You can't alter the kernel parameters from libvirt as the image loads
its own kernel, but you can alter the parameters at their grub screen.
Try to open the console proxy as soon as possible and hit up or down
arrow so grub doesn't proceed, then hit "e" key (I think) to edit the
appropriate vmlinuz entry.
My hunch is that this being a generic image (made mostly with EC2 and
possibly Openstack in mind) they send all output to a serial console
instead of vga, so you would need to remove any parameters such as
console=ttyS0 and then boot it.

I'm trying to boot a Rocky cloud image for Rocky 9.1 using their qcow2
image.
As soon as I start the VM, I get:
"Probing EDD (edd=off to disable)... ok"
and then nothing. I don't see a DHCP lease being pulled, so I assume
the VM isn't actually proceeding with boot.
Anyone else see this? This is on Cloudstack 4.17.1.0. I posted a
similar message on the Rocky mail list. Is there an easy way via virsh
or cloudstack to alter the kernel command line parameters in an
existing image before it boots?
Thanks
