[libvirt-users] configuring a lxc guest to run 32bits from a 64bits host under libvirt-lxc

[Thierry Parmentelat]

Hi there
I have a couple of newbie questions concerning running a 32bits guest in a 64bits host using libvirt - lxc; I’m running libvirt-1.2.5 on fedora18 and fedora20

(a) is this supported at all, and 
(b) if so how do I configure this for a given guest ?

guessing from the mere existence of http://www.redhat.com/archives/libvir-list/2011-February/msg01040.html
I would think the answer to (a) is yes; anybody cares to confirm ?

As far as (b), I would expect some flag could be set in the XML description of my guest so that libvirt can perform the proper syscall to personality() at the right point in the process hierarchy..
However I have not been able to spot this in the documentation so far, but OTOH the page on the XML configuration here
http://libvirt.org/format.html
appears to be empty so this might be a temporary hiccup ?

in any case, any hint or insight on this matter would be much appreciated — Thierry
