Configuring Reservations and Reservation Policies
A vRealize Automation reservation can define policies, priorities, and quotas that determine machine
placement for provisioning requests. Reservation policies restrict machine provisioning to a subset of
available reservations. Storage reservation policies allow blueprint architects to assign machine volumes
to different datastores.
Reservations
You can create a vRealize Automation reservation to allocate provisioning resources in the fabric group to
a specific business group.
For example, you can use reservations to specify that a share of the memory, CPU, networking, and
storage resources of a single compute resource belongs to a particular business group or that certain
machines be allocated to a specific business group.
Note Note: Storage and memory that are assigned to a provisioned machine by a reservation are
released when the machine to which they are assigned is deleted in vRealize Automation by the Destroy
action. The storage and memory are not released if the machine is deleted on the vCenter Server.
You can create a reservation for the following machine types:
n
vSphere
n
vCloud Air
n
vCloud Director
n
Amazon
n
Hyper-V
n
KVM
n
OpenStack
n
SCVMM
n
XenServer
n
Microsoft Azure
You can configure security settings for the virtual machines to be provisioned by specifying information in
a reservation, blueprint, or guest agent script. If the machines to be provisioned requires a guest agent,
you must add a security rule that contains that requirement to the reservation or the blueprint. For
example, if you use a default security policy that denies communication between all machines, and rely
on a separate security policy to allow communication between specific machines, the guest agent might
be unable to communicate with vRealize Automation during the customization phase. To avoid this
problem during machine provisioning, use a default security policy that allows communication during the
customization phase.
