reserved CPU?
Hello
I am unable to start any routers due to this error
Host does not have enough reserved CPU available, cannot allocate to this host.
I cannot find any setting to adjust the reserved CPU for a host - these have plenty
Can someone point me in the right direction please
CS 4.13.1.0 - KVM hosts

Hi Adam,
try reducing the global setting: capacity.skipcounting.hours
Without the logs, there's not much we can conclude. Usually, if you are
i.e. FULL in terms of CPU capacity (i.e. reached the limit above which no
new VMs can be deployed) - then when you STOP an existing VM, host will
reserve the amount of CPU used by that stopped VM - so that you can
immediately/within the " capacity.skipcounting.hours " start it again - but
it will not allow you to deploy new VMs even while that existing VM is
stopped.
Hope that helps,

That setting seems fine, I can start an instance.
I cannot start a system VM due to reserved capacity?
Thanks

Hi,
From "Home > Infrastructure > Clusters > your_cluster" click on "Settings"
tab. In search bar type "cpu" and you will see a list of variables that controls CPU usage and allocation in your cluster.
You can "increase cpu.overprovisioning.factor" or change "cluster.cpu.allocated.capacity.disablethreshold"

Hi,
From "Home > Infrastructure > Clusters > your_cluster" click on "Settings"
tab. In search bar type "cpu" and you will see a list of variables that
controls CPU usage and allocation in your cluster.
You can "increase cpu.overprovisioning.factor" or change
"cluster.cpu.allocated.capacity.disablethreshold"
