[libvirt-users] starting lxcs from within a vm using libvirt

[Robb Walker]

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 at 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 at vullbvrt69:~# virsh -c lxc:/// list --all
 Id    Name                           State
----------------------------------------------------
 -     vulslxc01                 shut off

root at vullbvrt69:~# virsh -c lxc:/// start vulslxc01
Domain vulslxc01 started


root at vullbvrt69:~# virsh -c lxc:/// console vulslxc01 --devname serial1
error: The domain is not running

root at 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
