Creation and OS Installation of the VirtualMachine that will work as the Undercloud server (OpenStack Pike TripleO)

Creation and OS Installation of the VirtualMachine that will work as the Undercloud server.

you can use command line of virsh or also the virt-manager GUI to create a Virtual Machine. 

I have already the CentOS7 Minimal Install media stored and known for the libvirt at /var/lib/libvirt/images on the KVM Host

For the undercloud, The VM created has 8 CPUs, 46GB RAM and 40 GB IDE HDD.

If you need the CLI here is the same.

virt-install --name pike1.sujitnet11.net --noautoconsole --virt-type qemu --memory 47102 --arch x86_64 --vcpus 8 --cpu host --location /var/lib/libvirt/images/CentOS-7-x86_64-Minimal-1611.iso --disk size=40,path=/var/lib/libvirt/images/pike1.sujitnet11.net,format=qcow2 --network network=nat

This installs the Virtual Machine with 46GB RAM, 8 CPUs, Mapping the CPU Host configuration to the VirtualMachine, with QEMU as the virtualization type. This uses the media (--location) /var/lib/libvirt/images/CentOS-7-x86_64-Minimal-1611.iso as the installation source. A Virtual disk of format qcow2, size 40GB gets created by this at the location /var/lib/libvirt/images/pike1.sujitnet11.net. Attachment of the Virtual Machine to the 'nat' network is done during this. The '--noautoconsole' says not to automatically connect to the console of the VirtualMachine after creation

root@win2k12r2 images]# virt-install  --name pike1.sujitnet11.net --noautoconsole --virt-type qemu --memory 47102 --arch x86_64 --vcpus 8 --cpu host --location /var/lib/libvirt/images/CentOS-7-x86_64-Minimal-1611.iso --disk size=40,path=/var/lib/libvirt/images/pike1.sujitnet11.net,format=qcow2 --network network=nat

Domain installation still in progress. You can reconnect to

the console to complete the installation process.

[root@win2k12r2 images]#

Connect to the console for the installation part , I used the virt-manager to do so.

The Virtual Machinre reboots after the installation.
