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 procedure (otherwise data will be reset in small portions of 512 bytes);
conv=sync,noerror - indicate dd to copy by bit type with no regard for reading errors.
Convert the resulting image to vmdk using QEMU (see article).
Next, you can use VMware Workstation Pro to create a machine with the disk obtained after conversion and export it to OVF (see article)
