Please use screen -r command for attaching existing screen when connection has been terminated. Sometimes it still grubbed the screen by a zombie connection.

It should kill old pts/n then attaching to screen by command screen -r after reconnect with below procedures.

$ ssh -i ~/.ssh/id_rsa stack@192.168.100.30
[stack@rdo ~]$ ps aux|grep pts|grep sshd
stack     9246  0.0  0.0 131068  2056 ?        S    00:01   0:00 sshd: stack@pts/1
stack     9511  0.0  0.0 131068  2048 ?        S    00:29   0:00 sshd: stack@pts/3
stack     9544  0.0  0.0 112640   960 pts/3    S+   00:30   0:00 grep --color=auto sshd
[stack@rdo ~]$ kill 9246
[stack@rdo ~]$ screen -r

Virtual Machines installation

Set up 3 VMs in virtual environments. Install the instack-undercloud for VM creation.

[stack@rdo ~]$ sudo yum install -y http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
[stack@rdo ~]$ sudo yum install -y https://rdoproject.org/repos/openstack-kilo/rdo-release-kilo.rpm
[stack@rdo ~]$ sudo curl -o /etc/yum.repos.d/rdo-management-trunk.repo http://trunk-mgt.rdoproject.org/centos-kilo/current-passed-ci/delorean-rdo-management.repo
[stack@rdo ~]$ sudo yum install -y instack-undercloud

Configure Virtual Environments

Create 3 VMs for running undercloud.

Thease will be created and ran by below commands. 2 baremetal VMs will be launched at Overcloud deploying.

Please use command virsh start instack for VM starting when you shut down host machine.

[stack@rdo ~]$ instack-virt-setup
[stack@rdo ~]$ sudo virsh list --all
 Id    Name                           State
----------------------------------------------------
 2     instack                        running
 -     baremetalbrbm_0                shut off
 -     baremetalbrbm_1                shut off

Each VM power management settings

IPMI power management can't use because each VM is not a baremetal machine. Therefore use PXE+SSH instead of IPMI for using virtual environment with OpenStack like baremetal. It should can ssh to the management address 192.168.122.1.

Created default instackenv.json written for root user. It should be changed to stack user. Please check ssh to 192.168.122.1 as stack user with public key for power management.

[stack@rdo ~]$ ssh-copy-id -i ~/.ssh/id_rsa_virt_power.pub stack@192.168.122.1
[stack@rdo ~]$ ssh -i ~/.ssh/id_rsa_virt_power stack@192.168.122.1
[stack@rdo ~]$ logout

Install Undercloud to instack

VMs has been created. Create Install Undercloud to instack. ssh to instack. IP addresses can be retrieved by below command.

[stack@rdo ~]$ cat /var/lib/libvirt/dnsmasq/default.leases | grep $(tripleo get-vm-mac instack) | awk "{print $3;}"
 192.168.122.221

Chang stack user and run screen after ssh.

[stack@rdo ~]$ ssh root@192.168.122.221
[root@instack ~]# su - stack
[stack@instack ~]$ sudo yum -y install screen
[stack@instack ~]$ screen
