This repo holds details for the demo of the current sprint work in kubevirt

scope of the demo

• deploy downstream openshift 3.9 on 3 masters + 3 nodes with metrics and cns
• deploy latest kubevirt
• show v2v apb
• import windows vm disk with v2v apb
• show vm entities in the console, start vm from console
• launch a windows vm using windows vm template
• access windows vm using exposed rdp fron the outside
• deploy an sqlserver apb
• switch the sqlserver of windows to this external one

current issues

• need to find the best HA name for master config... defaulting to first node is wrong
• same template fails to be deployed through template service broker. should leave in default project if old templating system will be used
• seeding script to additional sqlserver is missing
• need to find out proper sqlserver connection string for remote access
• load balancer ips can't be reached through openvpn
• cloning disabled

infra used

• 3 BM physical machines with two additional SSD disks ( for docker and glusterfs)
• openshift-ansible-roles-3.9.14-1.git.3.c62bc34.el7.noarch

requisites

• kernel recent enough (3.10.0-693.21.1.el7.x86_64) as it needs to be able to modprobe target_core_user module

deployment

basic openshift installation

• nodes provisioned with rhel7.4 and subscribed to

  • rhel-7-server-rpms
  • rhel-7-server-extras-rpms
  • rhel-7-server-ose-3.9-rpms
  • rhel-7-fast-datapath-rpms
  • rhel-7-server-ansible-2.4-rpms

• we deploy openshift with this inventory file and with the following commands on first master we also use the following playbook post.yml to disable selinux and install virtctl on all the nodes

yum -y install openshift-ansible screen
ansible-playbook -i /root/hosts /usr/share/ansible/openshift-ansible/playbooks/prerequisites.yml
ansible-playbook -i /root/hosts /usr/share/ansible/openshift-ansible/playbooks/deploy_cluster.yml

post install

we disable selinux and install virtctl on all the nodes with this template

ansible-playbook -i /root/hosts /root/post.yml

demo install

we install kubevirt and sample elements with this template making use of the demo role

ansible-playbook -i /root/hosts /root/deploy.yml

Workflow

• deploy a windows vm using template from the openshift UI. this will:
  • create the offline vm (stopped) based on the existing windows pvc
  • create a service for rdp (using node port, as load balancer is failing because of vpn routing issues)
  • create a service and a route for http
• access windows vm rdp using the provided link
• TODO: seed sqlserver linux database
• TODO: switch sql server DB in the windows vm

Additional tricks

• downloading a big image from a google drive with command line

# get image at https://github.com/prasmussen/gdrive#downloads
sudo cp gdrive-linux-x64 /usr/bin/gdrive
sudo chmod a+x /usr/bin/gdrive
gdrive download 1hG9otdB7Vs2J1nqwyUPpdVKP3QdvAqoC
qemu-img convert -O raw SummitVM.vdi SummitVM.img

Lessons learnt

• needs links for everything that needs testing!
