Subject Re: How to start a guest VM on different host?
Date Mon, 22 Sep 2014 04:42:32 GMT
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.
