Just another ping, and please let me know if this is not the proper format to re-ask my
submitted question, but anyone else having any joy on running lxcs via libvirt launched
from within a vm?

Subject: [libvirt-users] starting lxcs from within a vm using libvirt
my goal for testing/simulations is to be able to run a vm on my desktop and within that vm
run linux containers
currently I can start an ubuntu trusty vm using libvirt as my broker to qemu or
qemu-system-x86_64 directly and start a saucy-based lxc using lxc-tools. I invoke
lxc-start -n name -f configfile and within a few seconds I'm logged into my saucy
based lxc. I can't start the lxc thru libvirt i.e. virsh -c lxc:/// start domain
Again, if I try to use libvirt to "install" and start the lxc from within the
vm, no joy. Results below:
>>
root@vullbvrt69:~# virt-install --connect lxc:/// -n vulslxc01 -r 512 --filesystem
/qemu_lxc/ss_140521/,/ --serial pty --serial pty
Starting install...
Creating domain... | 0 B
00:00
error: failed to get domain '22542'
error: Domain not found: No domain with matching name '22542'
Domain creation completed. You can restart your domain by running:
root@vullbvrt69:~# virsh -c lxc:/// list --all
Id Name State
----------------------------------------------------
- vulslxc01 shut off
root@vullbvrt69:~# virsh -c lxc:/// start vulslxc01
Domain vulslxc01 started
root@vullbvrt69:~# virsh -c lxc:/// console vulslxc01 --devname serial1
error: The domain is not running
root@vullbvrt69:~# virsh -c lxc:/// list --all
Id Name State
----------------------------------------------------
- vulslxc01 shut off

My physical desktop is running precise 12.04.4
----qemu-kvm 1.0+noroms-0ubuntu14.15
----libvirt-bin 0.9.8-2ubuntu17.19
----lxc 0.7.5-3ubuntu69
This physical machine launches the trusty vm from which in turn I'm trying to run lxcs
via libvirt
Trusty vm
----libvirt-bin 1.2.2-0ubuntu13.1.1
----lxc 1.0.4-0ubuntu0.1
The saucy lxc was not created using lxc templates just a normal minbase debootstrap.
I have run virt-install with -d. Nothing obvious jumps out except the above Domain not
found
virsh -c lxc:/// -d4 -l debug.out start domain_name dumps nothing into debug.out
thx in advance for any and all help and apolgies in advance if I've dropped critical
info to help sort this out
