Build from source log

Is this a normal Fedora 29 installation? When I update the one here I get kernel 4.18.18-300.fc29. Does the same thing happen if you create a Fedora 29 installation from scratch? Obviously this is something I can test too, but it might be a long time until I get to it due to other tasks.

[Vyacheslav]

This build by packer (I use kickstart for install)
I update system to last kernel before install
You can remove vagrant-cloud from post-processor in packer.json
And create
folder http with ks.cfg file
folder scripts with bootstrap.sh file
And run packer build -debug -var "headless=false" packer.json

I'm afraid that we can't support non-default uses of our code on the bug tracker. (The vbox-dev mailing list might be a better place.) It is certainly great to see it happening, just that we don't have the resources for helping.

My quick guess is that you tried to use vboxsf without vboxguest, which it depends on, but I would rather not follow this up further on the bug tracker.

[Vyacheslav]

Ok, I download fedora 29 netinstall from fedora site
​https://download.fedoraproject.org/pub/fedora/linux/releases/29/Server/x86_64/iso/Fedora-Server-netinst-x86_64-29-1.2.iso
Install fedora with default options without any modifications
And I get kernel 4.19.5-300.fc29.x86_64
Then I login as root and mount VBoxGuestAdditions iso and install dev packages

dnf install kernel-devel gcc elfutils-libelf-devel
mount /dev/cdrom /mnt
cd /mnt
./VBoxLinuxAdditions.run

VirtualBox Guest Additions: modprobe vboxsf failed
lsmod | grep vbox
vboxguest 40960 2
vboxvideo 45056 1
drm_kms_helper 196608 1 vboxvideo
ttm 131072 1 vboxvideo
drm 487424 4 drm_kms_helper,vboxvideo,ttm

modprobe vboxsf
modprobe: ERROR: could not insert 'vboxsf': Unknown symbol in module, or unknown prameter (see dmsg)

Try rebooting. Fedora 29 already has a copy of vboxguest which is not compatible with ours.

[Vyacheslav]

Yes reboot help
So I need ignore this error in packer because after restart all work. Thanks
