**I'm hooked...**
|
|
|
|
I attended SCaLE 11x, my first technical conference, and had an amazing
|
|
time. My favorite talk was Michael Day's "`Advancements with Open
|
|
Virtualization &
|
|
KVM <https://code.ncultra.org/2013/02/scale-11x-open-virtualization/>`__\ "
|
|
(link to slides). Michael's presentation inspired me to continue my work
|
|
on virt-back.
|
|
|
|
During my trip home I used the in-flight wifi to push this
|
|
`commit <https://bitbucket.org/russellballestrini/virt-back/commits/d6dff27323650bf784cc284f676299ffe07953cb>`__
|
|
into the cloud from the clouds! This particular commit re-factored the
|
|
dom object list generation into a simple-to-use class called Domfetcher.
|
|
Domfetcher abstracts the libvirt API and grants access to the following
|
|
helper methods:
|
|
|
|
| **get\_all\_doms( )**
|
|
| Return a list of all dom objects
|
|
|
|
| **get\_doms\_by\_names( guest\_names=[] )**
|
|
| Accept a list of guest\_names, return a list of related dom objects
|
|
|
|
| **get\_running\_doms( )**
|
|
| Return a list of running dom objects
|
|
|
|
| **get\_shutoff\_doms( )**
|
|
| Return a list of shutoff but defined dom objects
|
|
|
|
**This is an example of how to use Domfetcher:**
|
|
|
|
::
|
|
|
|
import virtback
|
|
|
|
# optionally supply hypervisor uri
|
|
domfetcher = virtback.Domfetcher()
|
|
|
|
doms = domfetcher.get_running_doms()
|
|
|
|
for dom in doms:
|
|
print dom.name()
|
|
|
|
for dom in doms:
|
|
print dom.info()
|
|
|
|
for dom in doms:
|
|
print dom.shutdown()
