[OpenSER-Users] Strange OpenXCAP behaviour in virtualized environment

[Schumann Sebastian]

Dear all
 
This week, I tried again to bring up finally the OpenXCAP server. I
tried it first acc. the instruction on OpenXCAP.org on my local virtual
VMWare Server 1.0 (before, I always used virtualized ESX server). It
worked without major issues, meaning I could install lenny, all required
files even via apt-get and the OpenXCAP was running. Surprising for me
though, because it never worked yet.
 
Now, when I take _the same_ virtual disk and export it to VMWare ESX
server, I get the previously discussed errors:
Sep 25 17:01:21 openxcap openxcap[11876]: [-] Log opened.

Sep 25 17:01:21 openxcap openxcap[11876]: [-] Starting Open XCAP 0.9.3

line 67, in etree.XMLSchema.__init__

Sep 25 17:01:27 openxcap openxcap[11876]: [-] etree.XMLSchemaParseError:

How can this be possible? I tried three times with three different
machines. They work in VMware Server but not in ESX server. I don't find
any answer at all neither can I imagine anyhow, how an application error
like this occurs running the program on the very same, identical
virtualized system with just two different virtualization platforms
around.

 

Anybody else has experiences in that, encountered somehow same strange
behaviour with the application or has any other advice? I would really
welcome every hint in somehow a direction to solve this. I didn't plan
to extend my virtual OpenSER testing platform with a local PC, but it
seems I have no other possibility so far...

 

Thanks for your help! A nice weekend to all of you.

 

Best regards

Sebastian
