Re: [libvirt-users] Is libvirt supported on Citrix Xenserver?

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.

Here you entered root

but here it asks for intel123's, that's unexpected. Did you edit this
one before mailing it, or is there really this mismatch?

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.

The XenAPI driver expects a server name. xenapi:/// _could_ be treated
as xenapi://localhost, but it's not implemented that way.

Running 'make rpm' should build an libvirt-devel RPM package for you.
