Kernel Panic when running 2 Vendors at the same time

[eboman]

Hardware : Azure VM (Standard E20s_v3 (20 vcpus, 160 GiB memory) - i know this is not supported because of the kernel
EVE-NG Running on - Linux (ubuntu 16.04)

I have an issue where i have an Cisco IOL L3 running with an VSR1000 at the same time (even in a lab with one of each), i will get an kernel panic.

Both can run separate in a bigger lab without issues , but starting 1 router of the other vendor the panic will start.

Images i use :
hpvsr-710-CMV710-R0327L01
l3-adventerprisek9-15.4.2T.bin

Eve-ng community version : 2.0.3.-105
Qemu version 2.4.0

Maybe someone can try to replicate ? In the meanwhile i will try other versions of the images.

I got some info from the console :

[Uldis (UD)]

Azure is not in the EVE supported clouds
It is exactly because this non supported qemu and virtualization..
stop it
we do not support azure
https://www.eve-ng.net/index.php/docume ... quirement/

[eboman]

for what it is worth, seems when running vIOs images it does not occur, seems to be an combination between IOL and Qemu.

[Uldis (UD)]

it is just very bad kernel used in Azure
We do not support it.
on your own risk mate
