Xen users - Oct 2011 - XCP 1.1.0 - how to use VNC for installing guest domains?

Hello,

Is it required to install an additional VNC server on XCP 1.1.0 dom0 box 
(ip 192.168.1.50)to get access to VNC-windows for installing domU guests?

As I don''t use m$ / XenCenter so I need VNC for installation of new
guests.

The VM is running (s. below) *but* I was not able to open VNC window to 
continue the installation (s. error message further below)

(maybe OpenXenManager could work for you?)


Hope that helps.

Thanks,

No, it''s not necessary. XCP starts vncservers for each running VM
(including domain 0). I''ve attached a script that I use for attaching
vnc clients to VMs. The script assumes that you have root ssh access to
the host.

I''ll upload this script to the wiki page that Todd pointed you to
earlier.

Thank you very much Todd.

I can open now vncviewer window according to wiki pages or a script from 
Mike McClurg.

I have some other issues like troubles with recognizing of network 
interface (I use bonded interfaces in dom0) during trial net-install of 
ubuntu however I should address them separately on the xen-users list.

Thank you very much Mike.

Your script is working perfectly. I have some other issues, however I 
will report them separately to the xen-users list.

E.g. when I try to start the same VM again (after breaking the first try 
to install) I am getting the following error (even it is a net-install 
and there shouldn''t be any disk image due to my understanding):
# ---
[root@xcp-dev01 ~]# xe vm-start uuid=462614f1-5a4d-6fe2-6e74-141c2a9c3721
