[ovirt-devel] OVS-based cluster adding vdsm report 'RTNETLINK answers: File exists' error in supervdsm.log in release 4.0.2

[lifuqiong]

Hi,
I want to test ovs in vdsm of release 4.0.2. And according Petr's 
helpful advice, created an ovs-based cluster and install vdsm to ovirt engine. 
But report a 'RTNETLINK answers: File exists' error as bellows.

It seems that vdsm want to  add a default gw through ' ip -4 route add default 
via 192.168.0.1' ; but of course this gateway already exists, why the vdsm will 
still add the default gateway?

[ovirt-devel] 答复: [ovirt-users] How to add ovs-based VM in version 4.0.2? Thank you

[lifuqiong]

Hi Petr:
I found that when I type virsh commands like 'virsh list' in vdsm, the 
system will force me to input username and password, Could I cancel this 
authentication step when I type 'virsh list',  If so , how can I do this?

Thank you
Mark

Hello,

don't forget you still need latest patches which are not part of
ovirt-release40 nor ovirt-release-master.

Network setup is handled by supervdsmd.service, logs are located in 
/var/log/vdsm/supervdsm.log. Network API entrypoint is in 
/usr/lib/python2.7/site-packages/vdsm/network/api.py.

Thanks! Looks like copr-be is donw now so I can't access

Please open a bz on ovirt-release component to switch to the new repo.

[ovirt-devel] problem setting up bonding via rest in ovirt 3.6.6.2

[Sven Kieske]

Hi,

I'd like to setup host network in the following way:

I have 4 interfaces: eth0, eno1, eno2, eno3

ovirtmgmt network resides on eth0 and is working.

Now I want to setup a bonding with the slave interfaces
eno2 and eno3 via the hosts "setupnetworks" function:

URL:

https://engine-fqdn/api/hosts/9cdcc85b-dd87-4dcf-9275-b993ee5b5e9c/nics/setupnetworks

Request:

{
"modified_bonds": {
"host_nic": [{
"name": "bond0",
"bonding": {
"options": {
"option": [{
"name": "mode",
"value": "1"
}, {
"name": "miimon",
"value": "100"
}]
},
"slaves": {
"host_nic": [{
"name": "eno2"
}, {
"name": "eno3"
}]
}
}
}]
}
}

Response from ovirt-engine:



Incomplete parameters
Action [hostNics] required for setupNetworks


When I look at the rsdl docs this seems perfectly fine.


I tried google with this error condition but it didn't return anything
useful unfortunately.

Your help would be greatly appreciated.

The official RH docs also do not mention anything else:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html-single/REST_API_Guide/index.html#Multiple_Network_Setup_Action

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html-single/REST_API_Guide/index.html#Bonded_Interfaces

Also this tool doesn't seem to mention anything else:

[ovirt-devel] Python code style: introducing isort

[Sandro Bonazzola]

Hi,
in project maintained by integration team we tried to adhere to some
styling rules while writing python code, one of these was related to the
import lines. After a lot of time doing this manually, we discovered isort
( https://pypi.python.org/pypi/isort/4.2.5 )

We're using it before we push our code to gerrit and a few days ago I sent
a patch for the python code within ovirt-engine:
https://gerrit.ovirt.org/61964

The configuration we're currently using is:

$ cat ~/.isort.cfg [settings] line_length=79
known_standard_library=configparser,Cheetah.Template force_single_line=True
default_section=FIRSTPARTY known_otopi=otopi
known_host_deploy=ovirt_host_deploy known_ovirt_engine=ovirt_engine
known_ovirt_engine_setup=ovirt_engine_setup
known_ovirt_setup_lib=ovirt_setup_lib known_vdsm=vdsm
known_ovirt_hosted_engine_setup=ovirt_hosted_engine_setup
sections=FUTURE,STDLIB,FIRSTPARTY,OTOPI,VDSM,HOST_DEPLOY,OVIRT_ENGINE,OVIRT_ENGINE_SETUP,OVIRT_SETUP_LIB,OVIRT_HOSTED_ENGINE_SETUP,THIRDPARTY,LOCALFOLDER
lines_between_types=2

It has been proposed to add 'isort --check-only' in check-patch.for python
projects in addition to pep8 style checking.

It has also been proposed to reach consensus on isort configuration so all
the python code
within ovirt project will have same styling.

I'd like to get some feedback about these proposal in order to decide how
to procede.

Thanks,

[ovirt-devel] Which GlusterFS for oVirt 4.1?

[Sandro Bonazzola]

Hi,
currently we're building and composing master (will become 4.1) assuming
GlusterFS 3.7 will be used.
I see that 3.8 is available in Fedora 24 and on CentOS Storage SIG.
Is it time to move to 3.8 for 4.1?
