Build virtualbox in fedora35

by

Download VirtualBox source and extract it to /home/work/vb/VirtualBox-6.1.32.

Involve qt,

# read in ./configure
#	for q in $QT5DIR "$DEVDIR/linux.$TARGET_MACHINE"/qt/v5.*; do
# so download qt5.9.2 and install to /home/work/qt/Qt5.9.2
wget http://download.qt.io/archive/qt/5.9/5.9.2/qt-opensource-linux-x64-5.9.2.run
# make a link to qt5.9.2
cd /home/work/vb/VirtualBox-6.1.32/tools/linux.amd64
mkdir qt
ln -s /home/work/qt/Qt5.9.2/5.9.2/gcc_64 `pwd`/qt/v5.9.2

Build it,

# must add '--skip-broken', or else our fedora os will be mute curiously, suddenly
# in the subsequent experience.

cd /home/work/vb/VirtualBox-6.1.32

# modify ./configure

# RTAssertShouldPanic error: this statement may fall through [-Werror=implicit-fallthrough=]

./configure --disable-hardening --disable-docs --disable-java
source ./env.sh
kmk BUILD_TYPE=debug -j 1

how to run,

cd out/linux.x86/release/bin/src
make
sudo make install

#sign generated vbox kernel modules

cd ..
export LD_LIBRARY_PATH=/home/work/qt/Qt5.9.2/5.9.2/gcc_64/lib:LD_LIBRARY_PATH
./VirtualBox

VERR_VM_DRIVER_NOT_ACCESSIBLE? 

chmod ugo+rw /dev/vboxdrv

The VM session was aborted?

Maybe we forgot load vboxnetadp and vboxnetflt,

#modprobe vboxdrv
#modprobe vboxnetadp
#modprobe vboxnetflt

or the shared folder locates in U-disk but we have not mounted it.

Where to get guest additions iso?

http://download.virtualbox.org/virtualbox/6.1.32/VBoxGuestAdditions_6.1.32.iso

But why my Fedora os often drops dead?

What can make system dead must be that the modules we insert to kernel have problem.

The correct way to insert modules is that we should install official bundle first which will insert an configuation file in /etc/udev, modify /etc/udev/rules.d/60-vboxdrv.rules, give current user read and write permission and reboot system that will effect the rule. Then install the vbox*.ko we built.
