How can I migrate my legacy Windows guests from VMWare to Qemu/KVM
I am setting up my new laptop and would like to move in three legacy Windows guests from the old laptop (also running Arch with VMWare Workstation where two of the Windows guests reside).
On the new machine, I don't want to install VMWare Workstation and would like to migrate to KVM instead (my old Arch install has already been set up as guest and works better than on the old laptop). However, everything I tried to convert Windows guests and make them working in KVM invariably fails. From VMWare Workstation I tried cloning vmdk, exporting to ovf, converting with vCenter Converter Standalone, then converting with qemu-img. The resulting qcow2 or raw images won't boot (with sata/scsi/virtio, with or without VMWare tools in the converted vmdk). I am looking at a black screen with "Booting from hard drive" message.
I am wondering if it works at all. Seems as though I will have to say goodbye to my old machines and install new Windows under KVM. Or is there a way out?
Any help would be very much appreciated.
Here is the output of virt-rescue on vmdk disks (qemu-img doesn't complain when converting but virt-rescue indicates there are issues with vmdk images):

Re: How can I migrate my legacy Windows guests from VMWare to Qemu/KVM
I had some ideas, but you have already tried those .
Re-reading your post I noticed you don't mention what methods you tried to start the converted guests .
Were all your efforts with libvirt clients like virt-manager and virsh ?
If yes, try starting the guests with qemu from commandline .
That should help to narrow down where things go south.
Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: How can I migrate my legacy Windows guests from VMWare to Qemu/KVM
I should have mentioned that I tried every tool available to boot the images. (I actually started with qemu). One other thing I didn't mention was that I also tried using MS tool, disk2vhd, to convert the machines into images, with the same level of success.
Eventually, I found the problem, but hadn't been able to fix it. I tried booting from a windows installation iso that I attached as a cdrom and tinkering with MS recovery tools on raw images. Turns out all the images have broken boot partition (which, surprisingly, doesn't prevent them from booting with no problem whatsoever from within VMWare!). So, I used MS recovery tools to fix them. The problem is that for some inexplicable reason my recovery does not persist on the images: I fix the boot partition, exit, boot from HD, it doesn't boot, I boot from cdrom again and it turns out the boot partition is broken again, the same way it was before I fixed it! There's no way you can dd the fixed partition from within the MS recovery tools, alas.
Ultimately, I washed hands. Now trying to bring in old tools from the VMs to the freshly installed VM on my new laptop. The solution is not without its perks in that I have to leave behind some rarely used stuff, resulting in a leaner system. But I still feel pretty much beaten and don't feel like marking the thread 'solved'.
It's one of those things about MS products that pushed me towards using Linux almost 20 years ago. For which I am grateful to MS and to the world of commercial software in general.

Did you do the required step to load the virtio drivers during install for a Windows install with QEMU? You should be able to do a new Windows install with QEMU.
I wonder if the missing virtio driver is the problem with the migrated images as well? The Wiki has a step on how to add those to existing VMs.

That's exactly what I ended up doing. No problem with that. The reason I used the installation ISO, though, was not to install a new VM, but to get access to Windows repair tools available on the ISO and to use those tools to try and repair the raw image of my old, pre-existing VM, exported from VMWare Workstation.

If you read the guidance under the link, it says in pertinent part:
Run the original Windows guest (with the boot disk still in IDE mode) with the fake disk (in virtio mode) and a CD-ROM with the driver.
....
Windows will detect the fake disk and look for a suitable driver.
I think it is pretty clear that by "original Windows guest" they mean the Windows guest that has already been running under KVM but was not using the virtio drivers, and not a raw or vmdk image that I was trying to bring into KVM. You see, that was my problem: it just didn't boot. So, it wasn't able to "detect the fake disk and look for a suitable driver".
And maybe for the better. I am now getting some comfort in getting rid of all the bloat of the old machine as I gradually transfer legacy apps from it to the newly-installed VM.
