Re: [Xen-API] exception MEMORY_CONSTRAINT_VIOLATION

[Marco Sinhoreli <msinhore@xxxxxxxxx>]

Hi Jonathan,

I'm using the python xenapi. Above the source code for setup VM memory
dynamic and static:

<code>
        [...]
        # Cloning the template
        vm = self.master.VM.clone(template_ref, label)

        # Configuring the VM memory

        memory_size = str(memory_size * 1024 * 1024)
        self.master.VM.set_memory_dynamic_max(vm, memory_size)
        self.master.VM.set_memory_dynamic_min(vm, memory_size)
        self.master.VM.set_memory_static_max(vm, memory_size)
        self.master.VM.set_memory_static_min(vm, memory_size)

        # Configuring the network interface
        self.__create_vlan_if_not_exists(host, master, vlan, 'eth0',
'Kickstart Install VLAN')
        self.__configure_network_interface(vm, host, master, vlan, 'eth0', '0')
        [...]
</code>

Cheers,
