Creating manageable virtual machines: Implementing

V/ IMPLEMENTING 1. Hardware requirements Virtualization Technology (VT) support in processor is required. You can check to see if your processor supports VT by running this command: egrep ‘^flags.*(vmx|svm)’ /proc/cpuinfo If you get any output then you have VT technology. In addition, you need to go into the BIOS and make sure it is enabled. […]

Creating manageable virtual machines: Making a boot disk image

IV/ MAKING A BOOT DISK IMAGE Making a boot disk image is similar to the steps in Bring Omarine to a cloud. However, there are some adjustments: Install additionally the dhcp-4.3.5-1.x86_64 package. When running the new operating system, in addition to the sub-steps in there, configure it as a client. For virtual machines using dynamic […]

Creating manageable virtual machines: Configuring DHCP server

III/ CONFIGURING DHCP SERVER Once you have a successful name server, everything will be easy. We modify the dhcpd.conf configuration file, deleting unused lines in the new schema: sudo sed -e ‘/^on commit/,$d’ -e ‘/authoritative\|netbios/d’ \ -i /etc/dhcp/dhcpd.conf Next, select Dynamic DNS Update style: sudo sed ‘/ddns-update-style/s,none,standard,’ -i /etc/dhcp/dhcpd.conf Modify the domain name: sudo sed […]

Creating manageable virtual machines: Setting up name server

II/ SETTING UP NAME SERVER We use the omarine.org domain to illustrate. The server has IP address of 192.168.0.1, named omarine.omarine.org. You replace them with your own values when applied in practice. 1. Creating a key to update resource records There are several ways to create a secure DNS key, we use the following command: […]

Creating manageable virtual machines: General Network Setup

We have brought Omarine to a cloud and run it in a guest VM. Now we create a full virtual machine system that includes a host machine and guest virtual machines. I/ GENERAL NETWORK SETUP There are two solutions to setup network interfaces on a server running Omarine: Using NetworkManager and static IP services; use […]
