UFW Firewall enabled SystemVMs offline
We have followed the ports that Cloudstack requires and opened them in our hosts however with UFW enabled the systemvms agent disconnects. We allowed all traffic to and from the management host and opened these ufw allow proto tcp from any to any port 22 $ ufw allow proto tcp from any to any port 1798 $ ufw allow proto tcp from any to any port 16509 $ ufw allow proto tcp from any to any port 16514 $ ufw allow proto tcp from any to any port 5900:6100 $ ufw allow proto tcp from any to any port 49152:49216 What exactly is causing the systemvms to disconnect when UFW is enabled ? The moment we disable it and reboot the systemvms the agents come back online Regards, Ben McGuire Founder AeroNeave Cloud Solutions

Hi Wei, Thank you for the tip. We have made that change so we will see how things go.

Stopped VMs Not Counted CPU Cores
Is it possible to configure CS to not count running VMs in the Core count ? We have changed the global configuration but we are still limited but instances that are powered off. An an example:- We have 80 Instances deployed. The host has 96 Cores. 50% of the instances are not powered on but we are getting the insufficient capacity error. It is my understanding Cores should not count for powered off instances if I’m not mistaken. Regards, Ben McGuire Founder AeroNeave Cloud Solutions
CPU Core Widget Disappeared
Great to finally to apart of the Cloudstack community. We restarted the management server and now we have lost the CPU Core Display Widget. It may be something we changed in the Global Configuration settings but I am at a loss as to what could have caused it. Further, It would be nice to implement CPU Core percentages rather than a blanket 1 Core and more often that not that is overkill and limits the amount of virtual machines on each host. Anyway, hopefully someone could shed some light on the CPU widget issue. Regards, Ben McGuire Founder AeroNeave Cloud Solutions
