RHEL 7.4 Fail to run full screen in Virtualbox
Good day
I am trying to run RHEL 7.4 in Oracle Virtualbox 5.1.26 but I cannot get it to run in full screen mode.
Based on the terminal output the Virtualbox guest additions seems to install fine, but RHEL 7.4 cannot go above 1024 x 768
I am now at my wits end and would really appreciate some advice as to how to get RHEL 7.4 to run fullscreen.
Thanks in advance Red Hat Heroes.
EDIT: Added Virtualbox log file.

Hi George,
We have the same issue here. There is no solution for this using VirtualBox 5.1.x. I'm using the VirtualBox 5.2 Beta 2 which supports RHEL 7.4.

Hi George,
You can try KVM instead - everything works out-of-the-box and way faster.
To install it execute : sudo yum install qemu virt-install virt-manager
Then reboot the host system in order to properly make use of KVM virtualization.
KVM outperforms vbox and there's no need to install any proprietary guest additions.
Cheers :)

Thanks Christian for the feedback, much appreciated. Unfortunately we are using Windows hosts on this site and not Linux hosts.

Hi George,
while it is a BETA it's not unlikely to experience some issues. During yum update the kernel was updated, too.
kernel.x86_64 3.10.0-693.el7
kernel.x86_64 3.10.0-693.1.1.el7
After rebooting the system the vbox kernel module was broken again. I had to mount the vbox-addition.iso and reinstall the vBox Additions to get it working again.
I expect to do this after each kernel update to come. I do not have an Oracle Web Account and do not like to get one. So I'm unable to discuss this issue with the guys from VirtualBox.

Hi Jörg,
This is one of the downsides of vbox, every time the kernel gets updated, you have to reinstall the guest additions. As I switched from Debian based systems to Red Hat based systems some time ago and dropped vbox completely in favor of KVM virtualization, where something like this is not necessary, I'm not sure if the following solution will work, but in the days when I used ORACLE VirtualBox on ubuntu (and Windows) hosts, I used the following workaround :
Install dkms (dynamic kernel module support) in the RHEL 7.4 guest system, execute sudo yum install dkms. For whatever reason this installs the kernel-debug-devel package as a dependency, but you would need the kernel-devel package. Install that package alongside, execute sudo yum install kernel-devel and reboot the guest system afterwards. From now on you (hopefully) won't have to reinstall the guest additions anymore.

Hi Christian,
do you know in which repo the dkms packages is? At the moment I've enabled rhel-7-server-rpms, only. There is no dkms package.
I couldn't find it via Package-Browser, either.
Running Ubuntu in VirtualBox is a lot easier. My Destkop is a Windows Host. So using KVM is no option.

Hi Jörg,
The dkms package is available in EPEL, so you have to add that repository to the software sources ->sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Cheers :)

Thanks Christian,
I've enabled EPEL and installed dkms. After the next kernel-update I will update this thread and let you know if it works.
Cheers,
Jörg
