Hi all,
I am trying to bring up lxc's using Libvirt JAVA API. I do the following:
conn = Connect("lxc:\\\")
xml_config = "<domain> .... <\domain>"
dom = conn.domainCreateXML(xml_config, 0)
dom.create()
Using the above code, I am able to start a domain but the domain is not
visible within the "lxc" list, i.e
when I use the command "lxc-ls --fancy", the domain that was created cannot
be viewed, although, when I use the function conn.listDomains(), I can view
the domain.
As a work-around if I use the "lxc-create -t <OS> -n <name>"
command
followed by "conn.domainDefineXML(xml_config)", I can view the domain
within "lxc-ls --fancy"
Any one has observed this problem earlier and is there a way I can create
the domain without using "lxc-create ..." command and still list the domain
on the "lxc-ls --fancy" list?
Thank you,
Anu

That's expected and correct. Libvirt does not use lxc tools to manage
Linux containers. Libvirt manages everything by itself and talks to the
kernel directly. Thus containers created in libvirt are not visible to
lxc tools and containers created using lxc tools are not visible to
libvirt. In other words, use either lxc tools or libvirt but do not try
to mix them.
If you want to manage libvirt's containers from a command line, use
virsh. For example, "virsh list --all" will show you all containers
libvirt knows about.

Thanks for the explanation Jiri!
