Hey Daniel, Thanks for the reply. The strange thing is, libvirt isn't even attempting to establish a connection with the remote server. I've performed tcpdumps to verify this; no traffic is exchanged between the two hosts when executing the virsh command. If I switch back to a version of libvirt below 0.5.0 such as 0.4.6, it works like a charm. Is there anything else I could try? Hany On Mon, Jun 8, 2009 at 7:04 AM, Daniel P.

Hi, I'm currently running a few servers with CentOS 5.3 (i386) with the stock Xen version:
# rpm -q kernel-xen xen libvirt kernel-xen-2.6.18-92.1.22.el5 kernel-xen-2.6.18-128.1.6.el5 xen-3.0.3-80.el5_3.2 libvirt-0.6.3-1
libvirt was compiled from the src RPM from libvirt.org to run on i386 architecture without issue. I'm having a problem when trying to connect to remote Xen installations using versions of libvirt starting from 0.5.0 and above. When issuing virsh commands to query the local instance, it works without issue, but any remote sources gives 'error: failed to connect to

It looks very much like the remote driver is failing to connect to the remote libvirtd daemon. Please verify that libvirtd on the remote host was started with the --listen flag, and that you have configured x509 certificates and have not disabled the 'listen_tls' config param in /etc/libvirt/libvirtd.conf
