VM Scheduling

Overview

---

Virtual Machine (VM) Creation Wizard is a HyperCloud™ Platform (HCP) feature that lets you schedule your VM. You can define the VM Start and Stop schedule if you have a definite work pattern or you want to reduce your cloud costs. To specify a VM start and stop schedule:

1. Login to your HCP account.

2. Navigate to Service Orchestration > Services > VMs > VM Creation Wizard > Advanced tab > Select the Define a VM Start and Stop Schedule.

You can schedule a VM in three ways:

• Recurrence Start VM Schedule
• Specific Start VM Schedule
• Advanced (Via Quartz Cron Expression) 

Notes:

• You can specify the VM Start and Stop Schedule for a VM that's created before. However, you will not be able to change a schedule once you've specified it.

• You can view Scheduled VMs in a separate 'Scheduled' tab. 

Recurrence Start VM Schedule

---

Select Recurrence Start VM Schedule if you want to implement recurring Start and Stop Schedules for your VM. Once you choose the VM Schedule, you'll need to select the values for:

• Start and End Date for your Schedule.

• Pick the recurrence or frequency for Starting and Stopping a VM.

  • You can choose from Daily, Weekly or Monthly recurrences.  

• Select the VM Start Time.

• Select the validity period for the VM. Post this period, your VM will be terminated. 

Specific Start VM Schedule

---

If you want to schedule the VM Start and Stop time for a specific time, use the Specific Start VM Schedule. This setting is similar to a VM lease period. Once you select this setting, set the Start and Stop Date for your VM.

Advanced (Via Quartz Cron Expression) 

---

You can customize your VM Start and Stop Dates.  

This setting is similar to the Quartz Cron syntax with some minor differences. To customize your VM Start and Stop Schedule, enter values for these parameters and separated by whitespaces: 

MINUTE HOUR DOM MONTH DOW YY

We've listed the details for the syntax in the table below:

 

Field Name	Description
MINUTE	Minutes within the hour (0–59)

Day-of-Month	The day of the month (1–31)

Day-of-Week	The day of Week or you can specify multiple days (SAT,SUN, MON, TUE.. )
