Hi Stephane, thanks for the answer. It's actually what I was trying to do. The problem I face is related to the static ip of the LXCs: here is in a bunch of words the architecture: -the physical server hosting the LXC is configured as their gateway through few bridges (one each network) and this is useful for:
1. having a single point of iptables/security implementation per network 2. the LXC gateway in the config is set as *auto* so that if an LXC is migrated towards another physical server it keeps working without any reconfig and this could be done in case of hw issues by a monitoring system (unattended) -several LXC has a static ip and I was trying to use the raw.lxc without much success Alex > > ---------- Forwarded message ---------- > From: "Stéphane Graber" <stgra...@ubuntu.com> > To: LXC users mailing-list <lxc-users@lists.linuxcontainers.org> > Cc: > Date: Thu, 16 Jun 2016 11:42:06 -0400 > Subject: Re: [lxc-users] LXC -> LXD > On Thu, Jun 16, 2016 at 05:26:10PM +0200, alex barchiesi wrote: > > Hi, I'm quite new of the list. > > Let me introduce myself quickly: I'm Alex and I recently managed the > GARR X > > Progress cloud architecture (consisting in more than 4000 cores scattered > > in 5 geo-locations). > > I'm using LXC since about 1 year and I' m seting up a multisite openstack > > liberty (that is in production for the Storage part: Swift) with the > > control plane on LXC and the compute on bare metal. > > > > I was wondering if someone smootly migrated an LXC *manually* managed > > installation to LXD and in case how :) > > > > thanks in advance for the advice > > > > Alex > > I've done that myself on a bunch of hosts. > > Typically I'd done it by creating a new LXD container, make sure that > they are similarly configured (privileged or unprivileged with same id > map), then rsync /var/lib/lxc/<container>/rootfs to > /var/lib/lxd/containers/<container>/rootfs > > > I also wrote a script in the upstream repo which uses pylxd and > python3-lxc to do the migration for you.
