I am researching the installation log of stand-alone foundation. I do not understand the background schema and theory of hypervisor and CVM installation. Could somebody please explain how hypervisor and CVM installer work?

Hi Hienle,

Thanks very much for the reply.

  1. Is foundation applet able to discover nodes which are bare metal?
  2. The hypervisor is imaged by using a VM which resides on the hypervisor drive. Correct?
  3. For the CVM imaging process, I only found many packages are decompressed in SSD. How CVM OS is installed?
Thanks!
  1. Foundation Applet will be able to discover nodes if CVM are running on those node via Ipv6. With that said, with bare-metal node (node that does not have CVM running), you cannot use Foundation Applet to do that
  2. There is a VM booted from a CentOS live cd (Phoenix) to control the hypervisor and AOS installation
  3. I am not sure about this but IMO, CVM image file is just kind of an OVF file that need to be mounted, package extracted, installed, made to be run and configured follow the hypervisor type

Hi,

Really appreciate your response. The video shares knowledge about Nutanix Architecture. But what I was consulting is how nutanix installer works in background, like how hypervisor is installed and how CVM OS and nutanix software are installed.

Thanks,

Not just in detail but over all, Foundation installer would work in step by step as below:
  1. Detect the CVM and IPMI info by Ipv6
  2. Resolve the IPMI Mac address to IPv6 and then connect to it to configure Ipv4
  3. Remote control the IPMI via IPv4 to mount the hypervisor and CVM installer iso image
  4. Install the Hypervisor to Satadom/M2 drive by using hypervisor iso image
  5. Install the CVM to SSD by using AOS file
  6. Configure networking and run the first boot script
  7. Reboot CVM and host to complete the installation
