Dear all,
I'm a happy lxc (lxd) user with a need to add a bunch of KVM images to the
mix. More importantly I need to have some simple frontend to give users the
ability to quickly run some VMs for testing.
Researching the topic brought me to virt-manager and from there libvirt.
I've had however a hard time to answer a few questions that I hope this
list can help me with:
1) is the libvirt-lxc driver actively developed? there's been a lot of
upgrades to lxc and there seems to be relatively little activity on the lxc
driver
2) is libvirt-lxc to be used in production to begin with? every single
guide I found about libvirt pretty much points to KVM usage, with simple
/bin/sh examples with lxc. Furthermore stuff like virt-install seems to be
exclusively catered to full os/KVM images creation, with no obvious way to
create a container image.
thanks for any input, even just docs I missed that explain the avove would
be most helpful.

Yes it is. I don't know what are the features that lxc-tools introduced
and looking into their news files it seems like they are mostly fixing
bugs rather than introducing new functionality. Moreover, lxc-tools come
with some infrastructure (e.g. prepared images for containers). Libvirt
doesn't have those.

That's because KVM (well, qemu) is our most intense developed driver.
But LXC gets some attention too. I think it is production ready and if
you give it some testing you'll find the same.

thank you Michal, appreciate your input, I'll invest some more time and set
up a full test system mirroring our prod and see how it works out. I'm
gonna start another thread on images/templates because that's another area
where I've found a lack of information and could do with some input. thanks.
