Since the user appended the word "better" to the filename, this is likely a comparative statement regarding the stability or functionality of this specific build. Here is why this specific version might be considered "better":
Determining if this specific version is "better" depends on your current baseline. In the Huawei software lifecycle, is a maintenance patch (SPC) and build (B) that follows the V800R011C00 release. This public link is valid for 7 days
Perhaps the most compelling reason that qcow2 is the superior choice for network simulation is its native support for internal snapshots . This allows you to capture the complete state of a running virtual router—including its configuration, routing tables, and dynamic protocol states—in an instant. You can then return to this exact state at any time with a single command. Before implementing a complex BGP policy change, you can take a snapshot. If the change has unexpected consequences or breaks connectivity, you can instantly revert to the known-good state and try again. This rapid prototyping ability is much more cumbersome to achieve with raw disks, which require external tools (like LVM) for snapshot functionality. For network engineers who need to test and iterate quickly, snapshots are not just a convenience; they are a necessity.
The software version refers to a specific system software package and patch for the Huawei NE40E (NetEngine 40E) series routers. When paired with a .qcow2 extension, it specifically refers to a virtual disk image used for the Virtual NE40E (vNE40E) , which is typically deployed in NFV (Network Functions Virtualization) environments or for simulation and testing.
