This probably will be too late to help you, but, I had the same issue, and it might help someone who's seeking this, as I did a few days ago. And with the help of the folks of opensuse forums, I was able to solve it. The actions below were made using the vCenter Converter 6.
The original post with the solution is this: https://forums.opensuse.org/showthread.php/525645-vCenter-Converter-failed-code-127-RAID-and-LVM?p=2...
Just a little background, the virtualization failed at 97%, right after the grub install.
1 - Booted up the VM with the iso in Rescue mode, and logon as root(no pass)
2 - Identify the partitions and mount the root partition " / " on /mnt
3 - Mount the other existing partitions on the subsequent folders, like if /home was mounted in /dev/sda3, then, mount /dev/sda3 /mnt/home
4 - Mount the rest and chroot as follow:
mount --rbind /proc /mnt/proc
mount --rbind /sys /mnt/sys
mount --rbind /dev /mnt/dev
chroot /mnt
5 - run blkid and take note the new UUIDs of the partitions.
Output of blkid
/dev/loop0: TYPE="squashfs"
/dev/loop1: TYPE="squashfs"
/dev/loop2: TYPE="squashfs"
/dev/loop3: TYPE="squashfs"
/dev/loop4: TYPE="squashfs"

/dev/sda3: UUID="a3b48686-9add-4824-8a70-bfc5fbecb7d4" TYPE="ext4" PARTUUID="1c14d8a9-03" - usr partition

6 - Update the /etc/fstab, and, if it was created as btrfs, remove the aditional mount point lines and replace the btrfs with the TYPE detected on the blkid, which in my case was ext4:

7 - After this, I ran in order:
mkinitrd
grub2-install /dev/sda
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-install /dev/sda
- exited from chroot
umount -a
reboot
OBS: If your disk is GPT, after the grub2-install you might get a message informing that it could not install on it, yada yada yada... In this case, you must create a BIOS partition. I use cgdisk in order to do so.
#cgdisk /dev/sda
- in my case, I excluded the swap, and created a new partition, of 5MB using the code ef02, recreating the swap using the remain space:
wdprd:~ # cgdisk /dev/sda
cgdisk 0.8.8 Disk Drive: /dev/sda Size: 286676992, 136.7 GiB
Part. # Size Partition Type Partition Name
----------------------------------------------------------------
47.0 KiB free space
1 5.0 MiB BIOS boot partition bios
5 8.0 GiB Linux swap swap
2 70.0 GiB Linux filesystem usr
3 58.0 GiB Linux filesystem raiz
4 720.0 MiB Linux filesystem boot
943.5 KiB free space
At this point the machine should boot up successfully. If it stop saying that the boot failed, reboot in rescue mode again, remount everything and double check UUIDs in the fstab.
8 - You also MUST check if the the /home has being copied with full content. In one of the servers, it wasn't. So, I went back on the physical machine and:
server😕 # tar -zcvf home.tar.gz /home
copy the file to the vm and unzip it overwriting the /home
That's all folks!
