bhyve VM stopped to boot after moving virtio disks

[Wojciech Puchar]

i have bhyve VM  (linux) with 2 virtual disks.

they were backed on geli encrypted partitions on SSD

as it is rarely used VM i wanted to move it to HDD file.

i just did

dd if=/dev/partition1.eli of=file1 bs=1m
dd if=/dev/partition2.eli of=file2 bs=1m

there were no errors when doing dd

and changed /dev/partition1.eli to file1 and same with second in 
virtio-blk filename.

Everything else is unchanged.

now it doesn't boot. on UEFI virtual framebuffer i see

Boot Failed. EFI Misc Device
Boot Failed. EFI Misc Device 1
.



Could you give me any clues?
