Yes it is.
Have been running Win11 in VBox for half an hour – nice and smooth.
EDIT:
Maybe not; I’ve had some unexpected restarts that I don’t think were Windows’ fault.
Looks like we have to wait for vbox 6.1.35; it’s in testing, and some fedora users report that it works, in this forum.
The VM files don´t get corrupted by anyway (even though running it through those mentioned kernels in those mentioned VirtualBox’s version become VERY unstable regarding memory issues);
Downgrading to virtualBox 6.1.32 or even 6.1.30 didn’t make it for me;
Upgrading my kernel to the 5.15 LTS didn´t make it for me (I was originally on 5.10 LTS);
Upgrading my kernel to the non-LTS 5.18 brought everything back to normal (so far).
Also noticed the issue on a haswell laptop (i7-4750HQ). Virtualbox crashes windows guests, unless kernel 5.18.5 is used.
This seems weird. Problems are generally expected with recent kernels. Conversely in this case VirtualBox seems to have problems with the least recent kernels where patches were backported via the kernel stable branches. These are never expected to cause regressions of this sort.
First I tried upgrading to linux518 and even to linux519, but none of these helped. Then I decided to go downgrading. I downgraded 4 packages from cache like this: # pacman -U file:///linux517-5.17.9-1-x86_64.pkg.tar.zst file:///linux517-headers-5.17.9-1-x86_64.pkg.tar.zst file:///linux517-virtualbox-host-modules-6.1.34-9-x86_64.pkg.tar.zst file:///virtualbox-6.1.34-2-x86_64.pkg.tar.zst
And it worked. My Windows 10 came back to life!
I’ll stick to this workaround until the official fix released.
Kernel 5.18.14-1. Updated virtualbox to 6.1.36-1 and all its dependencies, but my windows 10 virtual machine still doesn’t start. I keep seeing this screen. Any ideas, guys?
I also went back from 5.18 to 5.15 (LTS), because virtualbox 6.1.36-1 works on both
