Windows crash with Cumulus VX on eve-ng

[Aninda]

So, interestingly enough my system crashes as soon as I power on a Cumulus VX box in eve-ng. IOSv images work perfectly fine.

Some setup details:

- this is eve-ng on VMWare Workstation Player. I've downloaded Cumulus VX 3.7.3 (haven't tried any of the older versions).
- uname output from shell:

root@eve-ng:~# uname -a
Linux eve-ng 4.9.40-eve-ng-ukms-2+ #4 SMP Fri Sep 15 02:07:02 CEST 2017 x86_64 x86_64 x86_64 GNU/Linux

I have 8G of RAM on this thing. And like I said earlier, IOSv router images work perfectly fine. Once the system crashes, it looks like the sql db gets corrupted again and I can no longer login. I need to run a 'unl_wrapper - a restoredb' to be able to login back.

Any help would be much appreciated! Let me know if there is any other info that may be needed for this.

Cheers.

Thanks for the reply, Uldis.

I am using Cumulus VX 3.7.3. I downloaded the KVM file from their site directly, with file name 'cumulus-linux-3.7.3-vx-amd64-qemu.qcow2'. For this, I created a folder called 'cumulus-linux-3.7.3-vx-amd64-qemu' in /opt/unetlab/addons/qemu/ and then copied the file there.

Finally, converted it to hda.qcow2. Not sure what I did wrong since these appear to be the instructions listed here - https://www.eve-ng.net/documentation/ho ... -from-virl

Cheers.

Works like charm dear:
I specially created even very easy How To:
https://www.eve-ng.net/documentation/ho ... cumulus-vx
Just downloaded cumulus-linux-3.7.3-vx-amd64-qemu.qcow2

1. Create image dir
mkdir /opt/unetlab/addons/qemu/cumulus-vx-3.7.3

2. Using WinSCP or FileZilla copy orignal image in to it
3. Rename it to virtioa.qcow2
cd /opt/unetlab/addons/qemu/cumulus-vx-3.7.3
mv cumulus-linux-3.7.3-vx-amd64-qemu.qcow2 virtioa.qcow2
4. fix permissions
/opt/unetlab/wrappers/unl_wrapper -a fixpermissions

Done
Add node on topology, but make sure you have set 1024M RAM for it.
Console can be user VNC or Telnet either

Enjoy All works.

Any recommendations for QEMU Version, Arch or NIC?

I feel like my Cumulus VX switches require too much resources, and I am unable to add more than 24 interfaces on them.
