![]() ![]() In each case, I started with a VM in the form of a. I made separate efforts for Windows XP, 7, and 10. ![]() It seemed I might need to do further tinkering to get the best full-screen resolution: the canned options were all too large or too small for my laptop’s screen, and scaling to enlarge those that were too small made things fuzzier than they were without scaling.Īfter achieving success running Linux Mint MATE as a guest in KVM, I turned to the problem of developing successful Windows guest systems. The other wrinkle involved screen resolution. I wasn’t sure I would need that, nor was I sure whether its performance could be dramatically enhanced, but it was interesting. First, I found that it was possible to run software (e.g., Firefox) in KVM on an Ubuntu live CD running on a USB thumb drive. While exploring those Linux options, I encountered two wrinkles that might deserve further attention later. Later, I wondered (but did not test) whether I could have used the. ![]() qcow2 format using a script that combined the two commands recommended by multiple sources, involving a conversion from. I originally chose Linux Mint Cinnamon for this purpose, but eventually found that it produced a “Software Warning Mode” error message that did not appear in a Linux Mint MATE guest. I started with a Linux guest, downloaded in VirtualBox (.vdi) format from. I tried using several different guest operating systems (OSs) on this LMX host. Then I proceeded to use this LMX system as a base for various kinds of virtual machines (VMs), choosing KVM as hypervisor due to its reputedly superior performance, and sometimes using Virtual Machine Manager (VMM) as KVM’s graphical user interface (GUI) in lieu of the command line. Eventually, I concluded that it was better to have my drives configured as GPT rather than MBR, to boot with the system in UEFI mode (with secure boot disabled) rather than BIOS, and to use a single encrypted LVM partition rather than the traditional list of (e.g., boot, root, home, swap) partitions.Īfter installation, I made relatively few adjustments. After considering various possibilities, I stuck with my previous preference for Linux Mint Xfce (LMX) as my host system.Īs reported here, I made some mistakes in installing LMX. This post began with a search for a Linux distribution that would serve as a good basis for a system primarily focused on running VMs, especially Windows 7. Experimenting on an Ubuntu Live USB Drive Detour: First Try: The “Something Else” Option So if I say something like, I tried running this command, without further elaboration, that probably means I typed those words on the Terminal command line. Note also that commands here are printed in italics. ![]() I expected to be accessing those NTFS containers as shared folders from within my VMs. As detailed in a different post, I had created VeraCrypt encrypted containers, formatted as NTFS, filling ext4 partitions on my laptop‘s hard disk drive. Note, too, that I was focused on setting up only a basic Linux host system, because I expected to use Windows VMs for most of my actual work. In addition, note that previous posts in this blog offer more detailed explanations of many items, ideas, terms, and conventions used in this one. It is not intended as a cookbook, to be followed step by step. First, in characterizing this as a “first cut,” I mean to emphasize that it includes instances of my own errors and confusion. There are a few things to note about this post. I also found that CentOS suffered from a lack of support, being partly restricted from the Red Hat literature available only to paying customers and simultaneously segregated from the relatively substantial literature generated by and for users of Debian-family Linux distributions. I found, unfortunately, that CentOS introduced complexities predictably oriented toward the needs of corporate server administrators rather than end users. To that end, I tried Linux Mint Cinnamon and then CentOS. As discussed in earlier posts, I had decided to find, install, and configure an operating system (OS) that would serve as a stable long-term host system for running virtual machines (VMs) in KVM. ![]()
