[ovirt-devel] ovirt-host-deploy and python3

[Tomáš Golembiovský]

Hi,

I'm trying to reinstall a CentOS host (using master-snapshot) and I
noticed otopi is trying to use python3 while the ovirt-host-deploy is
not yet fully python3 compatible:


> 2018-05-03 21:35:56,855+0200 DEBUG otopi.plugins.otopi.system.info info._init:39 SYSTEM INFORMATION - BEGIN

and then later:

There is definitely a bug (or at least weirdness) in host-deploy -- why
use .decode() on object returned by codecs.open()?

But also, should host-deploy be already python3 compatible and is this
otopi behaviour expected?
