Hello,
I create simple script based on virt-resize as example, and I want to
copy freebsd installation between vm's
http://pastebin.com/ZK7Bg6FQ
At boot I receive error "Missing operating system".
There is first 1M of images:
http://i.libc6.org/media/opensource/template.img
http://i.libc6.org/media/opensource/cloned.img
Images is similar except partition table on 0x1BE address
It fails to boot only with freebsd, debian and centos clones fine.
For example
http://i.libc6.org/media/opensource/debian_temlate.img
http://i.libc6.org/media/opensource/debian_cloned.img

This error "Missing operating system" comes from the boot sector; you
can actually look at the boot sector very easily by doing:
objdump -D -b binary -m i8086 cloned.img
A while back I looked into one of these boot sector disassemblies and
found that the "Missing operating system" error occurs for quite a
specific reason, although I can't quite recall what that was now.
