Let me know what is the result in your environment.

I have tried it and indeed works well for me.

In addition, as I said, it will be convenient if we have wait_for_status
function like before.

I will look into it. I would greatly appreciate if you can open a bug to
request and track it.

It's okay for me, I want to know I need to file a fedora bug? which 
component?

because I'm doing these on RHEL6.2.

will reload resource then get current resource status, however, I haven't found 
similar method in
ovirt-engine-sdk.

Are you sure you are calling api.vms.get(vm_name) each time? Or are you
doing something like this:

vm = api.vms.get(vm_name)
while vm.status.state == "suspended":
  sleep(10)

Yeah, I put 'api.vms.get(vm_name)' in a loop body like above codes.

If you are doing that the vm information is retrieved only once, not
each time. If this is the case try something like this:

while api.vms.get(VM_NAME).status.state == "suspended":
  sleep(1)

Can you share that snippet of code so that I can try to reproduce it?

Okay, I will list my snippet of code in here, you may replace 'logging'
with 'print' then remove
useless '()' if need. thanks.

Hi Juan,
Although I haven't try it, I think you're right, I should refresh VM
in loop body. 

In addition, as I said, it will be convenient if we have wait_for_status 
function like before.

 sleep(10)

Yeah, I put 'api.vms.get(vm_name)' in a loop body like above codes.

If you are doing that the vm information is retrieved only once, not
each time. If this is the case try something like this:

while api.vms.get(VM_NAME).status.state == "suspended":
 sleep(1)

Can you share that snippet of code so that I can try to reproduce it?
Okay, I will list my snippet of code in here, you may replace 'logging' 
with 'print' then remove

useless '()' if need. thanks.

Are you sure you are calling api.vms.get(vm_name) each time? Or are you
doing something like this:

vm = api.vms.get(vm_name)
while vm.status.state == "suspended":
sleep(10)

If you are doing that the vm information is retrieved only once, not
each time. If this is the case try something like this:

while api.vms.get(VM_NAME).status.state == "suspended":
sleep(1)

Can you share that snippet of code so that I can try to reproduce it?

Re: [Users] Unable to add fresh oVirt host

2012-04-27 Thread Shu Ming

How about the ouput of "brctl show" in your ovirt node?  It looks like 
that the right bridge was not created.

Are some more digging. I have discovered the following.

It seems that ovirt is not able to create the bridge. What could

somewhere?.


Ugh...I've been "over-debugging"...I was running the script wrong. 
This was getting caught in my params: 
/tmp/vds_bootstrap_f9c3a003-b221-4f7e-ae14-5b53ce31ab72.py script cmd 
= ', hense why script was getting returned in this log line: "Fri, 27 
Apr 2012 03:33:19 DEBUGgetAddress Entry. url=script"


When I run the script correctly, I get the VDS compat output per my 
original post with nothing in the bootstrap log.


is in vds_installer script. It passes "-v" to bootstrap script:

Fri, 27 Apr 2012 03:14:12 DEBUGtrying to run 
/tmp/vds_bootstrap_51b8d414-
a8fa-44f9-8613-f7819255d2eb.py script cmd =

http://mgmt.example.com:8080/Components/vds/ node.example.com 
 51b8d414-a8fa-44f9-8613-f7819255d2eb'


I was able to figure that out after changing this:

except:
print main.__doc__
return 0

to this:

except Exception, e:
print e

Why is the exception not printed? Getting this output would have saved 
my a lot of debugging time I feel :(.


It looks like my version of vdsm from rhn: vdsm-4.9-112.6.el6_2.x86_64 
is too old for my ovirt which is at version 
ovirt-engine-3.1.0_0001-1.8.el6.x86_64 built from source.


Note, that I used the following answers file to install ovirt:


[general]
OVERRIDE_IPTABLES=no
HTTP_PORT=8080
HTTPS_PORT=8443
MAC_RANGE=00:1A:4A:A8:7A:00-00:1A:4A:A8:7A:FF
