Moving this blog
I decided to move this blog to Oracle Cloud. I am very satisfied wth my current hosting provider and I plan to maintain my VPS there, but I also have good reasons to move.

Disk technologies and speed
I heard a lot about different disk technologies and how they are getting better all the time. So when I run out of space in one of my computers, the one I'm running my VMs on, I thought I would get the best technology supported.
Moving KVM/QEMU VMs
I often have multiple virtual machines for different purposes. Some I keep idle, some I destroy and recreate when needed, and some I use for actual work and they stay there forever.
Recently I ran out of space. It was not really bad planning on my side, I just didn't have more space to allocate at the moment. I got a new disk to dedicate just to VMs. The new disk is faster but it's not very big; if I'm not careful I will run out of space again.
I decided to move some virtual machines; just the ones that have a GUI. The server based ones that are not interactive can stay in the old and slightly slower disk.
Oracle Cloud challenges
I love challenges, and working with Oracle products has always been a challenge for me. This love/hate relationship started ~20 years ago when I could not set up the first version of Oracle Internet Directory, following the documentation word by word! I had to "fix" several scripts to make it install, and in the end, even though it installed, it still wouldn't work... It was the only product I cared enough to remember that failure after so many years. Or maybe, the only product I failed to tame.
Networking concerns in virtual environments
Some months ago I bought a desktop system. I hadn't had one for years, but a very strange and unexpected need came up; I wanted to play games with my son who lives in Greece, in an attempt to spend a bit more time with him, even virtually. I bought and built a desktop system based on AMD's excellent Ryzen line, but that's for another time. On that computer, and as it would be used predominantly for games, I installed MS Windows. That is another thing that hadn't happened in my household for decades!
SSL certificate revocation gotchas
As you may have heard, Let's Encrypt revoked several certificates today that were issued through a faulty process. Read on for the details, and on how to identify the revoked certificates themselves.
