Hi,

I have trouble when I want to load a lab with CSR1Kv's in it.

Fx. the current one consists of 3 CSR's (Running Everest). When I start the lab, 2 of them loads just fine, but the 3rd one just hangs and never starts the booting process.

I tried turning off CPU limiting and everything else I could think of as well as stopping the individual problem node and starting it again, but to no avail.

Any tips/suggestions for troubleshooting this phenomenon?

Thanks in advance!

each CSR need at least 1 core from your CPU and ate least 3G ram..
So your eve VM must have x8 virt CPU and 16G ram to get this lab UP !!!!!!

Thanks for your reply.

My EVE VM has 100Gb of memory allocated to it, and its running on 8 cores in total, so it should be plenty to get these 3 up and running.
After I used the "wipe" function on the problem node, it started up just fine. So obviously something is up with it.

Can I provide any further information to troubleshoot this behaviour?

post me all outputs of these CLI commands here:

uname -a

dpkg -l eve-ng

brctl show

df -h

kvm-ok

and please show me how much you have RAM assigned for eve and HDD space

Thanks again for your time!

These are the outputs:

then it is only your CPU weakness !!!
Above information is ok.
Your CPU simply cannot carry Everest more than 2 nodes..
How many Cores are assigned for EVE VM??
check your CPU
and what is your CPU model?
Like Intel Xeon 5680 or something...
UD

I have 2 CPU's in the box.
They are Intel X5570's.

I have 8 vCPU's assigned to the VM (its the only VM on the ESXi hypervisor).

Right now I have the lab started (after the wipe I mentioned) and its running the 3 Everest images just fine, with 38% CPU usage (using the Status page in EVE-NG) and without CPU limiting, so it certainly has the horsepower to run them stable enough. Its just the boot up process that doesn't work every now and again.

Thanks!

everest is very heavy, try CSR 3.17 its the best for CPU as well
