Thanks Daniel. After installing xen-devel and rebuilding libvirt, the sample program worked. -Ganesh On Wed, Apr 14, 2010 at 2:48 PM, Daniel P. Berrange <berrange@redhat.com>wrote:
Hi,
I downloaded and built the latest libvirt source code 0.8. I installed
library in a custom directory libvirt-0.8.0-install/ keeping all other configurations default.
After this I tried to execute the example hellolibvirt:
[hellolibvirt]# ./hellolibvirt xen Attempting to connect to hypervisor libvir: Remote error : unable to connect to '/root/ganeshp/libvirt-0.8.0-install/var/run/libvirt/libvirt-sock',

My libvirtd was running from /etc/init.d/libvirtd. Still why is it trying to connect to the newly built libvirtd?
I stopped the /etc/init.d/libvirtd and started my newly built daemon: [hellolibvirt]# /root/ganeshp/libvirt-0.8.0-install/sbin/libvirtd start & 04:47:07.534: warning : qemudStartup:1574 : Unable to create cgroup for driver: No such device or address 04:47:07.540: error : parse_socket:126 : cannot open /sys/devices/system/cpu/cpu1/topology/physical_package_id: No such file or directory 04:47:07.540: warning : qemudCapsInit:1068 : Failed to get host CPU 04:47:07.544: warning : lxcStartup:1835 : Unable to create cgroup for driver: No such device or address
After this I tried running hellolibvirt example again: [hellolibvirt]# ./hellolibvirt xen Attempting to connect to hypervisor 04:48:43.166: error : virLibConnError:450 : no hypervisor driver available for xen:/// libvir: error : no hypervisor driver available for xen:/// libvir: error : no hypervisor driver available for xen:///
This means you have built libvirt without Xen support. It should have told you after you ran 'configure' which drivers were enabled.
