<div> Be sure you are not also running
KVM, VMware, or any other VM software. At this writing, only one
virtualization platform can run at a time.<br>
<br>
LXC is not a virtualization platform (because it doesn't run
multiple kernels on one CPU). So your VirtualBox freeze-ups are
probably not related to the use of LXC (but I haven't tried it
myself).<br>

Here are some of the cases that I have tried:<br>
1.) Starting a VirtualBox VM when an LXC container is already
running effectively freezes the host.<br>
2.) Starting an LXC container when a VirtualBox VM is already
booted is fine. <br>
3.) Starting another LXC container after point (2) is also
fine.<br>
4.) Starting antother VirtualBox VM after point (3) is also
fine.<br>
<br>
Could somebody kindly share some light here? It seems that the
initial startup of the VirtualBox module is the trigger here.
Does LXC and VirtualBox really could co-exists together at the
same time? <br>

Yes. They have no problem working together for me.<br>

I intend to utilize the VirtualBox VMs for
other-than-Linux-workload, whereas the LXC containers for all
Linux workload. For the info, the host is a Linux Mint 13
(3.2.0-33-generic 64-bit) using VirtualBox 4.2.4. Both
VirtualBox VM's files and LXC container's rootfs are on top of
ZFS filesystem.</div></blockquote><div><br>
I start with a newer kernel. <br>
