IP conflict between Host and Guest

[mohdamir]

Hi gurus,
We have setup 6 VM on RX8640 and each VM using 4 ports on network switch that combined using Auto Port Aggregation (APA).On our host, we just using one port only. The problem is when we try to telnet to VM1, it direct to host instead of VM1.Then on VM1 I try to redo the IP configuration. It works fine but one minute later, it will direct to the host again. Need your help.

This sounds to me like a name resolution problem or a non-unique IP address. Please check this.

Hello,

do you mean that you have configured APA in the guests ? This is not supported.

If this is not the case, check all your systems (VM host and the guests) for IP ambiguity.

I've configured the APA on the host, not on the guest. Well as far as I noticed every VM have an unique IP.

Check each IP and hostname with nslookup and consider to post "hpvmnet".

[mohdamir]

As requested.
When I try run nslookup, found nothing unusual.

You are using 6 (!) different APA devices - do you really have sooo many NICs or just 4?

Check your APA config.

[mohdamir]

Yup.. 4 NIC or network switch ports combined to be one APA as named as vsw900, vsw901..etc. I will check on it

Link aggregation configuration at network switch is not correct. Thanks for your reply :)
