Is it possible to create a cluster using x86 and x64 architecture ?

[lince]

Hello there,

There is not much to explain, is it possible to have a cluster with servers that are 32 bits and servers that are 64 bits ?

At the moment I'm using both kvm and openvz with proxmox 3.4.

Thanks.

Hi,
you need 64bit server! Without hardware virtualisation you can run OpenVZ only (I assume LXC also).

Years ago, there was an hack to run pve on 32bit...

But in this days it should be cheaper to run an actual 64bit server than an older one (powerconsumption against cpu/IO-power).

Thanks for the quick reply

I think I made a mistake checking my architecture, uname -a returns i686 but I think I have a x64 laptop because the cpu does have the flags "vmx" and "lm". I also booted with a proxmox usb and uname -a returns x86_64.


So after all it looks like uname -a and getconf are not to be trusted when you want to know your cpu's architecture:

# uname -a
i686

# getconf LONG_BIT
32

I guess this might be because the debian installed is 32 bits. The same commands in proxmox return:

# uname -a
x86_64

# getconf LONG_BIT
64

Next time I will just check the cpu flags
