Context: I own a machine; I trust root and all the accounts. I virtualize untrusted guests using KVM, and don’t want them to escape.
When /dev/kvm has the right permissions, non-root users can run KVM guests. Does this bring any security a… Continue reading What are the security risks of running QEMU/KVM as root?
Stumbled upon a privacy conscious hosting provider that uses LXD vs KVM to manage user VPS instances.
My understanding is KVM is more isolated so using LXD doesn’t make sense from a privacy perspective.
Perhaps I am missing something?
… Continue reading Is LXD virtualization as isolated and secure as KVM virtual machines?
Remote access is great, but if the machine stops booting, ceases to connect to the network, or needs low-level interaction like BIOS settings or boot management, remote access is worthless because it’s only available once the host computer is up and running. The usual solution is to drag a keyboard …read more

The Arduino platform is one of the most versatile microcontroller boards available, coming in a wide variety of shapes and sizes perfect for everything from blinking a few LEDs to robotics to entire home automation systems. One of its more subtle features is the ability to use its serial libraries …read more
I was wondering if it is secure or not to run containers from different customers on the same machine. Basically I was investigating the level of isolation / security provided by Docker alone.
Then I found Google Cloud Run, and I was won… Continue reading Does Google Cloud Run (or AWS Lambda) rely on container isolation or KVM?
I run a lot of vm-guests on a host and manage they with wirt-manager. Whats the best practice to group them for a better overview? Best: independ on the guest names
I figure out a good way is to use the title field, i.E.
… Continue reading What’s the best practice to group vm guests in virt-manager?
[Radishmouse], despite the handle, is not a mouse guy. Give him a keyboard and he will get around just fine in any OS or program. As it is, he’s got a handful of ThinkPads, each running a different OS. He wanted to be able to switch his nice mechanical keyboard …read more
An essential tool of many sysadmins is a portable terminal ready to plug into an ailing rack-mounted server to administer first aid. At their simplest, they are simply a monitor and keyboard on a trolley, but more often they will be a laptop pre-loaded with tools for the purpose. Sysadmins …read more

With KVM guest systems so prevalent now, I was wondering if there is any merit in using LUKS encrypted storage, as the guest will usually be always on, so the information is always accessible unencrypted to the guest, and thu… Continue reading Can information somehow be secured from the host on a KVM guest?
Sometimes you have a whole bunch of computers that you need to work with, and having a keyboard, monitor, and mouse for each one becomes too much to deal with. There are a multitude of solutions to this problem, but [Fmstrat] went the hacker route, and built their own.
The build is a rather unique way of controlling PCs remotely, but it does the job. A Raspberry Pi 3 is pressed into service as the core of the operation. It’s accessible over IP for remote control. Video is captured from the controlled machines through the combination of an HDMI-to-S-Video adapter …read more
