Hi all

We're using the http API to manage our VMs. We can set the number of VCPUs of a running VM with set_VCPUs_number_live, but if the VM is rebooted, the change is lost.
I know I must use VCPUs_at_startup and VCPUs_max to fix the number of VCPUs on a halted VM, but sometimes I cannot shutdown a VM to change those values...
Does anyone know a workaround for this?
Thanks a kind regards
