Start serial QEMU RHEL 9.2 guest VM installation.
$ sudo \
virt-install \
--name epidote \
--memory 8192 \
--disk vol=iscsiadd02/epidote.qcow2 \
--vcpus 4 \
--os-variant rhel9.2 \
--graphics none \
--location /iscsiadd02/images/rhel-9.2-x86_64-dvd.iso \
--extra-args 'console=ttyS0'
NOTE: For pre-RHEL 9 guest VM, you could use an extra option:
--console pty,target_type=serial \
and a different --extra-args parameter:
--extra-args 'console=ttyS0,115200n8 serial'
As of time of this writing, when you install RHEL 9 guest VM with virt-install(1) with --console pty,target_type=serial and --extra-args 'console=ttyS0,115200n8 serial', you will see this warning:
'serial' is deprecated and has been removed.
To change the console use 'console=' instead.
Continuing with VM guest installation:

Starting installer, one moment...
anaconda 34.25.2.10-1.el9_2 for Red Hat Enterprise Linux 9.2 started.
* installation log files are stored in /tmp during the installation
* shell is available on TTY2
* if the graphical installation interface fails to start, try again with the
inst.text bootoption to start text installation
* when reporting a bug add logs from /tmp as separate text/plain attachments
================================================================================
================================================================================
Text mode provides a limited set of installation options. It does not offer
custom partitioning for full control over the disk layout. Would you like to use
VNC mode instead?
1) Start VNC
2) Use text mode

RHEL subscription-manager – Client Registration via Red Hat Satellite (RHS)
$ hostname
example.com
Installing katello-ca-consumer
$ sudo \
yum \
install --nogpgcheck \
http://satellite6.example.com/pub/katello-ca-consumer-latest.noarch.rpm
Registering the Client
Once katello-ca-consumer is installed, proceed with the registration:
$ sudo subscription-manager register --org=YourOrgName --activationkey=<ACTIVATION_KEY_NAME>
$ sudo yum -y remove rhn-setup rhn-client-tools \
yum-rhn-plugin rhnsd rhn-check rhnlib spacewalk-abrt spacewalk-oscap \
osad 'rh-*-rhui-client' 'candlepin-cert-consumer-*'
In this case, the OS is RHEL 9. Activation key name for RHEL 9 OS is: RHEL9
Example for registering a Red Hat Enterprise Linux 9 system:
$ sudo \
subscription-manager register \
--org=YourOrgName \
--activationkey=YourActivationKey
The system has been registered with ID: 0404e570-5090-4232-9568-9b99723e6efb
The system has been registered with ID: 0404e570-...........................
The registered system name is: example.com
$ sudo yum -y remove rhn-setup rhn-client-tools \
yum-rhn-plugin rhnsd rhn-check rhnlib spacewalk-abrt spacewalk-oscap \
osad 'rh-*-rhui-client' 'candlepin-cert-consumer-*'
Host Tools
Ensure the katello-host-tools package is installed from the Satellite Tools repository on Satellite Server. This package helps in reporting back to Satellite and informs of current patch levels and general state of your host. Note, the repository is Satellite version dependent. When Satellite is upgraded, the repository name will change to correspond with the new Satellite Server version.
$ sudo subscription-manager repos --enable satellite-tools-6.10-for-rhel-8-x86_64-rpms
$ sudo yum -y install katello-host-tools
$ sudo systemctl stop goferd.service
$ sudo systemctl disable goferd.service
$ sudo yum remove katello-agent
List the repo IDs of the currently subscribed repositories:
$ sudo subscription-manager repos --list-enabled | grep ID | awk -F' ' '{ print $3 }'
rhel-9-for-x86_64-appstream-rpms
rhel-9-for-x86_64-baseos-rpms
List all installed packages.
$ sudo yum list installed | wc -l

NOTES
---- snip ----
Several virsh commands take an optionally scaled integer; if no scale
is provided, then the default is listed in the command (for historical
reasons, some commands default to bytes, while other commands default
to kibibytes). The following case-insensitive suffixes can be used to
select a specific scale:
b, byte byte 1
KB kilobyte 1,000
k, KiB kibibyte 1,024
MB megabyte 1,000,000
M, MiB mebibyte 1,048,576
GB gigabyte 1,000,000,000
G, GiB gibibyte 1,073,741,824
TB terabyte 1,000,000,000,000
T, TiB tebibyte 1,099,511,627,776
PB petabyte 1,000,000,000,000,000
P, PiB pebibyte 1,125,899,906,842,624
