Hi Sahina,
I was able to reproduce it on my setup, it seems that when a host was
already installed and the user re-installed it, it failed to check the
host availability.
I fixed the host polling by the engine by commit
5c03a936df3a09473f1a05b973680c02280d7a5c.
You can either build from master or wait for the nightly build.
Please let me know if there are more issues.

Hi Moti,
Not sure I understand your comment about host activation flow.
commit bdd8966d97e1e02e775ee6f755d0a3637a668911 (engine: Remove mgmt
network setup from host activation) is present in our code base, but we
were not using the host activation flow.
Hi,
My fault, i had a different old thread in my mind.
The relevant part from the engine.log indicates that the host deployment
ended successfully, host was able to ping VDSM, but the first attempt to
run getVdsCaps on vdsm failed.
Could you add the relevant vdsm.log which contains the flow-ID 740c5292
which matches the same correlation-id from the engine.log ?

Here's what we tried to do.

The installation failed with "Failed to configure manamgent network on

As Kanagaraj mentioned, reverting the Change Iaf82e104: engine:
Allow engine to configure management network , fixed this issue.
From the flowchart on
http://www.ovirt.org/Features/Normalized_ovirtmgmt_Initialization, it
seems to fail on the "Configure Management Network (by setup networks)"
action.
Any help on solving this would be appreciated.

Having that said, I agree with the concept as we need to take a more holistic approach which considers other areas of the system, such as SLA policies and instance types. So in this view I'll just add that going forward the QoS element of the profile will be a reference to a policy entity which will include network QoS as well as other QoS elements. At this point we're going back to the drawing board to update the design and will publish an update asap.

Re: [Engine-devel] about govirt
I build a local sdk base on ovirt-engine-sdk-python, I do that like this:
First, I created a python file naked wrap.py, in wrap.py I have
a class naked CWrap , CWrap have some interface for get vm's information
and connect to ovirt-enginelike:
login(), getVmName(), getVmId(), getVmPort(), getVmTicket() etc.
second, I created a C file named engine-sdk.c, in this file I also implement
some interface like getVmName() etc. but in this file, all the function is
call python module like
PyObject *pyVmId;
char *vmId;
pyVmId = PyObject_CallMethod(pInstant, "getVmId", "(i)", vmIndex);
if(pyVmId == NULL)
{
DBG("ERROR:Call py Method getVmDisplayType is failed!\n");
return NULL;
}
vmId = PyString_AsString(pyVmId);
so, the local sdk is used for a client(C/S ) implemented by gtk.
Every time, when I use my client login and get vms's information, it's about
10~20 seconds.

i'm confused, are you mixing python with c? so what is CWrap/wrap.py from
python?
can you post theirs code?
