I tried compiling the libvirt 0.9.2 with xen api support. Was able to install it successfully. When I tried giving the virsh command, I got an ‘authentication failed’ error as shown below.

# virsh -c xenapi://<my local ip>

Enter username for <mylocalip>: root

Enter intel123's password for <my local ip>:

error: authentication failed: (null)

I also tried connecting to the local machine as below,

virsh -c "xenapi:///"

error: authentication failed: Server name not in URI

error: failed to connect to the hypervisor

What am I missing here?

Also I am trying to install ruby-libvirt on xenserver, which looks like requires libvirt-devel package to be installed. How do I build it from the libvirt 0.9.2 source package.

Thanks,

Naresh

The means that your libvirt version is new enough and contains the
XenAPI driver but that it was disabled on configure time, probably
because the build server didn't have libxenserver installed and
libvirt's configure script automatically disabled the driver because
of a missing dependency.

Then Citrix build libvirt without XenAPI support. As a long term
solution you could report to whom ever is responsible for that repo
and request to enabled XenAPI support in that libvirt package. As a
short term solution you could build libvirt from source yourself and
make sure to get the XenAPI driver enabled.

According to http://libvirt.org/hvsupport.html and the error message
0.8.2 is new enough.
