Re: [Engine-devel] [Users] Related to python script for Attach Cd (.iso) to a vm
by Michael Pasternak
Hi Romil,
In general you can use api guide [1] for this, anyway here is example:
1. create vm
============
...
2. insert cdrom
===============
vm = api.vms.get(name="myvm")
cdrom = vm.cdroms.get(id="00000000-0000-0000-0000-000000000000")
isofile = params.File(id="myiso.iso")
cdrom.set_file(isofile)
cdrom.update()
3. change boot order (to boot from cdrom and then from hd)
==========================================================
os=params.OperatingSystem(boot=[params.Boot(dev='cdrom'), params.Boot(dev='hd')], ...)
api.vms.add(params.VM(name='myvm2',
os=os,
cluster=api.clusters.get('mycluster'),
template=api.templates.get('mytemplate')))
4. run vm
=========

Re: [Engine-devel] ovirt-sdk at pypi
by Michael Pasternak
Hi Toni,
do:
1. nics = api.hosts.get(name=xxx).nics
2. nics_arr = nics.list()
(change nics_arr as you need, according to __doc__, also see [1])
3. my_nics = params.HostNics(host_nic=[nics_arr[0],nics_arr[1],...])
or
my_nics = params.HostNics(host_nic=nics_arr)
4. nics.setupnetworks(action=params.Action(host_nics=my_nics))

[Engine-devel] Time to bump version to 3.2.0?
by Juan Hernandez
I think that it is time to bump the version number in the POMs and in
the RPM spec to 3.2.0:
http://gerrit.ovirt.org/8993
In general I think that we should do this immediately after each
release, bumping to the next expected version number.
Thoughts?

[Engine-devel] operation mode
by Laszlo Hornyak
Hi,
I have just run into this. Vm's have an OperationMode attribute, it can be FullVirtualized or ParaVirtualized. It appears the attribute does not play in any decision, not sent to vdsm. Can it be removed or anyone need it?
thx,
Laszlo
