below needs some future cleanup & automation

  • /share/apps/genapp/app/output/html5
    • mkdir (this may happen automatically)
      • results
      • deleted
  • /share/apps/genapp/app
    • symlinks
      • ajax
      • util
      • docs
      • results
      • deleted
    • chown -R apache:apache .
    • chmod -R g+rw .
      ln -s output/html5/ajax ajax
      ln -s output/html5/util util
      ln -s output/html5/results results
      ln -s output/html5/deleted deleted
      # docs for sassie
      ln -s /var/www/htdocs/docs docs  
      chown -R apache:apache .
      chmod -R g+rw .
      

isn't useful

  • centos6.6 uses qemu-0.12x and is not compatible with even reasonably modern versions of qemu (e.g. qemu-0.15.1!)
    • so forget this:
      • KVM install notes
      • modified by:
        • semanage fcontext -a -t virt_image_t "/home/kvm(/.*)?"; restorecon -R /home/kvm
      • virt notes
         Create a guest from an existing disk image 'mydisk.img' using defaults for the rest of the options.
                 # virt-install --name demo --ram 512 --disk /home/user/VMs/mydisk.img --import
           note: this example might not work with selinux enforcement unless the user directory has correct authority, I went to /home/kvm
        
         So for us:
           # virt-install --name sassie-mobile --ram 8192 --vcpus 2 --bridge virbr0 --nographics --disk /home/kvm/sassie-web_mobileentropy.img --import
        
      • virt-manager
        • sometimes needs # dbus-uuidgen > /var/lib/dbus/machine-id
