Compatibility with Windows seems a lot better in 7 compared to 6, both as host and as guest. They also seem to have added a number of features such as secure boot. It seems that there was quite a time gap between 6 and 7 so a whole lot of changes built up.

Whether those things matter to you, or not, is in the eye of the beholder.

I'm using it now and appears to work well on Manjaro, but I had to roll back from a rt kernel I was trying because it couldn't build the necessary modules. I would migrate to virt-manager in a second if directory and clipboard sharing wasn't that convoluted requiring multiple reads/watches of manuals and videos to do what on Virtualbox has been a lot more intuitive for ages. (solution: never ever let developers design user interfaces :^)

I tried it last week, and it was a terrible experience. I used one of the official windows eval VMs, it was crashing all the time, and when it ran, it was laggy, with a lot of visual bugs.

My guest is a Fedora laptop with AMD CPU and GPU, and running the same VM with VMWare worked like a charm.

I lost about a day trying to debug packer builds of vagrant boxes for vbox last week. The vbox builds were glacially slow and would reliably fail at rebuilding the tools dkms components.

That was on 7.0.8 I think. "Lucky" me 7.0.10 was released that same day, but didn't show up in an update check. I just happened to see the reference on their site to 7.0.10 and it resolved both issues from the previous day.

I don't have much day to day use to report with it though, I don't use the vbox images much myself.

I tried it when I re-installed my workstation with Kubuntu 23.04. It was a shit-show of invalid links and errors when I tried to get the extensions and runtime modules for the VM's. After about 45 minutes I purged it and installed libvirt and Virtual Machine Manager.

I've been using 7.0.x for over half a year, currently on 7.0.8, on a Windows host. Most of my guests were installed during 6.x and have continued to run fine on 7.0.x, and new guests made in 7.0.x run and behave normally. No problems on my end.

I use 7.0.x for an old Debian install (3.1), FreeBSD and Windows (all guests, the host is Windows 11 or Fedora 37). All seem to work fine, at least none of the major issues that thread brings up (3daccel on windows, broken efi, etc).

I had to reinstall all machines from V6 in V7. None (Linux and Windows) worked really good, crashes all the time.

Fresh new install works good.

Only Windows-Guest under Linux-Host had some graphical issues.

I'm running 7.0.8 both directly and via Vagrant.

Everything is working as it should in my case.

P.S.: I'm using Debian's packages via unstable.

Installing the older 6.1.x guest additions and disabling GPU acceleration fixed all the bugs for me guests

I've had issues with 7.x. Can't boot anything on my Fedora host.
