Hi,
anyone tried to custom an image for Azure from Index of /vault/rocky/8.4/images/ (rockylinux.org)?
My purpose is to push custom Rocky image into Azure and create my VMs from generic qcow2 image.
I tried to use the cloud-init from az vm create cli as mentionned in the documentation: Tutorial - Customize a Linux VM with cloud-init in Azure - Azure Virtual Machines | Microsoft Docs but it did not create any user, launch any command (as a dummy echo commands) or push any ssh public key for a specific user.
In the generic qcow2 image, I don’t know what are the creds for the user root or what is installed within it. Someone has already tried to do it or has any idea?
Thanks in advance for your help.

Thanks! worked on Proxmox
Has anyone tried this procedure on Rocky 9.0? My kvm is stuck at the boot screen saying “Booting from Hard Disk …”
edit: I was executing these commands, basically adamaze’s last 2 commands:
virt-customize \
--add /var/lib/libvirt/images/x13.qcow2 \
--hostname x13 \
--ssh-inject "root:file:/root/.ssh/id_rsa" \
--uninstall cloud-init \
--selinux-relabel
virt-install -n x13 \
--os-type=Linux \
--os-variant=centos8 \
--ram=4 \
--vcpus=2 \
--disk path=/var/lib/libvirt/images/x13.qcow2,bus=virtio,size=20 \
--network bridge:virbr0 \
--graphics vnc,listen=0.0.0.0 \
--import --noautoconsole
with version 8.6, the above definitely works.
The new rocky9 image uses UEFI, so you have to add “–boot uefi” to your command

Works like a charm, thanks!
Hello, one my side it is not working.
I’ve got a cpu at 100% and no VNC
Here are my setup:

Do I miss something ?
Many thanks.

I reply to myself to help everyone.
I use two stacks.
The first one is a Fedora Workstation 37 running under VirtualBox from Windows.
I’ve got VTX nested checked under my processor tab into VirtualBox.
In /etc/modprobe.d/kvm.conf I have got kvm_intel nested=1 uncommented
When running Rocky Linux 9 VM under kvm under Fedora I keep having Guest has not initialized the display (yet) and cpu keep being at 100%
=> So it is not working
The second stack is a real instance of Fedora Workstation 37
=> I get my Rocky Linux 9 VM under kvm working 
Here are my configuration finally used (I do not need UEFI to make it works)
