qemu-img can convert many formats. Here is an example of how to convert different images to different formats for QEMU-KVM The example above converts a raw windows2019.img file from QEMU to a Virtualbox .vdi qemu-img convert -f raw -Ovdi windows2019.img windows2019.vdi -f raw = this means the format of the source image (instead of raw it could be vdi, vmdi, qcow2 etc..)........

The example below converts youvm.img into a vdi. The -O vdi specifies the new format will be vdi but you can use any other valid formats/vice versa. qemu-img convert yourvm.img -O vdi yourvm.vdi This is very handy for those who need to switch between virtualization technologies.........

Go into the directory for your Virtual Machine and delete all ".lck" directories. rm -rf *.lck After that your server should boot.........

I wanted to Import/Use a .vmdk hard disk image file from VMWare. Generally you can just "point" VirtualBox to it and use it and it will work but I found an exception. One of my Centos 4.4 x64 images wouldn't boot. I had two copies, an older one and the newer one. The older one booted as normal (once I changed the VirtualBox driver to IDE from SATA). The newer one stopped at the "GRUB loading" message no matter what I tried. As far as........

The last transfer I was able to do was 16.77GB according to rsync's output and it worked fine. 16.77G 100% 10.66MB/s 0:25:00 (xfer#17484, to-check=234753/256249) But on a file over 17GB (gigs) it stalls. Trust me, it really is stalled, it's been about 8 hours with no progression from that point for some reason. 17.24G 54% 10.65MB/s 0:22:07........
