Solaris 11 LDOM guest network not working

UNIX for Beginners Q & A
1

I'm really stuck here. I've created an LDOM on a SPARC T4-1 with Solaris 11.4 to run a copy of Linux for SPARC. I got the Linux ISO installed and Linux itself installed and booted OK. The only thing is is that there's no networking available in the Linux guest.

This question is basically the same as this one: https://www.unix.com/solaris/275859-ldom-solaris-11-add-network-vsw-virtual-switch.html but I wasn't able to figure it out even after reading that. Can someone please help me with this particular case?

Here's the same info Wittman gave in his OP:

Does any of this give a clue as to what might be wrong?

Strange combination, sparc linux on Solaris ldom, to notice at first.
I do not think that is supported or condoned by Oracle, but since you installed / booted it lets take a look.

Can you show output of :

ldm list -l linux

What linux distribution is this ?

"Strange combination, sparc linux on Solaris ldom, to notice at first."
No doubt but I have a program that only runs in Linux. If I can get it to work here I won't need a separate machine just for that.

"I do not think that is supported or condoned by Oracle"
Definitely not. They say as much. Not that it matters since I'm just one person and don't have an Oracle support account.

OK, am I ever embarrassed. The solution turned out to be as simple as just turning on the networking inside the guest. Doh!

Thanks for taking the time to look at this.

Looks fine.
As far as i could read online, it's some kind of Oracle Linux derivative which in turn is RHEL base.

Can we see inside the guest ..

ls -lrt /etc/sysconfig/network-scripts/ifcfg-e*

P.S I just saw you figured it out, so you can disregard this.
You still might want to check out those network files to configure onboot network and / or static IP

Oh OK - thanks. That's good to know.

It says:

[root@localhost ~]# ls -lrt /etc/sysconfig/network-scripts/ifcfg-e*
-rw-r--r--. 1 root root 136 Nov  1 18:03 /etc/sysconfig/network-scripts/ifcfg-eth1
-rw-r--r--. 1 root root 136 Nov  1 18:03 /etc/sysconfig/network-scripts/ifcfg-eth0
[root@localhost ~]#

I get

[root@localhost ~]# more /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=00:14:4F:F8:1F:C0
TYPE=Ethernet
UUID=8f2adc41-c96e-4687-8dc5-9b15effe7406
ONBOOT=no
NM_CONTROLLED=yes
BOOTPROTO=dhcp
[root@localhost ~]#

Great point. I will change ONBOOT=no to yes. I don't need a static IP for this system (though the T4 host does have one).

Anyway, I just finished doing a yum update which updated/installed 503 packages, so I'd say it's pretty much working.

Great you have everything working.
Depending on the network topology and desired level of redundancy of network, one might configure it a bit more.

If you have one cable in physical machine connected to one switch then you can remove additional interface from linux LDOM.
Since they are connected to same VSW, there is little point in having an extra interface.

In case you have multiple network ports connected take a look at aggregating interfaces together followed by creation of VSW over that interface.
This is only one of many ways, selection depends on network topology etc.

If you have any questions or doubts feel free to post here.
We shall try to advise the best approach on redundancy of network or any other component in Solaris systems.

That's a good point. There's just one Ethernet cable connected to the T4 so I don't need the ETH1 interface in the guest at all.

Thanks again for your help My next project is to port a Solaris 10 installation from an M3000 onto the T4. My plan at the moment is to make a flar archive of the M3000 and then load that into a new zone on the T4. Does that sound reasonable?
