RFE: create new instance with option to modify used network

[jscotka]

Hi,
Now when creating new instances like: virt-deploy create f fedora-21
I'm unable to modify used network (it is created under default network)
It would be nice to have some option like --network=[default,...] to choose network definition file for usage and modifiing.
Usecase is: I would like to chnage network parameteres and affecting default network is not good option. (like add domain name, create it in various ways, and do not break created default virsh network)

Thanks&Regards

It could be able to modify all default parameters from: /usr/lib/python2.7/site-packages/virtdeploy/drivers/libvirt.py somehow. I can imagine some solution via config file in ~/.virt-deploy.conf or pass config file directly to command.
It could be in some format to allow modify parameters for various vypervisors like:

~/.virt-deploy.conf:
[libvirt]
DEFAULT_NET = 'default'
DEFAULT_POOL = 'default'
BASE_FORMAT = 'qcow2'
BASE_SIZE = '20G'
INSTANCE_DEFAULTS = {
'cpus': 2,
'memory': 1024,
'arch': 'x86_64',
'network': DEFAULT_NET,
'pool': DEFAULT_POOL,
'password': None,
}

I've checked driver file libvirt.py and there is more thig what shoud be good to modify by config:
like:
URL of machine
uri='qemu:///system'
how crate name and where to store discs:
now it is in : name = '{0}-{1}-{2}'.format(vmid, template, kwargs['arch'])
my preferred name is name=hostname=dnsname (instead of adding fedora and arch to name)
and where to store images : now there is image = '{0}.qcow2'.format(name)
