Thanks, I'll look into VDDK. Attached a screenshot of the disk from the VM's perspective. C:\windows\system32\cmd.exe definitely exists (confirmed it). It's Windows 10 (Microsoft Windows 10 x64 from VMware's point of view) - build 2004 19041.985. Maybe the file transfer had an issue (running ovftool), since the resulting OVA file was 128 GB, while the VM is 450 GB thick provisioned with more than 128 GB in use. What would the expected OVA size be here? ovftool did say that the transfer completed successfully and I've run it twice where it stopped at 128 GB both times.

It looks like I've finally gotten some imports to work. Not with the 450 GB VM yet, but with some other VMs from the same VMware environment, which should have a similar config. The steps for me were: # export LIBGUESTFS_BACKEND=direct (not too sure if this is required) # ovftool vi://<vcenter_path_to_vm> /<some_local_directory>/<vm>.ova # chown 36:36 <vm>.ova and then importing via the oVirt GUI by setting Source: Virtual Appliance (OVA) and specifying the path to the ova on the host. The VM usually wouldn't boot right away (different errors for 2 different attempts), but after making some edit via oVirt and reverting, it would boot. I'm also not using virtio and don't have virtio drivers for Windows. Maybe that's something worth looking into though.

Unfortunately this issue (or something similar) has resurfaced with another VM. Several VMs have worked. This Windows VM is failing to import, either via the oVirt GUI or running virt-v2v directly. Attached the log and here is the snippet that seems relevant to me. Rich, any suggestions here? Thanks! - Alan inspect_os: fses: fs: /dev/sda1 (ntfs) role: other fs: /dev/sda2 (ntfs) role: other inspect_get_roots: roots: guestfsd: => inspect_os (0x1e0) took 1.07 secs libguestfs: trace: v2v: inspect_os = [] virt-v2v: error: inspection could not detect the source guest (or physical machine). Assuming that you are running virt-v2v/virt-p2v on a source which is supported (and not, for example, a blank disk), then this should not happen. No root device found in this operating system image. Btw, I have to select Other OS in the oVirt GUI because when selecting Windows it complains about "Cannot import VM. Invalid time zone for given OS type" "Attribute: vm.vmStatic" On Sat, May 29, 2021 at 8:40 PM Alan Daniels <alan at softdrive.co> wrote:> It looks like I've finally gotten some imports to work.
