Subject Re: Host with running VMs question.
Date Thu, 13 Nov 2014 05:26:57 GMT
Hi Clark,

You cannot remove host while running VMs on your cloudstack. I am not sure 
what you had done to reinstall cloudstack-agent and cloudstack database. If 
you had local storage disk corruption then it will affect all your running 
VMs ROOT disks and DATA disks.

If you will re add the host forcefully then stilll VMs will show destroyed 
state again. You can manually change VMs state on database itself.

Thank You.
