limitation on number of ethernet interfaces (24 ports)???

Before posting something, READ the changelog, WATCH the videos, howto and provide following:
Your install is: Bare metal, ESXi, what CPU model, RAM, HD, what EVE version you have, output of the uname -a and any other info that might help us faster.

limitation on number of ethernet interfaces (24 ports)???

Post by simonatack » Thu Nov 19, 2020 2:10 am

I have downloaded the community edition and tried to setup a proposed network to try things out. all worked well until I added a couple of new switches that emulated real kit that exists (so to this end I wanted to reuse my automation deployment so made sure the devices had correct number of ethernet ports eg 32 or 56. I then cannot start the devices with such large number of ports (they are cumulus vx). I tried such number of ports as vyos and linux and had the same issue. you click start and it tries and then just seems to stop.

I can make it work with 24 ports but going to 26 seems to fail.

finding issue is difficult.

I did manage to get to a console at the right time and see the following

no slot/function available for virtio-net-pci

from the looks of things it seems there might a limit on the number of pci devices, as i found a mention on the web for issues with qemu/kvm with >30 pci devices and looking at this with a 24 ports in eve-ng reprts 30 pci devices inside

Is this a community edition issue?

Is there a work around/fix?
