Using packer and type qemu in the json file to create a RHEL 8.4 guest kvm vm, but ssh timeout error coming
Pravin Kumar
I have RHEL 8.5 as the KVM host. I want to create a guest vm of RHEL 8.4 through packer type qemu and have a json file where all the configurations are mentioned.

}
It is working fine in rhel 7.9, but the same thing giving ssh timeout error in RHEL 8.4.
But when i am creating guest vm with virt-install it is able to create a vm and i am able to see it in cockpit web ui, but when i initiate packer build then while giving ssh timeout error it is not visible in cockpit UI, so not able to see where the guest vm created get stuck.
Can anyone please help me to fix this issue
