I successfully ported pve-cluster on a Raspberry Pi from the first (!) generation.
I have now packages for pve-common, pve-cluster, pve-access control.

Created a cluster on it and tested the FS a little. I'll include it in a real test setup.

I would not recommend the first generation for anything else than testing, its - not to powerful - single core is a limitation which can lead to starvation of corosync/pmxcfs, also we are using 64 bit stuff heavily on a 32 bit platform, each instruction takes almost double the cycles then on the ARMv8 from the Raspberry Pi 3.

Nonetheless initial POC was made, the packages I build are for armhf architecture while the Pi3 you get is aarch64 so they won't be of use.
But an RasPi3 is also underway to me and I'll continue with that.

@Wolfgang: the system call numbers are OK, it seems they are independent and a "compat_sys_call_table" provides the number to function mapping for each arch.

cheers,
Thomas
