Kelven,
This is what I get in the LXC host agent log when I try to check the
console from CS:

As long as the container VNC console is reachable from console proxy
agent, I don't see a technical issue here. Need some log details to
understand the situation. For example, what information does LXC
hypervisor resource agent returns on GetVncPort command?

Thanks! Is the console proxy issue will be fixed at some point in the
future or this won't be possible?

Yes, the console proxy VM is unable to connect to the LXC console. Use
virsh to connect from the host.

Ok, I followed Chiradeep's comment here, and it now works fine. I
have CentOS 6 containers running.
My only other questions would be:
- Is it normal that the console proxy VM cannot proxy the
container's console?
- How can I access the container console from the host? (I am on
CentOS) I can ssh to the container tho.
Thanks!

So here's what should work
Create zone
Add a KVM cluster -> add a KVM host -> wait for systemvms to

If it's designed to do that, then something is wrong with

with it.
When I was trying to get the KVM images to work, they were
starting,
getting IPs, but then something was killing the VM. I
though for
sometime that libvirt was the issue, so I tried Ubuntu
13.10, 12.04 and
CentOS with the same results. I then switched the
hypervisor type in CS
>from LXC to KVM (rebuilt the zone), keep the same settings on
my host,
and the System VMs are running fine since then.
Anyone have time to help me troubleshoot? I mean, this is
not a blocker,
but I can't get standalone LXC cluster to work...

As it was originally discussed and implemented, the
decision was to
use KVM as the system VM for LXC clusters instead of
creating an LXC
system VM. A zone with only LXC clusters will deploy a
KVM system VM
on a host running an LXC agent. Behind the scenes,
this is possible
because both KVM and LXC agents use libvirt for
provisioning (and that
the setup of an LXC agent is almost identical to KVM
and perfectly
capable of running KVM VMs).

If this is the case, then you should remove the
ability to create
LXC zones or clarify the documentation about that.
According to the wiki page:
Each of the different hypervisors currently have
their own System
VMs. These system VM images are used to run a
console proxy,
secondary storage, and router VMs.
We discussed the possibility of creating System
VMs for LXC. There
was concern with the complexity and potential
issues involving
iptables for the router inside an LXC container.
As an
intermediate solution we are going to use KVM
System VMs inside
the LXC Cluster.
So we need a KVM cluster to run the VMs? (Added

As far as I understand, in an LXC scenario,
the system vms are

run on real hypervisors.
You can always use the QuickCloud way to not
use system vms at
all.

I am trying to get the SSVM/CPVM to run
on a LXC host. The
SSVM/CPVM
starts, get IPs, but then CloudStack kill
them for some
reason. Yes, I
use the 4.2 images :

I transferred the host to KVM, and now
the same SSVM/CPVM
images are
running fine for the last 30min ( so I
assume it works
fine...).
Something seems to be wrong with the LXC
side :S
Anyone wants to invest some time to
troubleshoot? I'll
open a ticket also.
