Re: [Xen-API] Question about VM.create

[Fabien Hermenier <fabien.hermenier@xxxxxx>]

I just re-configure the xm client to use the xen-API to create my  
virtual machine (by modifying xm-config.xml).
It appears that I can not create a virtual machine anymore using the  
same xm create -f ... command:
THe xm client hangs up when it uses the method call  
"network.get_all()" that return an empty array.
My network configuration is based on the "network-route" script.

I don't know if this situation is a possible explanation for my  
problem. But just in case, I would like to check.

Fabien
