Hi,
I was finally able to connect to the xenapi hypervisor using virsh of
libvirt 0.9.2. However, once I connect to virsh and give a 'quit'
command I get "* glibc detected *** virsh: double free or corruption
(fasttop):". Please find below the actual memory dump.
Note: I have disabled the SSL certificate verification in xenapi_driver.c
by setting curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0) &
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0).
[root@sharmila libvirt-0.9.2]# virsh -c "xenapi://localhost"
Enter username for localhost: root
Enter root's password for localhost:

connected to this domain (frontend (domid=0 | kind=vbd | devid=51712); backend

Any pointers on the above 2 issues would be of great help.
Thanks in Advance!

Citrix Xenserver?Hi Matthias,
>
Sorry for the confusion.It was an edited one & hence thetypo. 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. Somehowfigured 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 debugthis 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 canuse the source
package and build & install the library without using'make rpm' ?
Thanks for all the help.
