Make a copy of your hard drive with the command:
dd if=/dev/sda of=/mnt/backup/sda.img bs=8M conv=sync,noerror
if=/dev/sda - copy the entire sda hard drive;
of=/mnt/backup/sda.img - copy to /mnt/backup/sda.img, where the /mnt/backup directory is the mount point of the disk that will contain the image;
bs=8M - set the hard disk cache size to speed up the copy process (otherwise the data will be reset in small portions of 512 bytes);
conv=sync,noerror - indicate dd to copy by bit type regardless of read errors.
Convert the resulting image to vmdk using QEMU (see article).
Next, you can use VMware Workstation Pro to create a machine from the converted disc and export it to OVF (see article)
