    Been playing with the Sispeed NanoKVM ($40 PiKVM alternative)

    Pretty nice piece of gear, little 1.5in cube basically to give you IP/web KVM access to any PC that you plug it into. I used to spend a lot of time on the road, so I have a good selection of server boards at home already, but didn't have a reliable way to turn it on my linux desktop or...

    Problems with KVM/QEMU passthrough DVD writer

    I've recently changed my server to run as a VM using KVM/QEMU via virt-manager. All has generally gone well, but I now want to make use of the machine's DVD writer from the VM. I've tried passing it through in the same way as I've passed through hard disks (but selecting CDROM and SCSI). That...

    SOLVED (partially) Can't vKVM on Gigabyte Server board

    I'm running a Gigabyte GA-6LISL mITX server board with TrueNAS Core and I am banging my head up against the wall trying to vKVM in. When I attempt to launch the Java KVM client from the web console I get a generic "Connection Failed" error. After doing some research I figured I would give...

    Ideas for using LVM+BTRFS clone and keeping up to date?

    So this is fun, I just woke up to a clone job of my laptop being finished, it was kind of an experiment. It runs OpenSUSE, so it's got a BTRFS root and snapshots triggered by package manager. I wanted to back it up so I could have a copy of the machine to run elsewhere, here's how I did it...

    Did anyone here ditch vSphere for Proxmox, other?

    Hey, I've got vSphere 7 and keep wondering at least once a year if I should ditch vSphere for something open source. I'm thinking KVM-based, but have my eye on the Illumos/FreeBSD bhyve projects, too - although what I've tried of them has been really rough around the edges. Also open to Xen...

    My humble 10Watt server put AWS EB2 to shame!

    Headlines are supposed to be dramatic and only half-truth, right :p After some talk on other threads about power-consumption, AMD, Intel and servers, I thought I'll get some real power numbers on the on-prem servers I usually setup at my customers. Some questioned the power numbers I've been...

    Alpine Linux as OS-base for hypervisor

    Hi everyone, So obviously Alpine is getting a lot of attention lately since Docker is popular, but it also has a plethora of packages commonly available in larger-footprint distros - namely KVM, libvirt and ZFS. It runs easily from RAM since it's so small, and is also unencumbered by systemd...
