Operating System Profiles

In Sunstone you can quickly flavor a VM template by using an Operating System Profile, which will pre-fill part of the template for you. By default, Sunstone ships with a “Windows Optimized” profile which contains some basic Windows-specific optimization settings.

Defining a Profile

Navigate to the profiles directory
By default found in etc/one/fireedge/sunstone/profiles.
Create a new YAML file
Name your profile by defining a new .yaml file
Note
The filename is used to identify the profile in Sunstone. The filename is sentence-cased and all _ characters are displayed as spaces. For example, windows_optimized.yaml becomes Windows Optimized.
Configure the profile
Define the profile according to the Operating System Profiles schema.
Important
All values are case sensitive
Here’s an example of a profile that fills in the name of the VM template, the CPU & memory configuration, and sets up the backup strategy.
```
---
# basic_profile.yaml
"General":
  NAME: "Example profile"
  CPU: 4
  VCPU: 4
  MEMORY: 8
  MEMORYUNIT: "GB"

"Advanced options":
  Backup:
    BACKUP_CONFIG:
     MODE: "INCREMENT"
     INCREMENT_MODE: "CBT"
     BACKUP_VOLATILE: "Yes"
     FS_FREEZE: "AGENT"
     KEEP_LAST: 7
```
The profile can then be saved and accessed in Sunstone from the first step in the VM Templates Create/Update dialog:

Important

Sunstone also ships with a base.template file (found in the default profiles directory), which includes examples for majority of the inputs for a VM template. This base template should only be used as a reference when creating new profiles and not directly used as-is.

Profile Chain Loading

It’s also possible to chain-load profiles by referencing one profile from another. This allows you to combine snippets of profiles together more efficiently, combining different optimizations for specialized use cases.

Take for example the default Windows profile that ships with Sunstone:

---
# Windows profile
"General":
  NAME: "Optimized Windows Profile"

"Advanced options":
  OsCpu:
    OS:
      ARCH: X86_64
      SD_DISK_BUS: scsi
      MACHINE: host-passthrough
      FIRMWARE: BIOS
    FEATURES:
      ACPI: "Yes"
      PAE: "Yes"
      APIC: "Yes"
      HYPERV: "Yes"
      LOCALTIME: "Yes"
      GUEST_AGENT: "Yes"
      VIRTIO_SCSI_QUEUES: "auto"
      VIRTIO_BLK_QUEUES: "auto"
      # IOTHREADS:
    CPU_MODEL:
      MODEL: "host-passthrough"
        # FEATURES:
        # - Tunable depending on host CPU support
        # -
    RAW:
      DATA: |-
        <features>
          <hyperv>
            <evmcs state='off'/>
            <frequencies state='on'/>
            <ipi state='on'/>
            <reenlightenment state='off'/>
            <relaxed state='on'/>
            <reset state='off'/>
            <runtime state='on'/>
            <spinlocks state='on' retries='8191'/>
            <stimer state='on'/>
            <synic state='on'/>
            <tlbflush state='on'/>
            <vapic state='on'/>
            <vpindex state='on'/>
          </hyperv>
        </features>
        <clock offset='utc'>
          <timer name='hpet' present='no'/>
          <timer name='hypervclock' present='yes'/>
          <timer name='pit' tickpolicy='delay'/>
          <timer name='rtc' tickpolicy='catchup'/>
        </clock>
      VALIDATE: "Yes"

Now say you want to combine this profile with the basic profile from the previous section. Now you just add the OS_PROFILE attribute to the basic profile’s configuration and reference the other profile from it:

Note

The OS_PROFILE value being referenced should match the one on disk exactly, excluding the .yaml extension

---
# basic_profile.yaml
"General":
  NAME: "Example profile"
  OS_PROFILE: "windows_optimized"
  CPU: 4
  VCPU: 4
  MEMORY: 8
  MEMORYUNIT: "GB"

"Advanced options":
  Backup:
    BACKUP_CONFIG:
     MODE: "INCREMENT"
     INCREMENT_MODE: "CBT"
     BACKUP_VOLATILE: "Yes"
     FS_FREEZE: "AGENT"
     KEEP_LAST: 7

Sunstone now sequentially loads each profile and applies them on top of each other. This means that if two fields modify the same values, e.g., NAME, the last profile to modify that field will be used.
