Hi all,
I tried adding a second NIC to a KVM guest, but it never shows up in the
guest. I noticed that the necessary parameters weren't in the
/zones/UUID/root/startvm script so I added them and rebooted the zone, at
which point I found that the startvm script is rewritten every time the
zone is booted. Obviously whatever makes that script doesn't understand
multiple NICs.
Is this a known bug? Is it fixed? I'm running a custom build
of joyent_20151204T225629Z and I'm sure I could build a newer one if I had
to. (I did "lose" the guest I was using to do the builds by accident).
Cheers,
Lloyd
