Jails: VIMAGE option unavailable (greyed)

[shpokas]

Hi there,
any idea why VIMAGE option is unavailable in my FreeNAS installation?
I have another test installation and all is fine there.
But this one was migrated and upgraded from 32-bit to 64-bit.

Note, promiscuous mode is enabled on interface (according to manual) even it seems not to be required for my test installation.

[root@vfs] ~# ifconfig bridge0

Answering myself :/
Quite accidentally I found that all jail templates are listed as x86, 32-bit that is.
As soon as I changed them to 64-bit, VIMAGE option became available.
