Seems fine, "-1" would let the VM itself find out which port it would use. in virsh, dumpxml could used to see the real port that vm have used, different from the definition xml with "-1", so I think in future some logic could be added if user want to see which port an active domain with "-1" port defintiion have used.

# HG changeset patch # User Eduardo Lima (Etrunko)<eblima@br.ibm.com> # Date 1317234028 10800 # Node ID 2313e472149a557143228949878f946278d0dd3a # Parent adc78792781448aca7a1356bd253cbdd689839cb device_parsing: Use default values for vnc graphics device
This patch fixes the behavior where libvirt-cim loses the graphics device description after a call to ModifyResourceSettings method. Actually it has nothing to do with the fact that the domain is running or not. What happens is that if somehow we can't read either 'listen' or 'port' attributes, the function will fail and return immediately, skipping the device inclusion.
The default values are based on the ones found in the default_graphics_device function in src/Virt_VirtualSystemManagementService.c.
