How to start a guest VM on different host?
Dear all, When I stop and then start back a guest VM, CloudStack will try to start it back on the same hypervisor host where the VM was hosted previously. Is it possible for me to start a guest VM on a specific other hypervisor host? Looking forward to your reply, thank you. Cheers.

Hi, Try using host tagging feature supported by CloudStack. I am not sure whether the tagging will be applicable for already deployed vms. You can give a try. -Sanjeev -Original Message- From: Indra Pramana [mailto:in...@sg.or.id] Sent: Monday, September 22, 2014 7:57 AM To: dev@cloudstack.apache.org; us...@cloudstack.apache.org Subject: How to start a guest VM on different host?

If you are root admin, you can use startVirtualMachine api call with hostId parameter https://cloudstack.apache.org/docs/api/apidocs-4.3/root_admin/startVirtualMachine.html -Original Message- From: Sanjeev Neelarapu [mailto:sanjeev.neelar...@citrix.com] Sent: Monday, September 22, 2014 9:44 AM To: us...@cloudstack.apache.org; dev@cloudstack.apache.org Subject: RE: How to start a guest VM on different host?

Hi Sanjeev and Anshul, Good day to you, and thank you for your replies. Sanjeev - yes, host tagging works by creating a new service compute offering with the host tag, change the guest VM's service compute offering and start the guest VM. I have just tested earlier. However, this will remove the HA functionality since if that particular host is down, the guest VM will not be started on other available hosts because of the host tag, so this is not the best solution IMHO. Anshul - thanks for the info, will try this. If this works, then this would be the best solution. Thank you.
