network not working on newly created hp-ux guest

[Skeens]

I've only been working with HPVM for a short time, so please bear with me-- I am running 11iv3 on an rx2800 i2 with IVM 4.2.5 and have created an 11iv3 guest. I cannot reach the guest on the network. I created a virtual switch associated with the only lan port with an available connection on the box.

And I added that switch to my vm.

But I cannot get in or out of my vm...ping, ftp, telnet, ssh, etc. all time out.

What did I miss during the configuration of this guest?

Thanks in advance.

[melvyn burnard]

what is your network configuration on the Guest OS?
netstat -in
nwmgr
ifconfig lan0
ifconfig lan1

[Skeens]

Thanks for your response, Melvyn. Here is the information you requested from the guest:

# netstat -in

# ifconfig lan1

I originally configured the guest with lan0, but that was not working, so tried lan1 since it seemed the macid corresponded to lan1 (output from hpvmnetfor vmswitch0's mac address corresponds to lan1 on guest itself). Still doesn't work with lan1 though.

Thanks for your help.

Bonsoir,

Are you sure that you have posted information from the GUEST as asked by melvyn ?

It seems that yes (did the check with mac adresses). So, you have the same IP in the Guest and in the VM host : 10.200.10.39.

It simply can't work. As with any physical box, IP addresses must be unique for each NIC or vNIC.

Yes, I do not wish for the IP address to be the same on the host as the guest. The host is intended to have the .38 address and it does report this when I issue ifconfig lan0. The guest should have the .39 address, and it does report this when I issue ifconfig lan1 on the guest. netstat -in on the host says:

# netstat -in
Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll
lo0 32808 127.0.0.0 127.0.0.1 338 0 338 0 0
lan0:1* 1500 10.200.10.0 10.200.10.39 102 0 102 0 0
lan0 1500 10.200.10.0 10.200.10.38 498 0 342 0 0

Thank you for your response!

lan0:1* 1500 10.200.10.0 10.200.10.39 102 0 102 0 0

--> Do you have MC/ServiceGuard running on the host ? Check with command 'cmviewcl'

If yes it probably means that a package has the same IP than the Guest..

If this package is there to start the VM in a 'VM as package' configuration, you don't need to specify the VM's IP in the package configuration. In this case stop the package, modify configuration to delete the IP, then restart the VM by starting the package.

If this package has nothing to do with the VM, but has its own utility, it simply means that you have an IP conflict : one of the 2 IP must be modified.

--> Now, if MC/ServiceGuard is not running at all, where is this IP coming from ? And what for ?

If you can safely state that it is useless at host level, you can delete it with :

ifconfig lan0:1 0

And probably edit /etc/rc.config.d/netconf

I am to leave for the moment.

Eric, thank you! I do not have ServiceGuard installed, but I DID have Secure Resource Partitions configured at one time and I was using the same name/IP address for that compartment. I removed reference to the compartment in the netconf file and rebooted the host and now my network on my guest is working!

Again, many thanks. I was banging my head on my keyboard about this for 2 days. :(
