Hi all,

I'm currently attempting to get OpenVZ up and running on an ARM device (the Raspberry Pi), but am encountering a number of difficulties.

I started by downloading and attempting to compile the current version of the kernel (vzkernel-2.6.32-042stab057.1) but encountered a number of errors (missing arguments, duplicated declarations etc) which lead me to think the ARM specific sections are not currently maintained. While investigating this I also found a post stating that live migration (which we are particularly interested in) is only supported on x86/x86-64.

So therefore I would ask:

a) Does the current version of the kernel actually support ARM? / Were any previous kernel versions known to support ARM ?

b) What level of effort (roughly) would be needed to enable live migration support on ARM?

Cheers,
Robbie Simpson

It is working on ARM for some older kernel versions:

I would ask what is the oldest kernel version pretty close to 2.6.32
that would compile for the Rpi?

"In July 2005, after several failed attempts to legalise software
patents in Europe, the patent establishment changed its strategy.
Instead of explicitly seeking to sanction the patentability of
software, they are now seeking to create a central European patent
court, which would establish and enforce patentability rules in their
favor, without any possibility of correction by competing courts or
democratically elected legislators."
