Hi,

I’m adding a new compute host

```auto
onehost create hostname -i kvm -v kvm

```

but I’m getting this error in monitor.log

Error parsing start message for host 21: ARCH=x86\_64 MODELNAME=“Intel(R) Xeon(R) CPU X5650 @ 2.67GHz” HYPERVISOR=kvm  
[…]

Any idea what could be the problem?

Thanks  
Jaime

Hi,

firewall, firewall, firewall!!!  
Port 4124 was blocked so all the monitoring traffic from compute host to frontend on port 4124 was being dropped.  
Once opened the port, the node has been configured normally.

Thanks  
Jaime
