Known Issues and Troubleshooting

RHEL 7.x VM might not start after conversion to VMware

Symptom

After you convert a RHEL 7.x virtual machine from Hyper-V to VMware, the VM might fail to boot.

Cause

Drivers that are loaded in initrd for Hyper-V Linux VMs do not work after conversion to VMware. Required drivers need to be loaded into default initrd after conversion.

Resolution

  1. Boot the converted VM using the Rescue Mode option.

    The initial RAM file system for Rescue Mode includes the IDE driver.

  2. Make a backup of the initial RAM disk (initrd).
  3. Run the following command to generate a new initial RAM file system for the converted VM:

    dracut -f

    This command loads required modules that are needed to access the root file system.

  4. Reboot the virtual machine using the default boot option.
