os10-disk-1.0.0.vmdk appears to be a VMDK disk image file — likely a virtual machine disk for an OS or appliance labeled "os10" (version 1.0.0). A useful review should cover provenance, contents, usability, compatibility, size/structure, security, and recommended testing steps.
Use vzdump (Proxmox) or ghettoVCB (ESXi) to back up only changed blocks:
./ghettoVCB.sh -g os10-backup -f vms_to_backup.txt
Cause: Console type mismatch (OS10 expects a serial console by default).
Fix: Add to .vmx:
serial0.present = "TRUE"
serial0.fileType = "network"
serial0.network.endPoint = "server"
serial0.yieldOnMsrRead = "TRUE"
Option A – Mount on Linux (if it contains a supported filesystem):
# Install libguestfs-tools
sudo apt install libguestfs-tools # Debian/Ubuntu
The os10-disk-1.0.0.vmdk file represents more than just a storage component for a virtual machine. It embodies the fusion of virtualization technology and data management practices. Its naming convention and structure reflect careful planning, flexibility, and the comprehensive features offered by VMware solutions. As virtualization continues to play a critical role in IT infrastructure, understanding and managing files like os10-disk-1.0.0.vmdk becomes essential for administrators and IT professionals.
The file os10-disk-1.0.0.vmdk is a vital component of the Dell EMC SmartFabric OS10 virtual appliance, used to simulate Dell networking hardware in virtual environments like GNS3 and EVE-NG. What is os10-disk-1.0.0.vmdk?
This file serves as the base virtual hard disk drive (HDD) for the OS10 virtual machine. Unlike standard firmware images used for physical switches, this VMDK (Virtual Machine Disk) file contains the core file system architecture required to run OS10 on a hypervisor. It is typically distributed as part of a larger virtualization bundle (e.g., OS10_Virtualization_10.x.x.xV.zip) which includes two other essential files:
OS10-Installer-x.x.x.x.vmdk: Used to boot the installation process.
OS10-platform-xxxx-x.x.x.x.vmdk: Defines the specific switch hardware being simulated (e.g., S6010-ON). Role in Networking Labs
The os10-disk-1.0.0.vmdk file allows network engineers to build risk-free sandbox environments. By simulating OS10 devices, users can: os10-disk-1.0.0.vmdk
Test Configurations: Prototype scripts and network operations before deploying them on physical S-Series or Z-Series switches.
Learn Open Networking: Practice CLI commands and RESTCONF/SNMP interfaces in a virtual lab.
Demonstrate High Availability: Simulate complex technologies like Virtual Link Trunking (VLT) or Multi-chassis LAG (MLAG). Installation and Configuration
To use this file in a lab environment like EVE-NG, it must often be converted to the QCOW2 format used by QEMU.
Preparation: Create a directory for the node (e.g., /opt/unetlab/addons/qemu/dellos10-10.5.5).
Conversion: Use the following command to prepare the disk:qemu-img convert -f vmdk -O qcow2 OS10-Disk-1.0.0.vmdk sataa.qcow2.
Initial Boot: On the first boot, the appliance uses the installer disk to populate the sataa.qcow2 (formerly the 1.0.0.vmdk) with the OS10 system files.
Login: The default credentials for the virtual appliance are admin / admin. System Requirements
Running the OS10 virtual appliance requires significant resources due to its complex hardware abstraction layer: os10-disk-1
Memory: Each OS10 switch instance typically requires at least 4GB of RAM.
CPU: 4 vCPUs are generally recommended for stable performance.
Host: A 64-bit x86 CPU with at least 16GB of total system RAM is recommended for running multiple nodes.
os10-disk-1.0.0.vmdk typically refers to the virtual disk image for Dell EMC Networking OS10
, often used for running the switch operating system within virtualized lab environments like VMware ESXi
To "put together a post" about this, here is a structured guide you can use for a technical blog or internal documentation: Dell OS10 Virtual Lab Setup Guide 1. Overview
Dell EMC Networking OS10 is a Linux-based open networking operating system. The
file is the virtual disk used to boot the OS in a Virtual Machine (VM). This setup is ideal for testing configurations, automation scripts (Ansible/Python), or learning the OS10 CLI without physical hardware. 2. Prerequisites os10-disk-1.0.0.vmdk Hypervisor: VMware Workstation, ESXi, or a lab simulator like Resources (Minimum): 1 Management Interface + multiple data interfaces. 3. Deployment Steps Create the VM Shell: Create a new "Other Linux 64-bit" VM. Attach the Disk: Replace the default new hard disk with your existing os10-disk-1.0.0.vmdk In ESXi, you can use the Add Second Virtual Disk
method to ensure the disk is correctly mapped to the SCSI controller. Configure Network Adapters: Disk image content — includes:
Ensure the first adapter (Network Adapter 1) is mapped to your Management network. Subsequent adapters act as front-panel switch ports. Initial Boot:
Power on the VM. It will take several minutes to initialize the database and services. 4. Initial Configuration Access the CLI via the console connection to perform the first setup: Default Credentials: Command to enter configuration mode: configure terminal Set Management IP: interface mgmt no ip address dhcp
ip address no shutdown Use code with caution. Copied to clipboard 5. Pro-Tips for Lab Users Snapshots:
Always take a snapshot immediately after the first successful login. OS10 can be sensitive to "dirty" shutdowns.
Some OS10 images boot into ONIE (Open Network Install Environment) first. Ensure you select the "OS10 Install" or "OS10" boot option if prompted. technical forum

If you have os10-disk-1.0.0.vmdk but it’s corrupted or incomplete, use qemu-img:
qemu-img convert -f vmdk os10-disk-1.0.0.vmdk -O raw os10-disk.raw
Then reconvert with correct geometry.
Network OS appliances can be sensitive to disk latency. Optimize as follows:
