Enabling supported nested virtualization/CPU assist exposure where required by the hypervisor and hardware would not meet the need for a hosted Type 2 hypervisor appropriate for laptop-based experiments rather than claiming bare-metal architecture.

Choosing a Type 1 bare-metal hypervisor to directly manage physical hardware and hosted VMs would not meet the need for a hosted Type 2 hypervisor appropriate for laptop-based experiments rather than claiming bare-metal architecture.

Creating separate guest VMs with allocated vCPUs, memory and virtual NICs managed by the hypervisor would not meet the need for a hosted Type 2 hypervisor appropriate for laptop-based experiments rather than claiming bare-metal architecture.

This test measures a different behavior: Inspect guest inventory and confirm two separate VM OS instances with independent virtual resources. It does not establish the target outcome. For the documented fault, the direct acceptance test is: verify the virtualization process runs on top of the user's installed host OS and creates isolated guest VMs.

That control reduces a separate risk: The solution is a hosted Type 2 hypervisor dependent on the general-purpose host OS. For the described design, the recurring risk arises from: the hypervisor is Type 2 and depends on the underlying host OS lifecycle. The specific required safeguard is: document the difference between development-only hosted virtualization and production bare-metal hosts.

That control reduces a separate risk: The environments are processes in a shared OS, not two isolated guest virtual machines. For the described design, the recurring risk arises from: the hypervisor is Type 2 and depends on the underlying host OS lifecycle. The specific required safeguard is: document the difference between development-only hosted virtualization and production bare-metal hosts.

That control reduces a separate risk: The outer hypervisor did not expose required virtualization extensions to the nested hypervisor. For the described design, the recurring risk arises from: the hypervisor is Type 2 and depends on the underlying host OS lifecycle. The specific required safeguard is: document the difference between development-only hosted virtualization and production bare-metal hosts.

Attaching the vNICs to an appropriate virtual switch/port group on the host would not create separate guest VMs with allocated vCPUs, memory and virtual NICs managed by the hypervisor.

Reserve or allocate appropriate VM memory and host capacity would not create separate guest VMs with allocated vCPUs, memory and virtual NICs managed by the hypervisor.

Enabling supported nested virtualization/CPU assist exposure where required by the hypervisor and hardware would not create separate guest VMs with allocated vCPUs, memory and virtual NICs managed by the hypervisor.

This test measures a different behavior: Capture east-west frames on the virtual switch and verify no physical-uplink transit is required for local guests. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect guest inventory and confirm two separate VM OS instances with independent virtual resources.

This test measures a different behavior: Inspect inner guest startup and exposed CPU virtualization features in the parent VM. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect guest inventory and confirm two separate VM OS instances with independent virtual resources.

This test measures a different behavior: Compare guest memory pressure and host swap/balloon activity before and after capacity adjustment. It does not establish the target outcome. For the documented fault, the direct acceptance test is: inspect guest inventory and confirm two separate VM OS instances with independent virtual resources.

That diagnosis is supported by a different symptom: Two guests in separate isolated virtual networks cannot ARP for one another despite using the same physical host. Here the recorded observation is: changes to one guest kernel unexpectedly take the other lab workload down because both tests run in one OS. The applicable cause is: the environments are processes in a shared OS, not two isolated guest virtual machines.

The applicable cause is: the environments are processes in a shared OS, not two isolated guest virtual machines.

That control reduces a separate risk: Their virtual NICs attach to different isolated virtual switches or port groups. For the described design, the recurring risk arises from: the environments are processes in a shared OS, not two isolated guest virtual machines. The specific required safeguard is: use VM snapshots and resource quotas without treating snapshots as application-consistent backups.

That control reduces a separate risk: The outer hypervisor did not expose required virtualization extensions to the nested hypervisor. For the described design, the recurring risk arises from: the environments are processes in a shared OS, not two isolated guest virtual machines. The specific required safeguard is: use VM snapshots and resource quotas without treating snapshots as application-consistent backups.

That control reduces a separate risk: The virtual machine lacks sufficient effective compute/memory resources, not packet transport reachability. For the described design, the recurring risk arises from: the environments are processes in a shared OS, not two isolated guest virtual machines. The specific required safeguard is: use VM snapshots and resource quotas without treating snapshots as application-consistent backups.

Creating separate guest VMs with allocated vCPUs, memory and virtual NICs managed by the hypervisor would not attach the vNICs to an appropriate virtual switch/port group on the host.

Aligning virtual port-group VLAN tagging and physical uplink 802.1Q trunk permitted VLANs would not attach the vNICs to an appropriate virtual switch/port group on the host.

Enabling supported virtual-switch port security or forged-transmit rejection for the guest port group would not attach the vNICs to an appropriate virtual switch/port group on the host.

This test measures a different behavior: Validate guest connectivity and port-group assignment after a test live migration. It does not establish the target outcome. For the documented fault, the direct acceptance test is: capture east-west frames on the virtual switch and verify no physical-uplink transit is required for local guests.

This test measures a different behavior: Verify tagged VLAN traffic across virtual and physical switch boundaries. It does not establish the target outcome. For the documented fault, the direct acceptance test is: capture east-west frames on the virtual switch and verify no physical-uplink transit is required for local guests.

This test measures a different behavior: Transmit a controlled spoofed-source frame and confirm the virtual switch rejects it while legitimate frames pass. It does not establish the target outcome. For the documented fault, the direct acceptance test is: capture east-west frames on the virtual switch and verify no physical-uplink transit is required for local guests.

That diagnosis is supported by a different symptom: The migrated VM lands on a host with no matching port group and loses network connectivity. Here the recorded observation is: two guests in separate isolated virtual networks cannot ARP for one another despite using the same physical host. The applicable cause is: their virtual NICs attach to different isolated virtual switches or port groups.

That diagnosis is supported by a different symptom: A compromised VM forges another tenant's MAC and sends frames through its vNIC unrestricted. Here the recorded observation is: two guests in separate isolated virtual networks cannot ARP for one another despite using the same physical host. The applicable cause is: their virtual NICs attach to different isolated virtual switches or port groups.
