2 Nexus 9000v images at same time

Post by jonaspaulo » Wed Nov 14, 2018 1:19 pm


I have an issue when launching a second nexus 9000v image. The first one works but the second one not.
It always gets stuck in a boot loop or goes to bash-4.2# prompt.
Also the one that works after a reboot goes to bash-4.2#.

Any clues?

I am using the following versions:

Eve-NG runnning on a VM on KVM (with vmx enabled and everything): root@eve-ng:/opt/unetlab/schema# dpkg -l eve-ng
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description
ii eve-ng 2.0.3-92 amd64 A new generation software for networking labs.

Nexus nxosv9k-7.0.3.I7.4 with 8GB RAm and 2 vcpus

My server has 92 GB ram and 16vcpus - Intel XeonD-1500

Also my xml file for the eve VM is:
