Hello everybody,
What do you think about allowing users to send cloud-init customization script directly from virt-manager ? (for
instance open-stack's GUI horizon includes this feature)
Here a blog article showing how to do with the CLI: http://blog.oddbit.com/2015/03/10/booting-cloud-images-with-libvir
t/
Would it be difficult to implement in virt-manger ?
I think pre-installed images are useful, but can't figure out how to use them efficiently with virt-manager.
Any suggestions ?
Sounds like a cool feature to me. The iso image creation sounds hacky: there surely is
a cleaner way to feed the config to cloud-init.
Something that could be interesting too is to allow creating a guest out of a virt-builder
template. Note that you can already clone an existing VM with virt-manager.
This may be a stupid idea but what about a metadata server?
Since libvirt does the network setup it should be possible for libvirt to
add in some iptables rules to redirect requests to a simple metadata server
running alongside libvirtd.
The metadata could be encoded in the vm's xml file.
We don't really want to hardcode knowledge about the cloud-init protocol
in libvirt. So any such setup needs to be done by the layer above libvirt,
using the libvirt APIs that exist as the mechanism.
I can understand that.
Are there any APIs that allow for the manipulation of the network
interfaces or provide call-outs to other tools?
If the xml VM definition is all that is needed to start a VM is there
any way to get the xml definition hold information that is used by
other tools without having to keep parallel databases of VM's.
