Hi Dinu, you can change the system service offering in 4.2. refer to this link http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Admin_Guide/system-service-offerings.html This is for 4.1 but will work with 4.2 as well. As per the overcommit settings getting applied to the rou

Thanks Bharat, As far as I'm aware, the only way to change the default system VM offering for a domain router can be done by modifying the database (altering the disk_offerings table). One can change it when a router is not running, but with multiple routers in a cloud it may become tedious.

Hello, I'm testing ACS 4.2 with kvm. I noticed that when one configures mem.overprovisioning.factor Global/Cluster setting, chances are that the System VMs configured with an offer of 128 MB RAM will never start (namely the Domain Router and the SSVM). According to the agent.log, ACS sends li
