Hi Doug,
Thanks, you're welcome!
It's generally possible to add persistent rules by either using the legacy
/etc/rc.d/rc.local boot script (chmod +x /etc/rc.d/rc.local and put the
relevant commands at the end of the file, that way you can actually run any
commands) or by using the /etc/sysconfig/network-scripts/rule-<interface
name> e.g. rule-ovirtmgmt or rule-eno3 (just put in the file "to
172.22.20.31 priority 32764" - without quotes), however of course this
needs to be tested to verify that it works.
I forwarded the issue to the network team and hopefully they will update
soon.
Thanks in advance,

You have no idea how helpful you have been!!!!!! I’ve been having this
issue for over 2 months and starting to cause major problems.
Please let me know if you find a better solution. I’m going to wait to
hear back from you before implementing.
If we go with this workaround, is there a way to add the ip rule so it’s
persistent? I know how to make the ip route add persistent.

Hi Doug,
Yes, it looks like it did.
I'll try to catch somebody from my local oVirt/RHV networking team to take
a look at this issue, maybe there is a better solution for that issue than
my workaround.
But meanwhile you can use this workaround (ip route add + ip rule add),
just please be aware that these should be run after each host reboot, since
these commands are not persistent.
Thanks in advance,

Hi Doug,
OK, I think that I have a guess of what may have happened here...
Can you please run the following command on the (non-working) host:
ip rule add to 172.22.20.31 priority 32764
This needs to be run in addition to the ip route add ... command.
And then please run the traceroute command and let me know if that fixed
the issue.

Hi Doug,
That shouldn't really matter, since ovirtmgmt is just a bridged interface,
and unless I'm missing something it shouldn't really affect routing.
Can you please also provide the output of "ip rule" from both working and
non-working hosts ?
Thanks in advance,

We have had our network team look and they don’t know. As I said, the was
setup by Commvault. It’s almost like the ovirtmgmt interface will not
allow a route add due to the way it’s configured? They, Commvault, are
trying different things within their software to get this working, but it’s
causing us more problems. I figured I would take a shot and see if
someone, who works with the oVirt software, would have any ideas.

Hi Doug,
This is indeed quite weird...
It looks like the OS for some reason disregards the static route that you
have added.
BTW, have you verified that it's indeed was added by running "ip route"
following the "ip route add ..." command ?
Maybe somebody from the network team has an idea of what may be the cause
of this issue...

Hi Doug,
In most cases it should not be required, especially as my guess (again it
would be easier if you could post the output of the "ip a" and "ip
route")
is that the eno1 is part of the ovirtmgmt bridge.
What is the output of the "traceroute 172.22.20.31" that you get on the
host after you have added the static route?
Thanks in advance,

If I attempt to manually add the route using route add:
route add -net 172.22.20.31 netmask 255.255.255.255 gw 172.21.12.61 dev
ovirtmgmt
This static route is refused and all traffic is routed over the default

But if I use a server that doesn’t use the ovirtmgmt interface and set the
same static route, the required data is routed correctly over that static

Good Morning,
New to oVirt. We are using this with a backup solution from Commvault.
The issue that we are having is that we need to setup a static route for
specific data between 2 remote sites. The ovirtmgmt is configured with the
correct IP and gateway for the server. We need to route data over a
different gateway so that we don't "max out" the default network
connection
between the 2 sites. Example below
Ovirtmgmt IP - 172.21.5.31
Gateway IP - 172.21.0.250
We need any traffic with a destination of 172.22.20.31(Remote site) to
route over this gateway, 172.21.12.61
There are multiple servers in this configuration. Servers that are not
using the ovirtmgmt interface for their default, we are able to route the
data. The only problem is with attempting to setup a different static
route on the ovirtmgmt interfaces.
Thanks in advance for any help!!!

New subject: Creating a static route
Will do. Thanks again for all your help!! Looking forward to a confirmation of the fix
or a different solution. Either way, I know I have a working fix.

Hi Doug,
Just a small note - the commands in the rc.local should be placed *before* the very last
line (the touch ... command).
Thanks in advance,

Hi Doug,
Thanks, you're welcome!
It's generally possible to add persistent rules by either using the legacy
/etc/rc.d/rc.local boot script (chmod +x /etc/rc.d/rc.local and put the relevant commands
at the end of the file, that way you can actually run any commands) or by using the
/etc/sysconfig/network-scripts/rule-<interface name> e.g. rule-ovirtmgmt or
rule-eno3 (just put in the file "to 172.22.20.31 priority 32764" - without
quotes), however of course this needs to be tested to verify that it works.
I forwarded the issue to the network team and hopefully they will update soon.
Thanks in advance,

Lev,
You have no idea how helpful you have been!!!!!! I’ve been having this issue for over 2
months and starting to cause major problems.
Please let me know if you find a better solution. I’m going to wait to hear back from you
before implementing.
If we go with this workaround, is there a way to add the ip rule so it’s persistent? I
know how to make the ip route add persistent.

Hi Doug,
Yes, it looks like it did.
I'll try to catch somebody from my local oVirt/RHV networking team to take a look at
this issue, maybe there is a better solution for that issue than my workaround.
But meanwhile you can use this workaround (ip route add + ip rule add), just please be
aware that these should be run after each host reboot, since these commands are not
persistent.
Thanks in advance,

Hi Doug,
OK, I think that I have a guess of what may have happened here...
Can you please run the following command on the (non-working) host:
ip rule add to 172.22.20.31 priority 32764
This needs to be run in addition to the ip route add ... command.
And then please run the traceroute command and let me know if that fixed the issue.

Hi Doug,
That shouldn't really matter, since ovirtmgmt is just a bridged interface, and unless
I'm missing something it shouldn't really affect routing.
Can you please also provide the output of "ip rule" from both working and
non-working hosts ?

We have had our network team look and they don’t know. As I said, the was setup by
Commvault. It’s almost like the ovirtmgmt interface will not allow a route add due to the
way it’s configured? They, Commvault, are trying different things within their software
to get this working, but it’s causing us more problems. I figured I would take a shot and
see if someone, who works with the oVirt software, would have any ideas.

Hi Doug,
This is indeed quite weird...
It looks like the OS for some reason disregards the static route that you have added.
BTW, have you verified that it's indeed was added by running "ip route"
following the "ip route add ..." command ?
Maybe somebody from the network team has an idea of what may be the cause of this
issue...

Hi Doug,
In most cases it should not be required, especially as my guess (again it would be easier
if you could post the output of the "ip a" and "ip route") is that the
eno1 is part of the ovirtmgmt bridge.
What is the output of the "traceroute 172.22.20.31" that you get on the host
after you have added the static route?

If I attempt to manually add the route using route add:
route add -net 172.22.20.31 netmask 255.255.255.255 gw 172.21.12.61 dev ovirtmgmt
This static route is refused and all traffic is routed over the default gateway.
But if I use a server that doesn’t use the ovirtmgmt interface and set the same static
route, the required data is routed correctly over that static route.

Good Morning,
New to oVirt. We are using this with a backup solution from Commvault. The issue that we
are having is that we need to setup a static route for specific data between 2 remote
sites. The ovirtmgmt is configured with the correct IP and gateway for the server. We
need to route data over a different gateway so that we don't "max out" the
default network connection between the 2 sites. Example below
Ovirtmgmt IP - 172.21.5.31
Gateway IP - 172.21.0.250
We need any traffic with a destination of 172.22.20.31(Remote site) to route over this
gateway, 172.21.12.61
There are multiple servers in this configuration. Servers that are not using the
ovirtmgmt interface for their default, we are able to route the data. The only problem is
with attempting to setup a different static route on the ovirtmgmt interfaces.
Thanks in advance for any help!!!
