Hi Mark, For a number of years now I've used QEMU/KVM, via libvirt and associated clients: virt-manager (Gnome GUI), and the CLI tools in libvirt-clients package (in particular virsh). There's this available from RedHat on using virsh for remote admin that provides a good intro: https://www.redhat.com/sysadmin/virsh-subcommands ..and this walk through of creating a VM from an ISO.. https://adamtheautomator.com/virsh/ your chosen web search engine and 'virsh tutorials' is your friend as usual ;) HTH, Phlash.

Boot to a web browser (nothing else available)
by Mark Rogers 03 May '23

03 May '23

I need to set up an Ubuntu 22.04 box so that on startup it enters a graphical environment with a web browser showing a specified page. No access to other applications. (I'd call this a "kiosk" configuration but having spent some time with Google that phrase can mean different things so I wanted to be clear). There's going to be quite a lot of other stuff going on behind the scenes in support of the web interface but I have all that working. It's just the boot-to-browser bit that's an issue. It's not public facing and I don't care if the boot sequence is visible, provided that as long as the box is left alone for a couple of minutes it will eventually end up at a web browser directed to localhost. I've done stuff like this before but Ubunti 22.04 uses snaps rather than .deb packages and that changes the way the applications interact with the O/S - previously I've had systemd start lightdm start a bash script which starts Chromium or Firefox in kiosk mode, but it doesn't seem possible that way any more. But the reality is that I don't need a minimal install so I may well have overthought things in the past. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

KVM/QEMU
by Mark Rogers 02 May '23

02 May '23

I've used VirtualBox for years, most recently either as a desktop tool (eg on a laptop) for testing things out (managed by the VBox GUI), or as a server tool hosting multiple VMs (managed via a combination of CLI and the web-based phpVirtualBox tool which mimics the VBox GUI via a web interface). For a long time I've thought I should use KVM instead so today I had a crack as installing it on my home Linux server (Ubuntu) but I've gone around in circles and got nowhere useful. What do I need to do to achieve something simple like creating a new VM, booting it from a Windows ISO and installing Windows 10 on it? I need to do it all from the command line or via a web interface - preferably having both options open to me. The server is headless so a traditional GUI is no use to me. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

No pdf thumbnails
by Bev Nicolson 15 Apr '23

15 Apr '23

I'd not been having any trouble with pdf's for a while but suddenly no recent pdf's show a thumbnail, just an Adobe logo. I've got Master pdf and the simpler Evince (for when I just want to read something.) In the past, if this happened, all I had to do was change the file name and then a thumbnail would appear. That doesn't work here. (I think I've asked a similar question before but on hunting through the archive couldn't see a clear answer.) Bev

Has anyone here used qawebhosting or know anything about them?

I'm looking for a hosting service for a few web sites that I maintain for friends and family. One possibility is QA Webhosting who seem to be quite small but offer just about exactly what I want/need. Does anyone here know anything about them? -- Chris Green

Linux Tablets
by Peter Berrie 22 Mar '23

22 Mar '23

I recently had occasion to wish, yet again, that I had a proper Linux tablet. So afterwards I dug out an old Linx 8 windows tablet and tried various distros on it. It came with windows 8, which was pretty bad, and I had upgraded to windows 10, which is better but glacially slow. I tried various distros on it including several Puppies, some of which not bad but no touch support, Fedora, which would not finish booting, slitaz (failed to boot), MXlinux (no touch). Several others. Zorin (failed to boot). A desktop derived from Alpine. So far the best I have found is Peppermint 32 bit. XFCE. Touch works, it sees battery status, its reasonably fast considering the hardware. I haven't got on screen keyboard yet, but there seem to be several choices of this. My impression is that it would be a viable solution on a more recent and powerful x86 tablet. But which? I'm thinking now about getting a used Surface. It seems like the Surface 5 is the best choice among them, apparently a significant improvement on the model 4, and that it should work with Linux. It should be able to manage Fedora which is widely recommended for touch devices. There is also a Lenovo with detachable keyboard of lower cpu spec and similar vintage, at about the same price. Lenovo Ideapad Miix 700. Bigger screen. The Surface 5 seems to have been a significant upgrade from the previous Surface 4. Do you all have any thoughts about this? Any other x86 tablets to consider? Any other distros that are more promising than Peppermint? Is Chrome worth considering? Peter

Hi, Some one (not me) has been "messing about" !! During a phone discussion with [1] at fasthosts we retried sending the previously bouncy emails. AND THEY WORKED !! The magic gremlins appear to have fixed it. What can I say? Thanks to all who put in effort. (no doubt it'll break again tomorrow) Nev On 06/03/2023 17:17, steve-ALUG(a)hst.me.uk wrote: > On 06/03/2023 16:54, Nev Young wrote: >> Hi Steve, >> >> This is too hard for my ikkle brain. > > Hi mate. > > Will have a look and get back to you. > > Just a mo... > > Steve

HP Microservers or similar
by Mark Rogers 20 Feb '23

20 Feb '23

Over the years I've used a handful of HP Micro servers to run a Linux-based web server application. To be honest I suspect it would comfortably run on a Pi, to give you some idea of power requirements. However it does need to be dependable and one of the criteria is RAID (software RAID 1 is fine). We replace the hardware every few years so the question I have is: what is a good small server for Linux these days? Apart from the requirement to host 2 SATA drives there isn't much in terms of hardware requirements. We don't even use a lot of disk space - maybe a few dozen GB. One HDD gets replaced annually so that no disk is older than 2y, using commodity disks in the 1-2TB range but partitioned to only use 200GB on each disk, just because we don't need more and it makes the swap to a new disk quicker. Hot swap not needed. Would consider SSD for the new server. I was about to get a quote for an HP Gen10 MicroServer when it crossed my mind that maybe just buying the same server out of habit wasn't necessarily the right approach! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
