Templates for RHEL 8 and CentOS 8 on XCP-ng #274

agador · 2019-09-18T17:22:32Z

Are there going to be templates for REHL 8.0 and CentOS 8.0 VM installs? I realize CentOS 8.0 isn't going to be released for a couple more days, but REHL 8.0 has been out for a while now.

Are they necessary to creating VMs with REHL 8.0 or CentOS 8.0 media?

It's not vital. You can use a RHEL 7 template, it will work fine. However, we'll see to add those templates.

Thanks Oliver!

stormi · 2019-10-16T08:25:06Z

I have added templates for RHEL 8 and derivatives, as well as a template for Debian 10 (In XCP-ng 8.0).

You can test them by installing the update candidate:

yum update guest-templates* --enablerepo=xcp-ng-testing

stormi · 2019-10-16T08:39:09Z

Note: there's also an update candidate for guest tools for RHEL 8 and derivatives:

# first make sure to eject the tools ISO image from existing VMs

# then:
yum update xcp-ng-pv-tools --enablerepo=xcp-ng-testing

Question on the forum "installed and tried to use a centos8 template. It does not allow to use UEFI. Is this intended?".

Yes, because UEFI support is still experimental, and the template is meant for the larger use cases. You can still use the "Other installation media" template, it will work the same. Is that important to you?

Also, the new REHL/CentOS 8 templates are not showing in XOA.

Oops.. missed a step with the templates.

Also, the of note.. the new tools disk is lightly greyed out in XOA

agador · 2019-10-16T12:27:20Z

Ok.. so after a pool-reboot, the tools-cd now shows up and attaches correctly. First I tried a xe-toolstack-restart... that did NOT work.

It took a complete pool boot to get the CD to show up correctly and attach as expected.

Other than that... both the templates and the tools-cd work just fine for CentOS 8.

Thanks!

cnaumer · 2019-10-18T12:33:06Z

installed and tried to use a centos8 template. It does not allow to use UEFI. Is this intended?

stormi · 2019-10-18T13:04:26Z

Quoting what I answered above to this question:

Yes, because UEFI support is still experimental, and the template is meant for the larger use cases. You can still use the "Other installation media" template, it will work the same. Is that important to you?

cnaumer · 2019-10-18T13:34:00Z

No this was just an observation. I have no Problem with that.
Tried the template now for a centos8 install and everything worked so far.

nagilum99 · 2019-10-18T14:23:46Z

Question for yourself: What sense does it make, to write down this observation, as it was already mentioned (and your question answered) here?

cnaumer · 2019-10-18T14:28:45Z

None at all. Note to self -> read all comments before posting
