[OmniOS-discuss] Ang: How to do networking between host and KVM guest?

[Dominik Hassler]

there is no need for an etherstub for your setup.

I am running the same setup as you mentioned for several kvms (GZ and NGZ) in your first e-mail and no issues from guest to {host, outside} or from host {guest, outside}.

you shold not assign an address to the vnic that will be used by the kvm.
 
can you ping your guest from the host (hostname and/or IP)? might be a hostname resulution problem.

Johan,
 
Thank you, i thought of that, but it's mentioned in oracle docs that Etherstubs are a pure software implementation of nics, so the can't communicate with the outside word, only and i need that both host and guest can do that, or did i misunderstand something?

# dladm create-etherstub etherstub
Perform this step only if you are creating a private virtual network which you want to restrict from being accessed by external systems. For a description of a private virtual network, see Overview of Network Virtualization[https://docs.oracle.com/cd/E26502_01/html/E28992/gfkbw.html#scrolltoc].

Hi all,
 
I ran into a problem, how to do networking between host and KVM guest?
 
I read a lot of oracle documentation, but the virtual networking seems to be enough differently implemented, so that i can't wrap my head around it and apply it to omniOS.
 
This is what i have, and the guest can communicate with the outside world and the host. The host communicate with the outside world, but not the guest. And if i assaign an address to vnic0, then the guest can not communicate with the host.
 
dladm show-link
LINK        CLASS     MTU    STATE    BRIDGE     OVER
e1000g0     phys      1500   up       --         --
vnic0       vnic      1500   up       --         e1000g0
 
ipadm show-addr
ADDROBJ           TYPE     STATE        ADDR
lo0/v4            static   ok           127.0.0.1/8
e1000g0/lan       static   ok           192.168.200.190/24
lo0/v6            static   ok           ::1/128
 
 
 
Any hints? please?
 
Cordial regards
 
Gordon
 
 
 
You need an internal virtual network, which you get with an internal virtual switch: Etherstub. To the etherstub you can connect any virtual interface from your host or your guest.
