Instead of having to update these flavor.rb files every time a
new version of CentOS/RHEL come out let's dynamically pick up
the version (7,8,9) from the machine.
This was inspired slightly by the Rocky Linux guest flavor.rb.
Starting a rocky 9 box (having nfs shares) fails with: `No match for argument: nfs-utils-lib`.
Apparently Rocky 9 does not have a `nfs-utils-lib` but mounting nfs shares without nfs-utils-lib works fine.
So updating the nfs client install to only install `nfs-utils-lib` if the package is available. That way older rhel clones
should continue to work as well.
CentOS 8+ and Fedora 30+ no longer have the alias "nfs" for "nfs-server"
systemd service.
This shouldn't break backward compatibility, since "nfs-server" service
is available on all supported redhat systems that have systemctl binary.
Fixes#10838
Extra options are extracted from the machine configuration for the
network being configured to allow for customized network manager
behavior. The network entries must be filtered to remove non-network
entries (like port forwards) before accessing by index.
Fixes#9546
Update capability to use guest inspection module for determining
correct actions to execute. When systemd is in use restart the
correct active service, either NetworkManager or networkd. Default
to using the original service restart when systemd service is not
found.
Reduce the total number of commands run to configure interfaces. If
a service reload/restart is required, only execute it once instead
of once per device. When nm is managing a device, the explicit up
is not required.
Properly detects NetworkManager on guest as well as devices controlled
by NetworkManager. Provides configuration option to enable/disbale
NetworkManager control on devices.
`/etc/init.d/network restart` already restart NM and shutdown interfaces.
In start() :
```
if [ "$(LANG=C nmcli -t --fields running general status 2>/dev/null)" = "running" ]; then
nmcli connection reload
fi
```
In stop() :
```
for i in $vpninterfaces $xdslinterfaces $bridgeinterfaces $vlaninterfaces $remaining; do
unset DEVICE TYPE
(. ./ifcfg-$i
if [ -z "$DEVICE" ] ; then DEVICE="$i"; fi
if ! check_device_down $DEVICE; then
action $"Shutting down interface $i: " ./ifdown $i boot
[ $? -ne 0 ] && rc=1
fi
)
done
```
Where $remaining include all "others" interfaces including eth*
This reverts commit 166d10d4e16836e908be0bd94c2f671cac2b38b4.
RHEL-7 / Current Fedora versions tend to use NetworkManager for
configuring the networks, and `service network restart` might fail.
If the `NetworkManager` service is running, we should restart it,
otherwise we try restarting `network`.
When configuring network devices force NetworkManager to reload new
configuration files as they appear. This prevents NetworkManager from
attempting to continue managing devices on initial start up.
Previously this was very complicated trying to flip between Ruby and
bash. This commit uses a single bash command that decides between yum
and dnf in the script itself.
