Our lab machines tend to have small memory sizes. When we do our testing, we often ‘cheat’ by allocating less RAM for Nuage VMs that we spin up on hypervisors. This is *Not* acceptable in a production environment, but can be useful in a PoC or lab/test setup.

Modifying the RAM allocated for the Nuage VMs is optional. By default, the proper memory sizes are used. You can control the amount using the common.yml file in your deployment:

##### PoC Parameters

# < VSD Disk Size >
# Amount of VSD disk space to allocate, in GB. Valid only for KVM deployments. Note: Changing the default value is not a supported configuration.
#
# vsd_fallocate_size_gb: 285

# < VSD RAM >
# Amount of VSD RAM to allocate, in GB. Valid only for KVM deployments. Note: Changing the default value is not a supported configuration.
#
# vsd_ram: 24

# < VSC RAM >
# Amount of VSC RAM to allocate, in GB. Valid only for KVM deployments. Note: Changing the default value is not a supported configuration.
#
# vsc_ram: 4

# < VSTAT RAM >
# Amount of VSTAT RAM to allocate, in GB. Valid only for KVM deployments. Note: Changing the default value is not a supported configuration.
#
# vstat_ram: 16

The amounts of RAM shown are the default values. To set a lower value, uncomment the appropriate lines and set your own amount. Warning: VSD and VCIN will refuse to install if you set their values to less than 8 GB and 12 GB, respectively. Nuage components may not operate properly if they don’t ahve enough memory.

PoC Only!

In our lab, we use:

vsd_ram: 8
vstat_ram: 2
vsc_ram: 6
vcin_ram: 12
