You might encounter network issues if:
- A network adapter was not attached to the virtual machine at the time of backup
- Multiple network adapters were attached to the virtual machine at the time of backup
- Network adapter attached to the virtual machine runs into issues due to its driver
- Network adapter that Phoenix attaches is incompatible with the guest operating system
- The network adapter was not attached to the virtual machine after restore
Resolution
After restoring the virtual machine:
- If a network adapter was not attached to the virtual machine at the time of backup, Phoenix will attach the VMXNET3 or VMXNET2 type adapter and restore the virtual machine with the selected network setting. However, the VMXNET3 or VMXNET2 adapter the Phoenix will attach will require appropriate drivers. To resolve the issue, install VMware tools and the adapter driver on the guest operating system. Or, you can change the network adapter from the vCenter web client UI.
- If multiple adapters were attached to the virtual machine at the time of backup, the restored virtual machine can experience network issues because you can select only one network setting at the time of restore. To resolve this issue, specify appropriate network setting for each adapter after restore.
- If the Phoenix attached network adapter is incompatible with the guest operating system, the vCenter web client displays a warning. To resolve the issue, select an appropriate network adapter for the virtual machine from the web client UI.
- If Phoenix backup proxy runs into issues with attaching the network adapter at the time of restore, it skips attaching the network adapter. To resolve the issue, after the virtual machine is restored, select and attach the appropriate network adapter to the virtual machine from the web client UI.
