I would like to understand what may be needed/useful for the system NIC.
My plan is to use an Asus mb, Sabertooth or Crosshair. They both have a single on-board Ethernet port. I am wondering about the possibility/need to have a 2-port plug-in NIC. A scenario is to have a domU Windows or Linux SVN/Apache/PostgreSQL VM and interact with it through another domU Windows or Linus VM. I also may want to remote in from the Internet or a Windows remote desktop through a domU Windows VM.
BTW, I am reading "Running Xen: A Hands-on Guide to the Art of Virtualization". In chapter 2, p. 34, it addresses starting a new Debian-based guest creation and it shows the resultant listing. The narrative states "The xmllib warning messages can be safely ignored in this case". The listing shows:
The xmllib module is obsolete. Use xml.sax instead.
warnings.warn("The xmllib module is obsolete.
It doesn't state what the case is and I am new enough not to understand from the context. Why would I not need to be concerned about the warning? Additionally, being new to Linux, I would like to understand how to chase down warnings, errors, etc. While I can move forward just through neglect, I old like to take a knowledgable step.
Thanks,
ray
