Failed to run a clickos on Xen. #4

Hi,

I am trying to build and run ClickOS from the source code.
I have successfully compiled and built the image of ClickOS, clickos_x86_64/clickos_x86_64.gz.
However, when I was trying to run the ClickOS as a DomU VM, I got errors.

System environment:

  1. Use OS X as a host.
  2. Install VMware Fusion
  3. Install Debian 7.8.0-64bits as a guest OS inside VMware.
  4. Compile and build Xen-4.4.1 from source code inside Debian.
  5. Use Debian as Dom0.

I use the following command to run ClickOS from Dom0:

  1. cd /path/to/clickos/
  2. xl create minios/config.xen

The error messages:

libxl: error: libxl.c:4594:libxl_set_vcpuaffinity: setting vcpu affinity: Invalid argument
libxl: warning: libxl.c:4608:libxl_set_vcpuaffinity_all: failed to set affinity for 0

Hi

You have to problems:

  • The configuration file says cpus = '2' and you only have 2 cores. You should either remove the declaration or use another core (e.g cpus = '1')
  • The bridge xenbr0 doesn't exist on your system. Create it or change to an existing bridge.

Best regards
Filipe

Thank you so much for your comment, Filipe.
I have made ClickOS run on Xen virtual machine.
