GNU Linux Debian 11 - Gnome Boxes - an Open Source VirtualBox replacement?
In search for alternatives, decided to test drive “gnome boxes“, which is said, to be an easy-going gui for the libvirt qemu virtualization system.

Description: Simple GNOME app to access remote or virtual systems
GNOME Boxes is a desktop client to view or use local virtual machines,
remote physical machines, or remote virtual machines.
Boxes is intentionally simple and easy to use.
Hardware virtualization is required to use local virtual machines.
as minimalistic as the description is the gui:
indeed nothing against a bit of gui minimalism…
kvm is developed by Redhat… that’s why it is right there on top… but there is more for “easy” or “instant” install…
would have been nice, if the disk size can be directly entered in numbers as well…
also a checkbox for “thin provisioning” would have been nice
but it definately works
the vm properties tab, might be a bit too minimalistic… when changing vm settings afterwards, the user will have to rely on the user’s xml editing skillz ;-p
this isa nicely done overview screen… showing real time thumbnails of the all vm’s current desktop…
when almost finished installing Debian 11… gnome boxes skips the “where to install grub” screen and reports “debian 11 is ready to use”
but it won’t boot X-D
just in case if the cursor is “stuck” it can be released by hitting Ctrl+Alt
the gui minimalism is a nice try, but gnome-boxes got some quality issues there, not ready for use with Debian, not ready to replace redhat’s kvm’s excellent virtmanager, which works flawless under GNU Linux Debian and has way more settings to modify vms

QEMU >= 7.0.0 changes split package setup
2022-05-09 - David Runge
With the update to qemu 7.0.0 the package has been turned into a more fine grained split package utilizing meta packages.
The qemu package is now virtually provided by the meta packages qemu-base, qemu-desktop and qemu-full.
The functionality of qemu prior to 7.0.0 is replaced by qemu-desktop
The functionality of qemu-headless is replaced by qemu-base
The functionality of qemu-arch-extra and qemu-headless-arch-extra is replaced by qemu-emulators-full
The meta package qemu-full provides all QEMU related packages (excluding qemu-guest-agent)

Venus on #QEMU : Enabling the new virtual #Vulkan driver • Tux Machines ⇨ http://www.tuxmachines.org/node/158428 #GNU #Linux #TuxMachines
Tried an interesting experiment this morning where I built an #amd64/#arm64 #Docker image of Diaspora, which heretofore had always been just an amd64 image. Building this on an arm64 laptop meant that all the amd64 stuff took place in (quite slow) #qemu emulation. Here are the timings for the two builds, which #BuildKit runs in parallel. You can see the commands and architectures, and how long each took to run:

kvm-qemu - where to set the chipset?
it is actually like this, in virt-manager, that chipset and bios can only be changed during first setup "begin installation" it then is fixed and can not be changed in virt-manager

- first off the praise:
- kvm-qemu is a high performance nicely scriptable virtualization system
- if it works, it can do pretty things 🙂
- especially like the x11 forwarded virt-manager gui over ssh (yes it is a bit slow… but simplicity at it’s best)
- now the critique:
- it does not feel very user friendly X-D
- why is thin provisioning not the disk-saving default option?
- or at least should be possible for the user to select this option in virt-manager
- do not drop windows 7 support just yet… many virtualization systems such as VirtualBox are actually intended to run “outdated” OS on newer hardware for the sake of getting programs to run, that are incompatible with recent OS.
- please double check that virtio 64Bit drivers actually work under win 7 64bit (home, pro and ultimate)

something is pretty off here.
it all starts of with virsh-manager not detect Windows 7 iso correctly, and having to chose it manually enabling the legacy checkbox.
the idea was to install:
- Windows 7 64Bit Ultimate
- SP1
- - Windows 7 Service Pack 1 (32 Bit)
- Windows 7 & Server 2008 R2 Service Pack 1 (64 Bit)
- Windows 7 & Server 2008 R2 Service Pack 1 (ISO-Image, enthält 32-, 64-Bit und IA64)
- - Windows 7 Service Pack 1 (32 Bit)
- WinFuture Update pack
actually managed to install it once… but when trying to install the updates, things became very very slow aka stuck.
next try… it won’t go over this screen: “windows files are being extracted 0%” just sits there doing nothing.
what worked: virtio & 32Bit
the only success that can be reported is for 32Bit! (virtio-win-0.1.173.iso being the last version supporting Windows 7)
now the performance is pretty decent X-D (of course this is all RAM cached stuff)
no chance to select any 64Bit drivers!? in any virtio iso!?
