I think this is a feature. If you launch virt-manager as root (sudo), you are able to connect. Here is an extract from the libvirt site:
========== >8 ============== Legacy: Xen proxy Libvirt continues to support connections to a separately running Xen proxy daemon. This provides a way to allow non-root users to make a safe (read-only) subset of queries to the hypervisor. There is no specific "Xen proxy" URI. However if a Xen URI of any of the ordinary or legacy forms is used (eg. NULL, "", "xen", ...) which fails, and the user is not root, and the Xen proxy socket can be connected to (/tmp/libvirt_proxy_conn), then libvirt will use a proxy connection. You should consider using libvirt remote support in future. ========== 8< ============== Ref: http://libvirt.org/uri.html -- Virt-Manager Error: Unable to open a connection to the Xen hypervisor/daemon. https://bugs.launchpad.net/bugs/220985 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
