Hi Kiran, For backward compatibility, the `considerlasthost` is default to true if it is not set.
The issue seems to be fixed in 4.19.1.0 by https://github.com/apache/cloudstack/pull/9037 However, I cannot find the changes in the code base of 4.19 branch. https://github.com/apache/cloudstack/blob/4.19/server/src/main/java/com/cloud/deploy/DeploymentPlanningManagerImpl.java#L449-L453 It looks like something is wrong during the merge of the 4.18 to 4.19 branch. cc @Daan Hoogland <daan.hoogl...@shapeblue.com> @suresh.anapa...@shapeblue.com <suresh.anapa...@shapeblue.com> -Wei On Fri, Jan 10, 2025 at 7:58 AM Kiran Chavala <kiran.chav...@shapeblue.com> wrote: > Hi Eric > > I am not hitting the issue on the latest 4.20 release of cloudstack > > For a normal end user, it doesn’t consider the last host to start the > virtual machine > > the startVirtualMachine Api call has the parameter “considerlasthost” for > the admin user > > > https://cloudstack.apache.org/api/apidocs-4.20/apis/startVirtualMachine.html > > For a normal user there is no parameter “ considerlasthost” , the > deployment planner picks up the available host > > Normal user > > (localcloud2) 🐱 > start virtualmachine > bootintosetup= clusterid= filter= hostid= id= > podid= > > > Regards > Kiran > > From: Eric Green <eric.lee.gr...@gmail.com> > Date: Friday, 10 January 2025 at 4:05 AM > To: users@cloudstack.apache.org <users@cloudstack.apache.org> > Subject: A possible bug in instance start for end users when a host is > deleted > This appears to me to be a bug.
