When performing an Instant VM Recovery from VMware backup of RHEL VM to Nutanix AHV. The RHEL VM failed to boot up. Please follow the steps to install the VirtIO drivers into the RHEL VM. Not all Linux VMs require this process, in most cases this isn't necessary. 

 

  1. Initiated IVMR from VMware Backup of RHEL VM to AHV.

2. Noticed the RHEL VM did not boot up see screen below.

  1. I went into RHEL VM and followed the steps in this Nutanix KB article link below to add VirtIO drivers. I then rebooted the VM. I took another incremental backup. Caution, please make sure you have a good backup before proceeding.

    root@linux# dracut --add-drivers "virtio_scsi virtio_pci" -f -v /boot/initramfs-`uname -r`.img `uname -r`
  1. I reran the Instant VM Recovery with the latest incremental point and the VM booted. I then migrated VM over to production. It was completed successfully.

  1. I rebooted VM to make sure it would boot into the normal process.

  1. The login screen appeared.

This is a great example of why testing your backups with a restore is so important!

Could not agree more as I have seen some questions recently about migrating Linux to other hypervisors and then they don’t boot properly.

@Tommy O'Shea Yes. Backup is easy and restore is critical😀.

@Chris.Childerhose if VMs fail to boot in Nutanix you will need to install VirtIO drivers😁
