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.
