Hi,

I was able to successfully create a QEMU EXOS VM and console into it. Strangely though, when I create the QEMU VM, i choose 24 ports in e1000 type adapter however when i issue the 'show ports' command in EXOS, it only shows 12 ports. Is this limitation built into EXOS or QEMU? 

Anyone has any experience in this setup? Is there a way to overcome this limitation?

Thanks

If I remember correctly, this is an EXOS VM limitation.  I'm not aware of a way around this.

Drew thanks for the response. If its a EXOS limitation, then its a pity. So i'm guessing there's no way to simulate 24,48 port switches?

Understood. I think you and Daniel Flouret both work for Extreme. If so, please feed this as a feature request into the next release of the VM, if its a maintained product. I think it'll be incredibly useful to have support for 48 ports on the EXOS VM to simulate some larger topologies in tools like GNS3.

Hi,

this is not a product per se, more a free tool to play with, but we can have a look why there's such limitation. Not sure if we can remove it easily, so we can't promise anything.

Hi Grosjean, Yes its understood its not a sold product. I think it will benefit the community though by allowing the capability to simulate and troubleshoot large (actual) deployed networks.

Looking forward to the info you find out.

After asking around, it looks like this limit may more be of an Hypervisor limit than vEXOS. Looks like some were able to have 32 ports on VM (qemu). It may vary with the version.

Grosjean, Stephane,

Here's the config for my qemu. Please check if possible to see if I've mis configured something.

even on my qemu VM, i'm able to configure 32 ports, but when i start up the EXOS VM, it only recognizes 12. I'm determining that its recognizing only 12 because show port command only shows 12.

Check our GitHub page - https://github.com/extremenetworks/Virtual_EXOS
EXOS 16.1.2.14 is posted there.  v16.1.3 should be arriving soon and I'll post it there too.

Late to the party here, but I can confirm that 12 ports seems to be the limit in EXOS in Qemu (2.5.0).  I also tested out Arista's vEOS in Qemu, and while 24 ports makes it go berserk, it can handle 17 ports (1 management, 16 switchports ) flawlessly.
