Increase max number of VMs in a host?
Hi,
I am not able to add a new VM instance through CloudStack because the
number of VMs in my KVM hypervisor hosts have reached 50.
Is there a way to increase the limit? I can't seem to find it on the Global
Settings.

This can be easily changed from GUI, in Global Settings. Check

Hi Prachi and especially Ryan,
Many thanks! Managed to find the option on Global Settings and change view
to "Hypervisor Capabilities" as per Ryan's advice! Have changed the value
under KVM, default to a higher value.
Cheers.

Actually, this functionality exists in the UI, too.
In Global Settings, be sure to select view as "Hypervisor Capabilities"
instead of "Global Settings."
Then, raise {KVM, default} to a higher value.

Hi Indra,
You need to call the updateHypervisorCapabilities API and set the 'maxguestslimit' to a new value for the KVM hypervisor.
The listHypervisorCapabilities API will let you know the necessary ID of the capability to be updated.
