vCenter 6.7 Backup not working when IPv6 enabled

[Raudi]

Hello,

i just upgraded my test environment to vCenter 6.7 and tested the new Backup Task, but it don't work.

In /var/log/vmware/applmgmt/backup.log i found:

ERROR: BackupManager encountered an exception: While reading from '/etc/systemd/network/10-eth0.network' [line  7]: option 'gateway' in section 'Network' already exists

And the file looks like that:

root@srv10 [ /var/log/vmware/applmgmt ]# cat /etc/systemd/network/10-eth0.network

[Match]

Name=eth0

[Network]

Gateway=2a02:xxxx:xxxx:xxxx::250

Gateway=192.168.99.1

Address=2a02:xxxx:xxxx:xxxx::20/64

Address=192.168.99.20/24

IPv6AcceptRouterAdvertisements=false

DHCP=no

[DHCP]

UseDNS=false

It must be a bug in the backup function...

Kind regards

Stefan

And in the case of multiple static routes as well:

Hi,

This issue is because backup reads line by line and if it found anything duplicate it will give an error.

For get this resolved comment the line [Route] -> #[Route] and change gateway and destination to Gateway0, Destination0 and so on.

The /etc/systemd/network/10-eth0.network file should look like

#[Route]

Gateway0=x.x.x.x

Destination0=x.x.x.x

#[Route]

Gateway1=x.x.x.x

Destination1=x.x.x.x

#[Route]

Gateway2=x.x.x.x

Destination2=x.x.x.x/24

Note: If gateway does not provide proper connectivity, replace GatewayX with GATEWAY X=0.0.0.0

With Regards

Ashish

Hi Raudi, I was able to get it to work with a clever use of the [Address] and [Route] sections; here's my /etc/systemd/network/10-eth0.network. Yes, I rebooted after I made the changes, yes, I was able to ping6 2600:: and ping 8.8.8.8 after reboot. Yes I was able to successfully kick off a completed backup. Here's a good source for the layout of the file: https://wiki.archlinux.org/index.php/Systemd-networkd#network_files
