Windows host p2v. Image size issue

Hello,

Windows host to Opennebula (some kind of p2v) convertion.
Disk image of drive C has been created with Disk2vhd tool:

$ du -sh WINHOST.VHDX
48G     WINHOST.VHDX

Image has been converted to qcow2 format:

$ qemu-img convert -p -f vhdx -O qcow2 WINHOST.VHDX winhost.qcow2
$ du -sh winhost.qcow2
48G     winhost.qcow2

Converted image has been uploaded to opennebula datastore:

$ oneimage create --name winhost --path winhost.qcow2 --driver qcow2 --datastore default

And Opennebula see it as 930GB:

$ oneimage show 95
IMAGE 95 INFORMATION

How could it be?

@barte1by thanks for the command.

Drive C physical size is 195.31GB (Base, NTFS, Free space – 143GB).
Why virtual size is so huge?
Seems something wrong with disk2vhd tool.

Get-VHD “{disk}.vhdx” there are lines ‘size’ and ‘minumsize’

Get-VHS only works with enabled hyper-v feature on the host.
And AFAIK this PS cmdlet unavailable under WS2K8.
