Migration Vmware to Hyper-V

[Lehn_MR]

Hello,

I have a problem during the boot with a VM after converting it from Vmware to Hyper-V.
The machine is a Red-Hat 7.5 and this following erreurs display :

Code: Select all

/dev/mapper/rhel-root does not exist
/dev/rhel/root does not exist
/dev/rhel/swap does not exist

I have already tried to regenerate the dracut to solve the problem but it doesn't change anything...
Below the command that i've tried :

Code: Select all

 dracut -f -v --regenerate-all 

I've tried to add the following parameter in the /etc/dracut.conf :

Code: Select all

add_drivers+=" hid_hyperv hv_utils hv_vmbus hv_storvsc hv_netsvc"

But it doesn't change anything too

The rescue mode start without any problem.

Can you help me to solve this problem please?

Welcome to StarWind Forum. Can you please convert an individual disk and recreate the VM using that disk?
Use repair mode checkbox if possible.

Hello,

Thanks for your answer.
I tried your method but I had the same result during the VM boot.
During the conversion, I checked the Repair mode but it didn't work and returned an error.

Do you have any others ideas ?

Hi,

You are always welcome!
Do you have VMware tools installed into that VM?

Hello

Yes, VMware Tools is install into the VM.

Thanks for your feedback.
Can you try uninstalling them prior to conversion?
The error you point out seems to be some sort of a driver mismatch.
As a last resort, you can try converting the VM to OVF and moving it to the destination.

Hello,

I tried too but it did'nt work too, the same erreur appear during the boot.
To solve my problem, I reinstall from scratch the VM directly in the HyperV environment and everything work now.

Thanks again for your help
