You cannot create a sealed virtual machine template based on a RHEL 8.0 virtual machine in Red Hat Virtualization 4.3, because of the following limitations:
* libguestfs tools on Red Hat Enterprise Linux 7 do not support modifying Red Hat Enterprise Linux 8 disk images because of additional XFS functionality added in Red Hat Enterprise Linux 8.
* Red Hat Virtualization 4.3 does not support hypervisors based on Red Hat Enterprise Linux 8.0

See also https://bugzilla.redhat.com/show_bug.cgi?id=1671895 I NAKed it, but it may be possible in mixed clusters assuming we can target an EL8 host. Not until 4.4 running in compatibility level 4.3 (where we will still have EL7 hosts), and I'm not optimistic Please set priority/severity for this. This is based on BZ 1684147. Summarizing the comments from that bug: I'll add a note to the Virtual Machine Management Guide in chapter 7 "Templates" under [1] and [2] saying: [NOTE] ==== You cannot create a virtual machine template based on a RHEL 8.0 virtual machine in Red Hat Virtualization 4.3, because of the following limitations: * Red Hat Virtualization 4.3 does not support template sealing for Red Hat Enterprise Linux (RHEL) 8.0 virtual machines. * libguestfs tools do not support RHEL 8.0 virtual machines. ==== [1] https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html-single/virtual_machine_management_guide/index#Sealing_a_Linux_Virtual_Machine_for_Deployment_as_a_Template [2] https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html-single/virtual_machine_management_guide/index#Creating_a_template_from_an_existing_virtual_machine Liran, please review my implementation of your comments. I'd suggest something like: [NOTE] ==== You cannot create a virtual machine template based on a RHEL 8 virtual machine in Red Hat Virtualization 4.3, because of the following limitations: * libguestfs tools on Red Hat Enterprise Linux 7 does not support modification of Red Hat Enterprise Linux 8 disk images due to additional XFS functionality added in Red Hat Enterprise Linux 8 * Red Hat Virtualization 4.3 does not support Red Hat Enterprise Linux 8 hypervisors (In reply to Ryan Barry from comment #4) > I'd suggest something like: > > [NOTE] > ==== > You cannot create a virtual machine template based on a RHEL 8 virtual > machine in Red Hat Virtualization 4.3, because of the following limitations: > > * libguestfs tools on Red Hat Enterprise Linux 7 does not support > modification of Red Hat Enterprise Linux 8 disk images due to additional XFS > functionality added in Red Hat Enterprise Linux 8 > * Red Hat Virtualization 4.3 does not support Red Hat Enterprise Linux 8 > hypervisors Fixed. Eli, please do a peer review of the merge request: https://gitlab.cee.redhat.com/rhci-documentation/docs-Red_Hat_Enterprise_Virtualization/merge_requests/1439 The note appears in the following two places: https://pnt-devops-rad-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/ccs-mr-preview-prod/5411/artifact/doc-Virtual_Machine_Management_Guide/preview/index.html#Sealing_Virtual_Machines_in_Preparation_for_Deployment_as_Templates https://pnt-devops-rad-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/ccs-mr-preview-prod/5411/artifact/doc-Virtual_Machine_Management_Guide/preview/index.html#Creating_a_template_from_an_existing_virtual_machine (In reply to Steve Goodman from comment #6) > Eli, please do a peer review of the merge request: > > https://gitlab.cee.redhat.com/rhci-documentation/docs- > Red_Hat_Enterprise_Virtualization/merge_requests/1439 > > The note appears in the following two places: > > https://pnt-devops-rad-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/ccs-mr- > preview-prod/5411/artifact/doc-Virtual_Machine_Management_Guide/preview/ > index. > html#Sealing_Virtual_Machines_in_Preparation_for_Deployment_as_Templates > https://pnt-devops-rad-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/job/ccs-mr- > preview-prod/5411/artifact/doc-Virtual_Machine_Management_Guide/preview/ > index.html#Creating_a_template_from_an_existing_virtual_machine Looks good.

Fixed. Now it says: You cannot create a sealed virtual machine template... I'm moving this to verified because everyone has signed off and since this is not a procedure, it doesn't require a QE check.
