A few weeks ago I had a post on a process I ve put together to move an Ubuntu installation from a virtual machine to a physical notebook. The core of the procedure was to use Clonezilla in the VM to create a backup and then to restore the backup on an empty SSD in a Continue reading Moving from Virtual to Physical is even Easier DD does the Magic
In the previous posts on the topic I ve been looking at how disk images can be downloaded and uploaded to virtual machines in data centers. Depending on the data center owner, this is more or less straight forward. There is one tricky thing however, independently of the data center provider: What if the VM in Continue reading Shrinking the System Partition and a VM Disk Image
In a previous post I ve had a look at how I could download the disk image of a VM running on a Netcup server and run it in a VM on my own bare metal server at home. The procedure is straight forward, because Netcup offers an option for this in the admin interface. A Continue reading VM Liberation Downloading the Disk of a Running VM from Hetzner
Once upon a time eth0 was eth0 on Linux. But then, some people thought it would be a good idea to rename the network interface on boot to correspond and map the name to the physical interface. In many cases, that is a good idea, but for virtual machines that suddenly and miraculously change the Continue reading Netplan and How To Get eth0 Back!
In part 1 of this series I ve used this blog as a quick test of Netcup s tiny and cheap VM offer that I have come quite fond of in the meantime. So it was time to move a real application to it I was running on a more expensive VM in a different data center: Continue reading Netcup Part 3: Smooth Packet Jitter
In the previous post I described my first experiences with Netcup and that the server management interface held a pleasant surprise I would describe in a follow up post. So here it is: Uploading and downloading disk images! Unlike VMs I have used at different data center providers in the past, Netcup seems to use Continue reading Netcup Part 2: Up/Downloading Disk Images
Over the years, I ve moved more and more services I was hosting on Hetzner to other infrastructure providers due to pricing and interconnection issues. These days, only 2 small VMs remain but are now under scrutiny as well, as Hetzner has significantly increased prices for them. To make matters worse, such VMs are still advertised Continue reading Netcup Part 1: Tiny VMs For Cheap
Back in 2024 I moved most of my services from a bare metal server in a data center of one provider to a bare metal server in a data center of another provider. In my case, the data center I migrated to was Scaleway and like pretty much everyone else, their bare metal servers are Continue reading Scaleway Bare Metal Server: Removing the RAID
In the previous posts on this topic I have taken a look at over the top voice calling, how much jitter IP packets have when they arrive at the destination and which codec is used. Most over the top voice call options seem to use WebRTC as a general framework for the voice call, and Continue reading Opus and the Jitter Buffer OTT Voice Observations – Part 5
In the previous post, I ve had a look at how to create a new Ubuntu 26.04 installation with an encrypted system partition and a separate partition for the user directory that is also encrypted. A cool way to get this done is to bring up an installation in a virtual machine first and then move Continue reading Ubuntu 26.04 – An Encrypted Separate Home Partition Part 2
