I read something interesting the other day. Running multiple VMs, on the same computer; the catch is that they are all running on the same desktop (not headless) sharing one display. The term is “kvm localized virtual desktops”.

The place I read this was the UnRaid blog, talking about KVM integration into the UnRaid 6 system (SOURCE).

Since OpenSuSE has tools and support for kvm, I shall try this.

It would be interesting to run linux and windows and not have to dual boot, and have access to the same GPU from both OSs.

Recently came across one of my linux VM machines that ran out of disk space. But where did all the space go? What ate it up?

du -h <dir> | grep ‘[0-9\.]\+G’

This will list a sorted view of the foles/folders from largest to smallest.

I like the last poster’s answer: (need to install pv)

pv -tpreb input_file | dd of=output_file.

Installing the Brother HL-2070N printer in linux (more specifically my openSUSE installations) has been an intimidating task. Until now.

I found a simple guide here. Straight to the point, 2 min install, and bam, everything is working. Thanks Andrew!

Booting into runlevel 3 to install nvidia drivers:

1. Press the E key for theedit screen.
2. Find: /boot/vmlinuz
3. Press the End key to move cursor to the end of the line
4. Add “space” and 3 to the end of the line.
5. F10 to reboot to runlevel 3

I know this will come in handy again:

Adding the option “discard” to the fstab line for option settings is the trick. This only works with ext4 and xfs file systems
