Verifying the Cisco CSR 1000v Hardware and VM Requirements
To help troubleshoot issues with the Cisco CSR 1000v, make sure that the router is installed on supported
hardware and that the VM requirements are being met:
• Verify that the server hardware is supported by the hypervisor vendor.
If using VMware, verify that the server is listed on the VMware Hardware Compatibility List. See the
VMware documentation for more information.
• Verify that the I/O devices (for example, FC, iSCSI, SAS) being used are supported by the VM vendor.
• Verify that sufficient RAM is allocated on the server for the VMs and the hypervisor host.
If using VMware, make sure the server has enough RAM to support both the VMs and VMware ESXi.
• Verify the hypervisor version is supported by the Cisco CSR 1000v.
• Verify that the correct VM settings for the amount of memory, number of CPUs, and disk size are
configured.
• Verify that the vNICs are configured using a supported network driver. See
Installation Overview

• Verify that there is an active and unexpired license installed on the VM.
Enter the

command. The License State should be shown as “Active, In Use”.
• Verify that the vNIC for the VMs are connected to the correct physical NIC, or to the proper vSwitch.
