vSLX - issue powering on virtual chassis.

vSLX - issue powering on virtual chassis.

Hi,

I installed vSLX 2.3.0 on Ubuntu 16.04 system and I’m using slxos 20.1.1 as OS. I followed the installation instructions in slx-20.1.1-vslx-guide.pdf and installed the whole thing into a KVM VM with CPU=host setting and nested virtualization turned on (AMD proc, so I have “svm” flag present in /proc/cpuinfo). 

I’m able to create a template with example in the manual and I’m able to create a chassis, but when I turn it on (or start), things go wrong quite quickly and the whole process freezes. With “start” command in vsh I dont even get to any prompt, it just says that machine was powered on successfuly.

/var/log/libvirt/qemu/PB_1_av1.log says this:

Any idea, anyone?

I have a feeling that things go wrong when creating tuntap interface, but I’m not sure. 

Thank you very much for all your help!

Hi, thank you for your patience while I looked in to this for you. I tried to run this past our Data Center techs but I’m told vSLX is only supported by our service engineers (SEs) at the moment. I’d recommend reaching out to your SE for help with this. If you’re unsure who to reach out to for your SE, you can always go here and we will find you a local contact to speak with: https://www.extremenetworks.com/contact-sales/

as additional info - when I power-on the chassis and qemu process is running, this interfaces are created:

They are in puzzling state: UNKNOWN.
