Re: [libvirt-users] configuring a lxc guest to run 32bits from a 64bits host under libvirt-lxc
Hi again
Answering my own e-mail on a few points:
. first off, stupid me, http://libvirt.org/format.html indeed is empty and it seems to be
by design, but the subtrees are not, like e.g.
http://libvirt.org/formatdomain.html
. from this page it seems like using something like
<os>
<type arch='i686'>exe</type>
<init>/sbin/init</init>
</os>
in the guest XML config should do the trick
I need to investigate this out a little further to see if it does what I am expecting or
not

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
