Re: LXC support (limits)

[Erik Weber]

I'm not very familiar with the lxc-integration, but I would suggest
checking out the container service ShapeBlue has created.

Re: LXC container template for CloudStack

[Cloud List]

Thanks Kishan.

Have tried downloading the template and create a container on my LXC
cluster (host is running Ubuntu), and it fails. Not too sure if it's
because I tried to spin off a CentOS 7 container on an Ubuntu 12.04 LXC
host?I understand that for container, the kernel of the guest container
must be the same as the host OS?

Thank you.

Re: lxc on cloudstack

[Rajani Karuturi]

registering the template with requireshvm=false or executing the below query 
worked for me
update vm_template set hvm=0 where id=‘TEMPLATE_ID’;

I don’t know what the flag does or why it doesn’t work with lxc.

 what is the mean 'they are not HVM enabled' ?

Sure! In fact, that was in a blog post that never got released on our side
:S I also have the host build piece documented. Where it would be the best
to drop that? In the LXC section of the doc or as an annexe or in the wiki?

Re: LXC template

[chinu shah]

Thank you Francois for the information.

Please could you tell me which cloudstack template to use for spawning
systems VMS on a LXC to spawn containers. I used LXC template found in
database which was very old
 | 10 | SystemVM Template (LXC) |
http://download.cloud.com/templates/acton/acton-systemvm-02062012.qcow2.bz2|
SYSTEM | LXC | which did not work as cloudstack release was too old,
then I tried with | 3 | SystemVM Template (KVM) |
http://download.cloud.com/templates/4.2/systemvmtemplate-2013-06-12-master-kvm.qcow2.bz2|
SYSTEM | KVM. Still my system VMs were rebooting only 1 VM is up at a
time. Any Advice would be appreciated

Thank you

Regards,
Chinu

Re: LXC template

[Francois Gaudreault]

You need a real hypervisor to run your SSVM and CPVM (ie. KVM, Xen, 
etc.) You can't run the SSVM only on LXC.

回复: Re: lxc 虚拟机启动失败

[yuchengao828]

虚机开不出来，排查思路一般是这样：
首先看下资源情况，主机、主存储、二级存储是否正常，资源是否足够 再看SSVM是否正常 再看模版

RE: LXC

[Musayev, Ilya]

Openshift, to best of my knowledge, leverages advanced SELinux rules  and not 
LXC for their cartridges. They presented on CCC13 and when asked why would you 
not run LXC instead, response was we don't think its mature enough... I don't 
know what to make of their response, but I guess being redhat they would know 
better.
