[Qemu-discuss] qemu-img convert

[Upendra Sahu]

Hi,

 

When I am using to convert VMDK to VHD (format vpc),

 

1.       Why its creating new file with new format, can I change original file itself to new format, if its creating new file it means its copying all the block of disk image and also changing the metadata, headers?

2.       When I converting 8GB vmdk to vhd (format vpc) I see converted image size as around 4GB, how its changing the size.

3.       In conversion process, does qemu-img removes free sectors and defragment the virtual disk? Can I disable that and just create new metadata for output format image to reduce the conversion time?

 

Thanks & Regards,

Upendra
