Re: Hyper-V to KVM | v2v

What step I did was:
1. Used qemu-img to convert the vhdx to raw img 2. Created a blank disk and copied my converted disk to same location. 3. Renamed the converted drive with the name of blank disk. 4. Created a VM and attached my converted disk to VM.
Error: No bootable disk found
But when I attack this disk to another running VM, there I can see the data. But noting booting as bootable.

One question, once disk is converted to KVM format.
What is the way to use that drive and run a VM from it within Ovirt environment.

Have you tried to power up and fully shutdown the VM ?

Hello,
I am trying to convert a Hyper-V guest VM to run on KVM using virt-v2v utility.
Getting below error:

Any suggestions how to solve this.
Thanks

Hi Vijay Based on your initial post about using virt-v2v I don't know how intelligent virt-v2v is in knowing and converting the VM machine type. However the boot issue could be related to Hyper-V defaulting to "Gen 2" VMs which are all UEFI based. Hence your current VMs should have a FAT32 partition with an EFI loader. oVirt by default emulates 440FX Chipset and a legacy SeaBIOS. Only so-called Gen 1 VMs were emulating a legacy BIOS on the Hyper-V side. You should be able to check VM generation on Hyper-V using this PowerShell command: Get-VM | Format-List Name,Generation If it is a Gen 2 VM, starting with oVirt 4.3 you could try booting a converted disk on a VM with Q35 and OVMF (UEFI). Keep in mind that 4.3 still has some rough edges in that area. For example all settings written to the UEFI NVRAM get lost when turning off and on the VM in oVirt. This affects the bootloader entries in OVMF that an OS installer eventually created during setup. Thus the OVMF only ever looks for an EFI loader bootloader in the path boot/efi/bootx64.efi in that FAT32 partition. However if that path is not present, OVMF should open the "BIOS settings" and you should be able to "boot from file" and then select the .efi file if the given operating system and make an attempt at booting the guest OS. The current workaround that seems to work now is to copy the OS's .efi loader to the default location OVMF is looking for a bootloader as described here: https://bugzilla.redhat.com/show_bug.cgi?id=1727987 Regards, Mathieu
Hi. Although if I add this converted disk as second disk..I could see the data there. But not booting as single disk..as windows 2016 OS data is kept and have to deliver to one of my client. Bit of stuck here. Thanks On Sun, 8 Dec 2019 at 11:46 AM, Mathieu Simon <mathieu.simon@gymneufeld.ch> wrote:

Hi Vijay
Although if I add this converted disk as second disk..I could see the data there. Yes, that is pretty much expected.
But not booting as single disk..as windows 2016 OS data is kept and have to deliver to one of my client. Bit of stuck here. Maybe I wasn't clear: You first need to check whether your Hyper-V VM in question is a Gen 2 UEFI-based VM or a legacy BIOS-based Gen 1 VM. (It's quite likely Gen 2 since this has been the default since Hyper-V on Server 2012 R2) This defines the way on how the destination VM on the oVirt side needs to be configured.
Once that is identified, try the according machine type on the oVirt side there that converted disk is attached to: - Hyper-V Gen 1 => oVirt 440FX + SeaBIOS (default in oVirt as of writing) - Hyper-V Gen 2 => oVirt Q35 + OVMF As written previously: There are still plenty of limitations in the UEFI guest support and they sometimes need workarounds until hopefully oVirt 4.4 closes most of these gaps.
