD/Remove software to load the Virtualization files and then i ran the load for Qemu-kvm, python-virstinst, virt-manager, virt-top, virt-viewer, libvirt, and libvirt-client.
Some of them didn't load up I beleive because they were there. Some did load. then I start the Virtual Machine Manager, enter the password, and when the window opens I select the localmachine and then do an ADD connection option and I select the "connect to remote host option" and it has ssh in there and username 'root' and then hostname i put rybo-vm.
I check the "autoconnect" box and hit connect. I then get this ERROR:
Unable to open a connection to the libvirt management daemon.
Libvirt URI is: qemu+ssh://root@rybo-vm/system
Verify that:
- The 'libvirtd' daemon has been started
Cannot recv data: ssh: Could not resolve hostname rybo-vm: Name or service not known: Connection reset by peer
Traceback (most recent call last):

flags)
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 102, in openAuth
if ret is None:raise libvirtError('virConnectOpenAuth() failed')
libvirtError: Cannot recv data: ssh: Could not resolve hostname rybo-vm: Name or service not known: Connection reset by peer
The error is quite self-explanatory - the client software (virt-manager) cannot connect to the backend server (libvirtd).
If you are trying to connecto to a local machine, you need to use localhost
If you are actually trying to reach another host, then you should check connectivity (network/ports/firewall/etc) and the actual backend daemon, i.e. verify libvirtd is up and running
