I'm confused as to why you reported this bug against lxc in ubuntu. Were you running vagrant+virtualbox inside an ubuntu lxc container?

Nope sorry. that was my first bug request so i probably does't understand how it works

Today i found a new version v20160714.0.0 the problem remains the same. load is tooooooo slow.

ok, it seems i found a problem.
/etc/default/grub.d/50-cloudimg-settings.cfg:GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS0"

that line. it brokes everyting. withpout it ubuntu loads just like normal linux. for about 10 seconds

I can confirm this bug and looks like it's duplicate of #1567265.
