When we powered off VMs through vCenter prior to exporting/importing, sometimes it would complain about failing to mount /dev/sda2: Failed to mount '/dev/sda2': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option. ocaml_exn: 'mount' raised 'Failure' exception guestfsd: error: mount exited with status 14: The disk contains an unclean file system (0, 0). Metadata kept in Windows cache, refused to mount. Failed to mount '/dev/sda2': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option. guestfsd: => mount (0x1) took 0.03 secs libguestfs: trace: v2v: mount = -1 (error) virt-v2v: error: unable to mount the disk image for writing. This has probably happened because Windows Hibernation or Fast Restart is being used in this guest. You have to disable this (in the guest) in order to use virt-v2v. After this, we started always shutting off the VMs inside the Guest OS via shift-shutdown. This resolved the error above. However, the guests do not support Hibernate / Fast Shutdown: PS C:\WINDOWS\system32> powercfg /a The following sleep states are not available on this system: Standby (S1) An internal system component has disabled this standby state. Graphics Standby (S2) The system firmware does not support this standby state. An internal system component has disabled this standby state. Graphics Standby (S3) The system firmware does not support this standby state. An internal system component has disabled this standby state. Graphics Hibernate The system firmware does not support hibernation. Standby (S0 Low Power Idle) The system firmware does not support this standby state. Hybrid Sleep Standby (S3) is not available. Hibernation is not available. Fast Startup Hibernation is not available. Thanks! - Alan On Fri, Jun 18, 2021 at 6:27 AM Richard W.M.

I didn't try, but as far as I know the instructions for disabling fast startup are these ones: https://libguestfs.org/virt-v2v.1.html#windows-8-fast-startup-is-incompat... > Could you let me know how to upgrade to a later version? I don't think Oracle ships any newer version, but in Fedora 34 we have the latest virt-v2v packages.

So to be totally clear, are you using Fedora 34 (or a recent upstream version of virt-v2v), and what is the error message with that version?

You mentioned that it still fails on latest though. Here we'll help you use the upstream version, or for help with the old version contact Oracle support. For the upstream (or near-upstream) version I'd suggest installing a Fedora 34 virtual machine and using that. If you have trouble on Fedora 34, post the virt-v2v -v -x log with the failure.
