Re: [convirt-users] ConVirt 0.8.1 + CentOS 5.1: Exception: Unknown type (null)

[Brecht Sanders]

Hi,
Yesterday I was trying convirt 0.8.1 on win32, trying to connect to xen 
3.0.3-1 on Debian Etch.
I ran into pretty much the same problem: there is no port 8006 being 
listened on by Xen (I checked with netstat -na). Isn't the RPC port 
8005, or is it not using the Xen RPC server?
I tried using port 8005 but I still got connection refused, even though 
netstat showed a connection established to port 8005 for a moment...
Also, there is an option to connect directly with TCP (no SSH). However, 
I didn't find how Xen can be made to bind to all interfaces (not just 
loopback/localhost). Is this possible (or maybe only newer versions ox Xen)?
Regards
Brecht

 Hi
   We have tested the CentOS 5.1 as server platform not
 as a client. 

 You should use 3.0 version of the script if it is
 vanilla CentOS 5.1. 

 But it seems you have installed xen 3.2 is that
 correct ?
  Please pass on the following info 
   -- xm info 
   -- xend-config.sxp file.
   -- netstat -an | grep LISTEN 
   -- check that firewalls are turned off (for testing)


   -- For running ConVirt on 5.1 I think you are
 running in to pygtk problem. See if you can get a
 patch or upgrade.

 Hello,

 I have the following installed:

   - CentOS 5.1 + CentOS Virtualization packages
   - Xen 3.2 CentOS/RHEL RPM from www.xen.org
   - gtk2-2.10.4-19.el5, pygtk2-2.10.1-8.el5 (most up
 to date for the distro)
   - ConVirt 0.8.1

 After installation of ConVirt, I have run the the
 following scripts, per
 the manual:

  

 
 /usr/share/convirt/config-scripts/xen-3.1/configure-xend.sh
   
   /usr/share/convirt/patches/patch_paramiko'
 scripts.

 I am able to start ConVirt OK, but whenever I try to
 do anything, I get
 the following error running locally (as root):

   Exception: Unknown type (null)

 The problem is the same with both the RPM and
 tarball versions.  I am also
 not able to connect to the server from the ConVirt
 0.8.1 client installed
 on my Kubuntu laptop (using the tarball download); I
 get the following
 error when I try to add the server:

   111, 'Connection refused'

 I do not see port 8006 (or anything even mentioning
 'xend') when I do a
 'netstat' command (nor 'netstat -l')

 I am thinking my problem may be one or more of the
 following:

   1.) Running Xen 3.2, which may not be supported
 yet (i.e., the
 configure-xend.sh script for Xen 3.1 does not do
 what it needs to do
 for Xen 3.2)  This may or may not also be the reason
 I cannot connect
 from my laptop
   2.) CentOS 5.1 does not have the proper version of
 GTK libraries that
 ConVirt needs to run

 To eliminate possibility #1 (at least as far as the
 Unknown type
 errors), I am planning to re-install CentOS 5.1 (I
 just did an install
 earlier, so I am not losing any VMs or anything) and
 will use the CentOS
 virtualization packages and will do the api
 adjustment in
 '/etc/convirt.conf' as indicated in the manual.

 A couple of questions, however:

   1.) When I use the CentOS 5.1 Xen packages and
 such, which
 'configure-xend.sh' script do I use?  The one for
 3.1 or 3.0?  I am
 thinking 3.1, since that is what is apparently
 installed with CentOS
 5.1, despite it saying that it's 3.0.3.
2.) Is anyone running ConVirt 5.1 successfully on
 CentOS 5.1?

 In the meantime, any additional advice or info you
 need, feel free to ask
 and I will provide as best I can.

 TIA,

 -Alan M.

[xenman-users] xenman on win32

[Brecht Sanders]

Hi,
I have been looking around for XenMan on the win32 platform and couldn't 
find anything about this.
Have you any knowledge of people running it on win32?

I have attempted to port it to win32 and since it's written in Python I 
thought it shouldn't be that hard to do.
Currently I am able to run XenMan on Windows (see attached screenshot), 
but of course all the paths are quite different since Windows doesn't 
use paths like /etc and /var/log.

The only thing missing however on Windows is the vte library, and I 
wasn't able to find any win32 binaries of libvte so far.
As a result the console button doesn't work.
Does anybody know where to search ports of libraries like vte?

Another thing that keeps popping up us that the line
self._parser.Parse(, 1) # end of data
in pythondir\Lib\xmlrpclib.py causes the exception:
no element found: line 1, column 0
Is there any way to avoid this?

Regards
Brecht Sanders
