Hi,
Is libvirt supported on Citrix Xenserver. I have been searching for the same
with little/no luck.
If supported, can you point to some links/documents which can help me try
out the same.
Thanks,

libvirt can use XenAPI via libxenserver [1]. That should allow you to
use libvirt with a Citrix XenServer. You can use virsh like this
assuming you have a libxenserver enabled libvirt:
virsh -c xenapi://my-xen-server
But it's true, there is no documentation about this on the libvirt website yet.

Hi Maththias,
Thanks a lot for your response!.
Is there a specific version of libvirt from which xenserver support is
added? I am getting the below error
"error: invalid argument in libvirt was built without the 'xenapi'
driver"
I have installed libvirt from citrix yum repo.
I am using Xenserver 5.5 with libvirt 0.8.2 and it does not seem to be
working.
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.
I have installed libvirt from citrix yum repo.
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.
I am using Xenserver 5.5 with libvirt 0.8.2 and it does not seem to
be
working.
According to http://libvirt.org/hvsupport.html and the error message
0.8.2 is new enough.

Hi Maththias,
Thanks for the help. I finally was able to compile/install libvirt on
xenserver.
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

Hi Maththias,
Thanks for the help. I finally was able to compile/install libvirt on
xenserver.

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
Here you entered root
Enter intel123's password for <my local ip>:
but here it asks for intel123's, that's unexpected. Did you edit this
one before mailing it, or is there really this mismatch?
error: authentication failed: (null)
Outputting (null) here is actually a bug. The only way this can happen
is when the login attempt fails but the XenServer doesn't provide an
error message. Maybe have a look at the XenServer logs to see if it
says something about a failed login attempt.
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
The XenAPI driver expects a server name. xenapi:/// _could_ be treated
as xenapi://localhost, but it's not implemented that way.
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.
Running 'make rpm' should build an libvirt-devel RPM package for you.

Hi Matthias,
Sorry for the confusion.It was an edited one & hence the typo. Below is the
actual output:
# virsh -c xenapi://<myip>
Enter username for <myip>: root
Enter root's password for <myip>:
error: authentication failed: (null)
I was not able to get anything in the Xen logs. Somehow figured out to print
the Xen error using the patch given at the link http://osdir.com/ml/libvir-
list/2011-06/msg00298.html. It prints "TRANSPORT_FAULT". Any pointers to
this
error would be much appreciated. Iam also trying to debug this issue.
As per your suggestion,
I had used make rpm. But it requires xen-devel pacakge, which I was
not able to get for Xen 3.4.2. Is there any way where I can use the source
package and build & install the library without using 'make rpm' ?
Thanks for all the help.

Naresh

Hi Matthias,
Sorry for the confusion.It was an edited one & hence the typo. Below is the
actual output:
# virsh -c xenapi://<myip>
Enter username for <myip>: root
Enter root's password for <myip>:
error: authentication failed: (null)
I was not able to get anything in the Xen logs. Somehow figured out to print
the Xen error using the patch given at the link http://osdir.com/ml/libvir-
list/2011-06/msg00298.html. It prints "TRANSPORT_FAULT". Any pointers to
this
error would be much appreciated. Iam also trying to debug this issue.
The mentioned patch is part of libvirt 0.9.3, but it has a problem. It
altered the call to xenapiSessionErrorHandler in xenapiOpen in a way
that breaks error reporting. libxenserver returns a list of strings
that represents the complete error message. xenapiSessionErrorHandler
with last parameter set to NULL, composes all parts of the error
message into a single string. But the mentioned patch only takes the
first part, in your case "TRANSPORT_FAULT". The second part of that
error message is an numeric error code that might help to understand
the problem.
I just posed a patch to be applied on top of current git to fix this
https://www.redhat.com/archives/libvir-list/2011-July/msg01496.html
I attached a version of this patch that should apply to libvirt 0.9.3.
I'd be glad if you could test it, as I don't have a XenAPI setup at
hand. With that patch applied to libvirt 0.9.3 (or libvirt 0.9.2 + the
patch you mentioned before) you should get 'TRANSPORT_FAULT :
<error_code>' as error message and the number could help to figure out
what the actual problem is.
As per your suggestion,
I had used make rpm. But it requires xen-devel pacakge, which I was
not able to get for Xen 3.4.2. Is there any way where I can use the source
package and build & install the library without using 'make rpm' ?
You can just do the normal ./configure, make and make install dance as
libvirt is autotools based.
Thanks for all the help.
