Routers with more than three interfaces? Not that uncommon! It might be handy, if several devices are needed with more than three interfaces, to: not: deploy the devices with three interfaces first add the needed number of interfaces to the routers attache tne new interfaces to the correct vSphere-Portgroup but instead: create an OVA-Template with the correct number of interfaces (one time) deploy the routers and attach them during deployment to their portgroup So using vNIC Hot-Add might be not the favourite way to work. Common OVF Tool COT lets you to deploy Cisco CSR1000v routers by easy to use (linux-)commands. (Common OVF Tool (COT)Read More →

My apprehension – a weird nightmare of having to shutdown the router, add the nic and boot the router again – proved wrong. vNIC Hot-Add is supported for VMware ESXi, Citrix XenServer and KVM Not for Hyper-V, Azure, AWS today. Cisco: Virtual Machine Requirements …up to 10 vNICs for ESXi btw.

Sometimes I need a lightweight straight-forward toolset to provision, modify or delete vSphere-Objects. Installation was a nightmare in former times, but vSphere CLI Release 6.5 works with Ubuntu server 16.04.3 LTS „out of the box“. And – it’s compatible with ESXi 6.0 hosts. (don’t waste time trying to install vSphere CLI Release 6.0 on a current Linux Server) Consider the docs: vSphere CLI Documentation VMware [Code] vSphere-CLI 6.5 Download the 64-bit Archive Use the vmware-search or Google… „Download VMware vSphere Command Line Interface 6.5“ might be a promising query. I downloaded VMware-vSphere-CLI-6.5.0-4566394.x86_64.tar.gz using my Windows Machine. Transfer the Archive to the Linux-VM using SCP SinceRead More →
