Moreover, in OpenVZ live migration allows to migrate 32bit VPSs
between i686 and x86-64 Linux machines.

How would that work when x86-64 32bit programs have 4GB of address
space and native on i386 programs only 3GB?
we limit address space of i386 apps on x86-64 to 3GB due to compatibility issues - some applications don't work with not 3:1 GB VM split.

On the other hand if you need 4GB addr space for user you can use 4GB x8664 and 4gb split on i386.

Thanks,
Kirill
