This article provides steps to install/launch a vSRX on a KVM/Ubuntu server using virt-Install

1) Upload a qcow image to the below location.

root@kvm-server:/var/lib/libvirt/images# ls -ltr
total 2798680
-rwxr-xr-x 1 root root 1019805696 Apr 14 17:03 junos-vsrx3-x86-64-24.2R2.18_vsrx2.qcow2
-rwxr-xr-x 1 root root 1028849664 Apr 14 17:03 junos-vsrx3-x86-64-24.2R2.18_vsrx1.qcow2
-rw-r--r-- 1 root root  817168384 Apr 14 17:21 junos-vsrx3-x86-64-24.2R2.18_vsrx3.qcow2

2) Use the below virt-install command to install vSRX.

virt-install --name Test5 --ram 8196 --cpu SandyBridge --vcpus=5 --arch=x86_64 --disk path=/var/lib/libvirt/images/junos-vsrx3-x86-64-24.2R2.18_vsrx5.qcow2,size=18,size=16,device=disk,bus=virtio,format=qcow2 --os-type linux --os-variant ubuntu20.04 --import --network=network:control,model=virtio  --import

--name Test5: Set the name of the vsrx

--ram 8196 : Allocates RAM. I have allocated 8GB RAM.

--vcpus 5: Assign virtual CPUs. I have assigned 5 vCPU's

--cpu SandyBridge,+vmx,-invtsc: Specify the CPU model and flags. Adapt this to match your host's capabilities and the vSRX requirements. 

--disk path=/path/to/vsrx_image.qcow2,size=16,bus=ide,format=qcow2: Specify the disk image 

Replace /path/to/vsrx_image.qcow2 with the actual path to the vSRX image. size=16 sets the disk size to 16GB.

--os-type linux: Specify the operating system type as Linux.

--os-variant rhel7: Specify the Linux variant as RHEL 7.

--import: Indicates that the VM is being created from an existing image.

--network network:control,model=virtio: Connect the VM to a virtual network. 

network:control refers to a network defined in the host.We can also assign it to a default network or any other netrworks created on the host. 

model=virtio specifies the network interface model.
