Hello Team,
We had a power outage last week and we started observing the error on our oVirt cluster,
where all the hosts went out-of-sync.
When I select my ovirtmgmt interface it shows the out-of-sync symbol and shows IPv4
gateway ( Host - Null, DC - 10.xx..xx.xx)
Same with my VM traffic network, it shows the out-of-sync symbol and shows IPv4 gateway (
Host - Null, DC - 10.xx..xx.xx)
Please help me with my troubleshooting as we lost access to VM's access after our
power outage.
Thanks,
Dawood.

Hello
If you have done an update lately check this patch/commit
Fix default route with libnl3.8+
Since libnl3.8, the nl_addr_parse function does not return 'none' anymore for
'default', but it returns a 0.0.0.0/0 addr.
thom311/libnl@0c0aee8
But since we depend on that value in vdsm, it never reports a default
gateway anymore, causing networks to be out of sync.
So next to 'none' we also check for '0.0.0.0/0' or '::/0'.

Thank you! Noticed I am running below libnl versions on all my hosts
yum list installed | grep libnl
libnl3.x86_64 3.9.0-1.el9
@anaconda
libnl3-cli.x86_64 3.9.0-1.el9
@anaconda
I modified the file directly
(./usr/lib/python3.9/site-packages/vdsm/network/netinfo/routes.py) based on github links
- and route['destination'] == 'none'
+ and route['destination'] in ('none', '0.0.0.0/0',
'::/0')
- if r['destination'] == 'none'
+ if r['destination'] in ('none', '0.0.0.0/0',
'::/0')
After changing this, out-of-sync errors disappeared
