Addendum to Dual Display KVM Post

Three years ago I wrote a post (along with a Youtube video) about how to set up a KVM VM with Dual Monitors (or even triple monitors). Since then there’s been a bit of a change. I loaded up remote viewer and, for some reason, I couldn’t add more monitors to my Linux KVM VM. …

Exploring Rockstor

I’ve been looking at NAS implementations for a long time. I looked at FreeNAS for a while then OpenMediaVault. But what I really wanted was to be able to take advantage of btrfs and its great RAID abilities – especially its ability to dynamically expand. So I was happy when I discovered Rockstor on Reddit. …

Setting up a Team Fortress 2 Server on CentOS 7

I used to have a Team Fortress 2 server on CentOS 6 with Virtual Box. Now that I’m using KVM/QEMU/Libvirt, I wanted to set up a new one. Also, Valve somewhat changed how they worked a few years ago and I wanted a clean slate. I started with a VM with 40GB. It’s not supposed …

Host to Guest Comms on KVM

So, the current solution for bridging with KVM/QEMU/Libvirt involves macvtap. This allows your VM to be seen by computers on the network which is key if you want to, say, run a server or DNS on a VM. However, there’s a catch – the host can’t reach the VM. Sometimes this doesn’t matter and sometimes …

Home Server Project Update 2: Goodbye Arch Linux

As I documented before, I’ve had problems with Pogoplug and Arch Linux running my servers. Recently I’ve been having problems logging in via SSH on my updated Fedora computers. From what I can tell from a little research, it seems the old way of connecting had a flaw so updated SSH doesn’t want talk to …

In case you’re having issues creating a new VM in Virt-manager

Tried to use virt-manager again (more about that in a future post), but kept getting the error: qemu-system-x86_64: error while loading shared libraries: libGL.so.1: failed to map segment from shared object: Permission denied Well, turns out this blog post had the answer for me: sudo setsebool -P virt_use_execmem=on That blog appears to be a great …

Oracle’s Virtualbox vs Red Hat’s Virtual Machine Manager

I’ve been using Virtualbox for a long time to run virtual machines when I want to check out other distros before I install them on one of my computers or to review them.  It’s MOSTLY open source, although some of the key parts like USB 2.0 are free to use, but not open source.  So …
