drpfeature-test-vbox

Intent
This is the drpfeature-test vbox setup for testing drp-provision.
Success
vbox setup for PXE boot nodes on an isolated network so broadcast messages are easy to monitor.

STATUS: FAIL to boot a VM in Virtual VBOX

Manual Steps - VirtualBox Install

  1. Setup network configuration using drpfeature-test-network
  2. Install VirtualBox on drpfeature-test-macosx
  3. Start VirtualBox
  4. Configure PXE Bare Metal Node bm1
    1. New -> Name: bm1 - Type: Linux - OS: RedHat 64-bit
    2. Memory -> 1024 MB
    3. HD -> 8 GB
    4. CPU -> 2
    5. Network -> Attached to: Bridged Adaptor - Name: en0: Ethernet - Promiscuous Mode: Allow All
    6. System -> Boot Order: Network at TOP
  5. Attempt to start the VM so VirtualBox attempts to create the network connetion
  6. Shutdown bm1 when it fails
  7. Shutdown VirtualBox
  8. Reboot drpfeature-test-macosx (required for some reason for pxe dhcp to work through VirtualBox on drpfeature-test-macosx setup.

  11. CREATE clone image drpe-CLONE-fresh-no-subnet
    1. STOP drp-provision
    2. sudo shutdown now
    3. VirtualBox
      1. Wait till drpe stops
      2. Right-click drpe -> Clone ( name: drpe-CLONE-fresh-no-subnet )
    4. On host (macosx) /Users/msops/VirtualBoxVMs/
      1. Right-click drpe-CLONE-fresh-nosubnet (5.28GB) and Compress (zip down to 4GB)
    5. Wait for compress to finish… this is a good point to save while debugging network configs
  12. Create a subnet via drpcli see drp-install-subnet for help
    1. Start drpe VM and drp-provision
      1. Start drpe virtualbox vm
      2. ssh drpops@192.168.88.3 (I want it running in it’s own term so I can see stdout)
      3. cd drpisolated
      4. sudo ./dr-provision –static-ip=192.168.88.3 –base-root=/home/drpops/drpisolated/drp-data –local-content=”” –default-content=”“

      1. ssh drpops@192.168.88.3
      2. [drpops@drpe drpisolated]$ sudo systemctl stop firewalld
    3. Create a new subnet for iPXE

      1. ssh drpops@192.168.88.3 (I want it running in it’s own term so I can see stdout)

      2. cd drpisolated

      3. vi drpfeature-subnet-config.json

}

      4. ./drpcli subnets create - < drpfeature-subnet-config.json

      5. Create subnet via drpcli done

    4. Verify subnet drpfeature-test-subnet
      1. ./drpcli subnets list
      2. Should return drpfeature-subnet-config.json string

    5. Create subnet Verify check complete

  13. Verify drpfeature-test-subnet
    1. In RackN-Portal you should see green check on Subnets
    2. Browse to Subnets you should see the subnet you configured above.
  14. Create a machine to iPXE boot see drp-install-machine for help

    1. Set BootEnvs:

      [drpops@drpe drpisolated]$ ./drpcli prefs set unknownBootEnv discovery defaultBootEnv sledgehammer defaultStage discover

    2. Verify BootEnvs browse to Info & Preferences and see above in System Preferences

    3. Setup PXE Boot on a vm (see above bm1)
      1. Start bm1
      2. bm1 should boot into discover then sledgehammer
      3. Verify bm1 discovery browse Machines
      4. Login to bm1 console: root - rebar1 to verify sledgehammer is on bm1
      5. xxx-tbd-xxx

    4. Obtain you machine ID:

      [drpops@drpe drpisolated]$ ./drpcli machines list | jq '.[].Uuid'

    5. Set the BootEnv to centos-7-install replace <UUID> with your machines ID from the above command:

      [drpops@drpe drpisolated]$ ./drpcli machines bootenv "4678729e-5147-43f6-a569-93b7668b8a40" centos-7-install

    6. Reboot bm1 - it should now kick off a BootEnv install as you specified above.

    7. Verify bm1 access:

      TODO - Put the bm1 access std out from above
  15. Cleanup

    1. Install jq:

      [drpops@drpe drpisolated]$ sudo yum install jq

    2. Turn off firewalld:

      [drpops@drpe drpisolated]$ sudo systemctl stop firewalld

    3. DISABLE firewalld:

      [drpops@drpe drpisolated]$ sudo systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[drpops@drpe drpisolated]$
  16. CREATE clone image drpe-CLONE-drpfeature-test-network
    1. STOP drp-provision
    2. sudo shutdown now
    3. VirtualBox
      1. Wait till drpe stops
      2. Right-click drpe -> Clone ( name: drpe-CLONE-drpfeature-test-network )
    4. On host (macosx) /Users/msops/VirtualBoxVMs/
      1. Right-click drpe-CLONE-drpfeature-test-network (5.28GB) and Compress (zip down to 4GB)
    5. Wait for compress to finish… this is a good point to save while debugging network configs

  17. I THINK THIS IS Done… nope ks still stuck

Setup for testing drp endpoint

drpfeature-test setup uses the drpfeature-test-network and drpfeature-test-vbox running on a drpfeature-test-macosx with drp-provision running on the drpfeature-test-drpe endpoint for pxe boot of Proliant Blade servers in drpfeature-test-hpeC7000 configuration which then are assessable via drpfeature-test-drpe-ansible and can use drpfeature-test-drpe-ansible-blender to install a blender render grid worker node.
