Configure a Host ISO-based Package Repository on a CentOS 7.2 VM

In a recent blog post, I demonstrated how to set up a local RPM repository (repo) in a VMware CentOS 7.2 VM (AKA guest) running under VMware Workstation (AKA the host.) This made the CentOS VM independent of the need for network access w.r.t. RPM package installation. However, the trade off for the ability to install packages without Internet access is the 6 GB plus increase in the size of the VM necessitated for storing all the packages and metadata. Consider the following alternative scenario. You have downloaded the CentOS-7-x86_64-Everything-1511.iso from the CentOS Project or a mirror, used the ISO

Configure a Local ISO-based Package Repository on a CentOS 7.2 VM

Consider the following scenario. You have downloaded the CentOS-7-x86_64-Everything-1511.iso from the CentOS Project or a mirror, used the ISO to create a VM in VMware Workstation, and now want to be able to access a package repository (repo) when you have no Internet access. Assume that a GNOME desktop is available on your CentOS VM and the VM is sized such that you have at least 8 Gb of free disk space. Copy the IS0 to your CentOS VM by whatever method works for you. If you have VMware Tools installed, you can just drag and drop the file using

Nesting RHEL7 KVM on VMware Workstation 12

Recently I wished to build a Red Hat Enterprise Linux 7 (RHEL7) appliance with 2 KVM-virtualized guests. Essentially a type 2 hypervisor (VMM) on top of another type 2 hypervisor. I installed RHEL7 on VMware Workstation 12 and configured it as a Virtualization Server. It was a smooth install without any issues. However I was surprised to find that KVM (Kernel-based Virtual Machine) simply did not work at all and lsmod did not even list the KVM kernel modules. It turns out that you need to do two changes to your RHEL7 guest configuration file in order for KVM support

Using VMware Workstation To Experiment With UEFI

VMware Workstation 9 and later appear to have a robust implementation of UEFI firmware including a full implementation of the UEFI v2.30 Shell. In this post I will show you how to set up a VMware Workstation virtual machine (VM) which allows you to experiment with the UEFI Shell and the various UEFI command line tools. I assume you are familiar with VMware Workstation and the UEFI Shell. In this post I am using VMware Workstation 9. The first step is to create a new typical 64-bit Windows 7 VM using the “I will install the operating system later” option.

Enable VMware Workstation tools in RHEL7

If you install the minimum version of Red Hat Enterprise 7 as a VMware Workstation guest, you will have to overcome a number of obstacles to installing the VMware Tools. Firstly, no ifconfig utility is installed. To install this utility, install the net-tools package. # yum install net-tools Next, check to see if the open-vm-tools package was installed. If not install it from your DVD or ISO. You may have to first create a repo entry similar to the following: [dvd] name=red Hat Enterprise Linix [DVD] baseurl=file:///run/media/<FIXTHIS>/RHEL-7.0 Server.x86_64 enabled=1 gpgcheck=0 and then run: # yum install open-vm-tools I found that
