I have 2 headless KVM servers (Debian based). I use an Ubuntu desktop to manage the guests using virt-manager.
From the workstation I can use virt-manager to connect to the hosts by hostname (see attached screen shot virt-manager_lan.png)
I cannot use this instance of virt-manager to create new guests because virt-manager is not aware of the DRBD resource I use as a disk. I must connect directly to the host. Because my hosts are headless (no GIU) I use ssh with the -X option to launch virt-manager directly on the host and the xsession is redirected to my workstation, I can then manually enter the path to the DRBD resource (/dev/drbd/by-res/resource).
This works fine - as long as I can get the connection to virt-manager to work. Currently it works on one host (ssh-X_srv-01.png, virt-manager_localhost-srv-01.png) but not on the other (ssh-X_srv-02.png, virt-manager_localhost-srv-02.png).
I found in /var/log/libvirt/libvirtd.log on kvm-srv-02 the following appears when attempting to connect to 'localhost':
2014-02-05 17:58:52.217+0000: 3143: error : virNetServerProgramDispatchCall:384 : unknown procedure: 293

however attempting to connect to the hostname from my workstation does connect and no nessages in /var/log/libvirt/libvirtd.log

Is there anything more that I can provide that might help determine why I cannot connect from localhost but can over the network?
Thanks in advance.
