True. Maybe it's too restrictive, but you can disable VCPU for end users
with the vm restricted attributes [1] and set a default in the driver [2].

Re: [one-users] Quota for vCPU

[Ondrej Hamada]

Some sort of vCPU quota might be good idea in case the users are allowed to 
create their own templates. They are able to rise the count of vCPU sky high if 
their app goes too slow. In KVM the vCPU presents the number of threads the 
virtual machine could use. Setting too many vCPUs for several VMs on a same 
host might kill the hypervisor because of the context switching.

No, it's not possible, but it does not matter because the vCPU is virtual. It 
does not mater if a user defines 1 or 10 vCPU, the amount of physical host cpu 
assigned to the VM is determined by the CPU attribute.

No, it's not possible, but it does not matter because the vCPU is virtual.
It does not mater if a user defines 1 or 10 vCPU, the amount of physical
host cpu assigned to the VM is determined by the CPU attribute.

[one-users] Quota for vCPU

[Mateusz Skała]

Hi,
It is possible to set up quota for vCPU? I see only quota for CPU.
