broken image after installworld/installkernel

[Sergey Matveychuk]

Hi.

My VM image has broken twice after I did installworld/installkernel 
inside VM.

First time I installed FreeBSD-10 from this ISO-image: 
ftp://ftp.ru.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/10.0/FreeBSD-10.0-RC4-amd64-disc1.iso

It worked well, but after I did 'svn co' buildworld/buildkernel 
installworld/installkernel kernel even did not boot.

Second time I install FreeBSD-10 from the same ISO and after the same 
action I have:
