Re: [ovirt-users] ovirt 3.6 python sdk how to find logical network from a host nic?

[Huan He (huhe)]

Hi Juan,

Thanks! It works. 

One more question, do you know how to do ³save network configuration² in
the api? I did the following

Params.Action(force=1, check_connectivity=1, host_nics=host_nics)

but the gui says the network configuration is not saved. I can¹t find any
relevant params in the Action.

Thanks,
Huan

[ovirt-users] ovirt 3.6 python sdk how to find logical network from a host nic?

[Huan He (huhe)]

Assuming the logical network ovirtmgmt has been configured in host NIC enp6s0.

host = api.hosts.get('host-123')
host_nic = host.nics.get('enp6s0')

How to get the logical network name ovirtmgmt?

I basically need to find ovirtmgmt is configured in which NIC.

Thanks,
Huan

Re: [ovirt-users] Cannot locate vdsm package, possible cause is incorrect channels

[Huan He (huhe)]

I wonder if it has something to do with the centos version? I have


[root@host-182 ~]# uname -a

Linux host-182 2.6.32-642.3.1.el6.x86_64 #1 SMP Tue Jul 12 18:30:56 UTC 2016

Subject: Cannot locate vdsm package, possible cause is incorrect channels

I have ovirt engine 3.6 on centos 6.5 and tried to add centos 6.5 host.

I used the command below to install the host

yum localinstall 
http://plain.resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm


The ovirt repo are listed below.


I tried to uncomment out the baseurl, still got the same issue. Any idea?

It looks to me it failed to find the vdsm pkgs.

Thanks,
Huan

Hi Ondra,

Thinking about to upgrade to v4, but I can’t find host nic and bonding
example in the link you provided
https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples

Thanks,

Re: [ovirt-users] storage domain operation python api sample codes needed

[Huan He (huhe)]

Thanks Ondra. 

I am able to do the storage, but stuck in the host nic. I have rhvm 4.0
beta, and the sdk seems still v3.6.

Who knows where I can find the sample and doc for v3?

Thanks,
Huan

[ovirt-users] storage domain operation python api sample codes needed

[Huan He (huhe)]

Hi,

I can't figure out how to do the following, a sample code will be helpful.

Put a storage domain in maintenance mode
Detach the storage domain
Remove the storage domain

By the way, do you have an API doc or wiki?

Thanks,
Huab
