hi David,

Could you share your engine log and version?
Also, the users mailing list may be better for this thread.

[Engine-devel] ovirt engine sdk

[navin p]

Hi,
I've written the following python program after configuring ovirt.


from ovirtsdk.xml import params
from ovirtsdk.api import API



api=API(url='http://XYZ:80',username='ABC',password='123')

print "\n**VMS\n"

vmlist = api.vms.list()
hostlist = api.hosts.list()
evenlist = api.events.list();


for vm in vmlist:
print vm.name,vm.memory,vm.id,vm.os.kernel,vm.cluster.id,vm.start_time

print "\n**HOSTS \n"

for host in hostlist:
print host.name

#print "\n**EVENTS \n"

#for evt in evenlist:
 #   print evt.description

It prints the output as

*VMS

fedora18 2147483648 3e4634b7-82a9-4c4f-8599-0f9092a9258e None

99408929-82cf-4dc7-a532-9d998063fa95 None

**HOSTS 

omwin.ind.hp.com

Now i want to get the statistics for each vm like the memory used and
memory installed etc in python. How do i go about getting them ? Do we have
something like a header file in C or C++ where i can see the member
variables and then get the statistics ?

vm object has statistics sub-collection, you can access it by: 
vm.statistics.list(),

in python, you can see object's attributes by accessing 
__dict__/__getattr__/dir(object)/etc.,
vm.__dict__ will do the job for you, however i'd suggest you using some IDE 
(i'm using Eclipse + PyDev plugin),
this way you'll be able accessing object attributes simply by Ctrl+SPACE 
auto-completion.

me atleast for list attributes.

for vm in vmlist:
print vm.name,vm.memory,vm.id,vm.os.kernel,vm.cluster.id,vm.start_time
#print help(vm.statistics.list())
vmslist = vm.statistics.list()
for i in vmslist:
   print i.get_name()

prints

memory.installed
memory.used
cpu.current.guest
cpu.current.hypervisor
cpu.current.total

but i need the values of memory.installed and memory.used .

Also where do i get the Java SDK and jars ? I looked at maven but it was
1.0 version of SDK.

statistic holders are complex types, you can fetch data by:

i.unit // the unit of the holder data
i.values.value[0].datum // actual data

central repo has 1.0.0.2-1, see [1], deployment details can be found at [2], 
wiki at [3].

[Engine-devel] default Vm memory size

[Laszlo Hornyak]

Hi,

The default Vm size is 512 MB now. I think A bit more could be useful, e.g. a 
fedora installer won't start with 512 MB.
What about 1024 MB?

thx,
Laszlo

Upcoming "Instance Types" would be the means to handle that rather than 
the "Blank" template.
Also there's work around integrating libosinfo for validating for 
minimum RAM per guest OS.

but until then, why not change the default to 1GB which i hope is a one 
liner?
