Verifying that Required Hyper-V drivers Are Installed on the Source VM

Before you perform a backup for a Linux source VM that runs Red Hat, verify that required Hyper-V drivers are installed on the source VM. Those drivers must be present on the source VM backup in order to boot the VM after conversion.

1. Enable Changed Block Tracking (CBT) for the source VM.

2. Take a snapshot of the source VM.

3. Run the following command to modify the boot image:

   sudo dracut -f -v -N

4. Run the following command to verify that Hyper-V drivers are present in the boot image:

   lsinitrd | grep hv

5. Verify that no dracut conf files (for example, /usr/lib/dracut/dracut.conf.d/01-dist.conf) contain the following line:

   hostonly="yes"

6. Run a new backup to use for the conversion.
