Peter, Thanks for the reply. Just to let you know turning off TLS did not solve the issue for me. I have netcat and the user I am trying to login to virsh console does have privileges to create socket. Enabling debug while I try to login using QEMU+SSH, I get prompted for my password and get the following debugs. The error message "Failed to connect to the hypervisor" looks a little suspicious. The same uri with a prebuilt virsh binary, does not have any issues connecting. Any thoughts? shanredd@xxxxx.cisco.com's password: 2013-03-06 17:30:25.993+0000: 28966: debug : virNetClientMarkClose:631 : client=0x1c52b10, reason=0 2013-03-06 17:30:25.993+0000: 28966: debug :

Hi Shantan,
I believe the problem may be that libvirt 1.x requires TLS by default on connections. I saw that same problem the 1^st time I replaces a running libvirt 0.9.x with 1.0.0. I believe there may be a way to turn off this requirement in libvirtd.conf, e.g.
This is true for normal connections using TCP. SSH tunneling works in a different way.

This is not needed for SSH.
On the two instances of libvirt 1.x I have deployed, I just configure and use TLS. Instructions on doing this may be found here:
Please verify that you've got "netcat" installed on the host the daemon is running on (command "nc" in the shell). Also you need to verify that the user account you are using on the machine the daemon is running on has rights to access the libvirt socket.
