Get information about Xen host.

The Xen hypervisor that booted doesn''t match the API installed.

Check your grub.conf

Is this the xenlinux kernel from Xen.org? Why not stick with stock?

If this kernel boots you will see the issue you described.

Can you give the output of rpm -qa "*xen*"

I guess with the appearence of xenlinux you downloaded the tarball and  
did a make install which makes reinstallation of Xen extremely  
difficult.

Next time use the src.rpm from 3.2 to build an rpm package which makes  
reinstalls a lot easier.

It is wholly possible that the Xen-libs package from CentOS was still  
installed when you did the make install and then was upgraded which  
wrote over your 3.3 libs with 3.1 libs.

I hope not but an rpm -qa will show us.

Re: [Xen-users] Unable to open a connection to the Xen hypervisor/daemon 3

Ross, you are right. I did wrongly the installation of Xen 3.3.
On installing the Xen 3.3.0, I forgot that I was on Xen world.
It must be some crashes of both xens, thus, the virt-manager and xm
doesn''t
connect to the hypervisor.
So let me reinstall CentOS without xen kernel on it.
I will be trying to reinstall xen 3.3 again.
Thank you

Best Regards
