Hi All,
Fedora has received a bug report here:
https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.r...
That Fedora rawhide VMs no longer boot under the VirtualBox hypervisor after the VM has been updated to a 5.18-rc# kernel.
Switching the emulated GPU from vmwaregfx to VirtualBoxSVGA fixes this, so this seems to be a vmwgfx driver regression.
Note I've not investigated/reproduced this myself due to -ENOTIME.
Thanks for letting us know. Unfortunately we do not support vmwgfx on VirtualBox. I'd be happy to review patches related to this, but it's very unlikely we'd have to time to look at this ourselves.
I somewhat understand where you are coming from, but this is not how the kernels "no regressions" policy works. For the end user a regression is a regression and as maintainers we are supposed to make sure any regressions noticed are fixed before a new kernel hits end user's systems.
At a minimum it would have been good if you had tried to at least reproduce this bug by installing Fedora rawhide inside an actual vmware VM. I've just spend a couple of hours debugging this and the bug definitely impacts vmware VMs too; and thus very likely also reproduces there.
I've a patch fixing this, which I will send out right after this email.
Regards,
Hans
