Nxosv9k-7.0.3.i7.4.qcow2 Plugin -

If you cannot find a ready-made plugin, create a custom wrapper script that auto-generates a libvirt domain XML for nxosv9k-7.0.3.i7.4.qcow2. This “poor man’s plugin” ensures consistent deployment.

Example XML snippet (critical for NXOSv9k):

<domain type='kvm'>
  <name>nxosv9k-test</name>
  <memory unit='GB'>4</memory>
  <vcpu>2</vcpu>
  <os>
    <type arch='x86_64' machine='pc-q35-2.9'>hvm</type>
    <boot dev='hd'/>
  </os>
  <devices>
    <serial type='pty'>
      <target port='0'/>
    </serial>
    <console type='pty'>
      <target type='serial' port='0'/>
    </console>
    <interface type='bridge'>
      <source bridge='br0'/>
      <model type='virtio'/>
    </interface>
  </devices>
</domain>

Save this as nxosv9k-plugin.xml and deploy with: nxosv9k-7.0.3.i7.4.qcow2 plugin

virt-install --import --name nxos-test --ram 4096 --vcpu 2 \
  --disk path=/images/nxosv9k-7.0.3.i7.4.qcow2,format=qcow2 \
  --os-variant generic --serial pty --console pty,target_type=serial \
  --network bridge=br0,model=virtio

  • Boot time: NX-OSv images take 3–5 minutes to fully boot. Be patient.

  • Credentials: Common defaults for Cisco images: If you cannot find a ready-made plugin, create

  • After vagrant up:

    vagrant ssh
# or
vagrant ssh-config   # get SSH details

  • If you need raw libvirt domain XML instead of Vagrant, here’s a minimal virsh definition snippet: Save this as nxosv9k-plugin

    • <domain type='kvm'>
  <name>nxosv9k</name>
