Latest exciting news : Red Hat Enterprise Linux 8 Beta is open to customers Click on "GET STARTED" to gain access.

Red Hat Blog article : Powering IT’s future while preserving the present: Introducing Red Hat Enterprise Linux 8 Beta

Red Hat Developer article from Mike Guerette (Global Developer Relations Manager at Red Hat) : RHEL 8 Beta is here

More information about RHEL 8 Beta in the Knowledgebase article Red Hat Enterprise Linux 8.0 Customer Beta FAQ.

Edit 2018-12-11 :

I just saw that my information about the System Purpose issue is marked as "Best Response". I haven't marked it as such. I assume that this was done by a Customer Portal system administrator or a Red Hat employee who is responsible for RHEL 8 development. First I thought about un-marking it ... but then I decided to leave it as it is, because the information is somewhat essential to start the RHEL 8 Beta testing at all and all users who enter the discussion immediately can see it.

Trying to install the ISO on a VMWare Fusion 10 and it does not see the target hard drive. So looked on AWS and that release does not have a repo enabled?

Am I missing something?

Dan

Hi Dan,

I don't think that RHEL 8 will be made available on AWS until the final release. The Beta is meant for testing.
Please check if it has something to do with the disk setup. If it is RAID, try to switch it to be in AHCI mode. :)

Regards,
Christian

Dan--

You need to use the SATA hard drive controller, not the default (ancient) LSI Logic SCSI controller in your VM. Had me scratching my head for a few minutes, but I did get RHEL 8 up in VMware Fusion (both 8.5 & 11.0.1) using the SATA controller.

Thanks that worked. I also ran into this nasty ssh issue here: https://bugzilla.redhat.com/show_bug.cgi?id=1624437

Seems there is an issue with VMWare and the ssh client. This one took a while to track down.

Hi James,

I'm running RHEL 8 Beta in a KVM virtual machine with a SCSI controller, and it works as expected.
Might the problem Dan reported be related to VMware, or why does it work properly in my case ? :)

Regards,
Christian

The SCSI driver seems missing. Just switch from SCSI to NVME in the Fusion 10 VM and the disk will show up in Anaconda :).

Martijn.

Hi Martijn,

Thanks for the hint. :)

Christian

That is good news Christian, let me try downloading the image and install it. I see that the binary image looks heavy, it is of size 6.5GB...

Hi Sadashiva,

Yes, quite "heavy" indeed ... I downloaded the ISO yesterday and installed the system. It's running fine so far ... :)

Regards,
Christian

I've seen in the release notes that a number of packages are being removed from RHEL 8 (most notably for me, ImageMagick, an image manipulation library). Is this the "final" list of packages that we can expect to be removed in the release version?

And, on a related topic, is there any reason to believe that feedback at this point will change the decision regarding which packages are included, or have those decisions already been finalized?

Thanks for any insight into the process!

Hi Keith,

Nobody knows which package will be removed in the final release. Red Hat generally doesn't provide information about the decision process, but I think that this list is close to 100 % of what we can expect. To some extend this behavior is necessary, because if they would listen to every single opinion of users, that thing would never reach
final status. An exception though could be when "big customers" require special packages to remain available. :)

Christian

With insights-client I've found, and corrected a misconfiguration : utmp has access to /var/log/lastlog

$ sudo ls -la /var/log/lastlog
-rw-rw-r--. 1 root utmp 292292 18. Nov 14:31 /var/log/lastlog  

Access should be limited to root exclusively - change this with : sudo chown root:root /var/log/lastlog

sudo ls -la /var/log/lastlog
-rw-rw-r--. 1 root root 292292 18. Nov 14:31 /var/log/lastlog  

Hi Christian,

Yes, that is another small change that I also noticed after this. But just changing the group owner of this file doesn't make it persistent as it gets changed after reboot. To make the changes persistent we'd need to edit the lastlog line entry in the file "/lib/tmpfiles.d/var.conf". This is not observed in RHEL7 release.

[root@localhost /]# grep -i utmp /lib/tmpfiles.d/var.conf
f /var/log/wtmp 0664 root utmp -
f /var/log/btmp 0660 root utmp -
f /var/log/lastlog 0664 root utmp -

Since these changes are done/maintained by "systemd", I'd sense it is not ideal to change this manually unless it is absolutely necessary.

Thank you very much, Sadashiva ! :) You are right, I've checked it ... I have set up two systems -
RHEL 8 Server and RHEL 8 Workstation - and on both happened what you've described. I have
checked it on my fedora 29 workstation : the settings are the same there. I agree with you that
we better should leave it unchanged ... eventually the RH Insights team could change this rule.

Christian

In case System Purpose options got set in the Anaconda installer, the system fails to attach a subscription.
So, if that has been done, re-/unset the options by executing these commands to attach the subscription :

sudo subscription-manager role --unset
sudo subscription-manager service-level --unset
sudo subscription-manager usage --unset

sudo subscription-manager register
sudo subscription-manager list
sudo subscription-manager attach --pool=<beta-ID>

There is already a bugzilla report open - this might be a bug or it might be intended during the beta phase.
It states that we can't register a with Developer Subscription when System Purpose choices were selected.

I had trouble in attaching subscription and this helped me. Again Christian your help to the community is truly appreciated :)

But running the command "subscription-manager repos --list-enabled" does pulling out all (disabled) repos as well. It is not actually making any difference between running the command "subscription-manager repos --list". Not sure, if this is also a bug or a glitch on my system...

Thank you very much for the compliment, Sadashiva ! :) I've noticed that too ... it certainly is a bug. :)

I tried installing RHEL 8 Beta on VirtualBox. The installing went fine besides of a strange "light show" at the end of the install. I waited for a while and then did an ACPI shutdown. The install does boot however and I got as far as accepting the agreement but after that, as it tries to boot into graphical environment, it gets stuck in a loop while trying to load GDM.

Has anyone else experienced this? Does anyone know a possible solution?

Hi Jami-Matti,

This should be a drivers issue ... I'm not sure if ORACLE VirtualBox already supports RHEL 8 - but I don't think so.
I suggest that you install RHEL 8 in a KVM virtual machine, which you can manage via Cockpit or Virt-Manager. :)

Regards,
Christain

I was able to install the 8 beta on VirtualBox with no apparent issue. It's probably not fully supported though. I did not see the "light show". You might want to try again.

Yes, it works on Oracle Virtualbox without much problem. You may wish to try to update VirtualBox software to the latest one and then try.

For me, it takes a couple of minutes to bring up the GUI screen and it flickers after loading 'GNOME display manager'. This doesn't look to be an issue, however, there seems to some problem with GNOME, need to try loading other display managers and test this. The VirtualBox version that I'm using is 5.1

Hi Sadashiva, thanks for your information ! Let me add that it is recommended to install the Guest Additions too. :)

Regards,
Christian

I got it "working" by pressing F2 while it's trying to load GDM. This usually brings me to another console for a second or two and then it magically loads GDM.

I haven't found Guest Additions in the default repos. Do I need to add extra repositories to get the VirtualBox Guest Additions?

I'm using the latest version of VirtualBox.

Hi Jami-Matti,

Here is the download link for the latest Extension Pack matching the VirtualBox edition 5.2.22.
If you are using another edition, grab the matching ext-pack from one of the directories here. :)

Regards,
Christian

If you are running GUI on your guest, the easiest way to get GuestAddition is to go to the top menu and click "Devices" and select "Insert Guest Additions CD image...". Then click "Run" to start the installation.

Another way to get the same iso file is to look at your host. It is /usr/share/virtualbox/VBoxGuestAdditions.iso.

Please be sure to have the kernel-devel package installed on the guest system. It is required to build the vbox kernel modules.

Hi Akemi, good explanation from you ... also - having dkms installed is recommended as well. :)

Regards,
Christian

Sadashiva - are you on Windows or Mac (or other)? We've seen some diffs in vbox installation on the two.

Hi Mike, just out of curiosity ... what are those vbox differences you are talking about ? :)

Regards,
Christian

Apologies to be so mysterious. :)

It's still a bit undefined, but it relates to network device drivers. Someone in RH is trying to get the virtualbox upstream to add some.

Thanks for the information, Mike ! :)

Regards,
Christian

The default network adapter that is emulated in VirtualBox is the e1000 (PCI version). The e1000 was listed as one of the removed drivers in RHEL 8 Beta, but fortunately, the driver is in the beta so it works.

It is however recommended to use the virtio driver (paravirtualized networking) for improved performance (less emulation overhead). However, VirtualBox only supports the virtio network adapter on Windows and Linux. So mac users still need to use the e1000.

Sorry for the late reply Mike, I'm on Windows 8.1 version.

I cannot find any compat-libstdc++ packages in the RHEL 8 beta. Is that because RHEL 8 will ship no compat-libstdc++ packages, or is it because I simply haven't searched the right way?

Hi Troels,

Currently compat-libstdc++ is not available in the RHEL 8.0 repositories - it is available for RHEL 7.x though.
https://access.redhat.com/downloads/content/compat-libstdc++-33/3.2.3-72.el7/x86_64/fd431d51/package
So you seem to have searched correctly ... possibly the package gets added later or in the RHEL 8 final release. :)

Regards,
Christian

How about perl-XML-DOM? I don't see it in the list of removed packages, but I cannot find it in RHEL 8 beta?

Hi Troels,

Please check whether a package is currently available for RHEL 8 Beta by using the Red Hat Package Browser. Also, please bare in mind that you are testing a pre-release edition of the operating system. We will have to "wait and see" which packages are included in the final release of RHEL 8.0 and which ones are getting removed from the repos. :)

Christian

Not able to install on VMware Workstation 12 Pro. Unable to select HDD. HDD not detected. While I am able to install on OracleVM

After completion of installation GUI not came up!! I think I need to upgrade my VirtualBox.

Probably the same issue as VMWare Fusion on Mac. Try using the SATA driver not the SCSI driver. Once I chose SATA it worked - see my issue/reply above

I am using VirtualBox 5.2.22 Latest version But same like previous version got stuck at kernel configuration prompt (Configuring kernel-core.x86_64) while installing the OS. I have given 4core CPU, 50GB HDD, 8GB RAM. But not able to get the proper UI. I think this bug need to resolve. ISO download date 23rd Nov 2018 rhel-8.0-beta-1-x86_64-dvd.iso

@Dan Cook, Sure. It works perfectly with SATA driver VMware Workstation 12 Pro.

I like the idea of the application streams. With them I'm able to install different versions of an application from the same repo. If I were able to install different versions in parallel it would be an even better benefit. That would be awesome for migration scenarios.

Hi Jörg,

I agree, the possibility to install different versions of a program in parallel via Application Streams would be great.
Unfortunately it is not possible for technical reasons - the way how dnf/yum works - currently ... but who knows ? Maybe it will be possible to run multiple versions of an application, side-by-side on the system, some later time. :)

Regards,
Christian

It somewhat depends on the package (or in this case the Application Stream). Python36 and Python27 are two separate modules which can be installed in parallel.

Node.js in the current beta has 1 module with two application streams 8 and 10. You can install one or the other.

FWIW, containers are one of the possible answers to the problem of multiple versions - basically giving you a userspace that is specific to the container.

Using containers, especially as non-root, should become easier with podman and buildah and getting away from the big daemon.

https://developers.redhat.com/blog/2018/11/20/buildah-podman-containers-without-daemons/

Hi Robert,

Thanks for your interesting input and for providing further details about Application Streams.
Podman might be a suitable solution, I agree ... I've already done some testing and it seems to
work fine so far. What I especially appreciate is that you can use it as standard user and that it
runs it without a daemon, an alternative solution which (for most cases) can replace docker. :)

Christian

Hi Apurva,

A "general repo" doesn't exist : "Successfully attached a subscription for: Red Hat Developer Subscription"
It means that you have attached this subscription, so you are currently using the stable RHEL 7 edition. :)
