heat resume Vms and run from SNAPSHOT: I have a stack of VMs (nova servers). The commands i execute are the following: openstack stack create openstack stack suspend openstack stack snapshot create At this point stack_state is in status SNAPSHOT_COMPLETED and vms_state is in status SUSPENDED How can i resume stack, with VMs be active and in Running state, LAUNCING the SNAPSHOTTED image. I can't resume the stack, because the VMs are in SNAPSHOTTED state. How Heat deals with it? How can you resume a stack with status SNAPSHOT_COMPLETED and VMs suspended to vm_state = unning for all the VMs of the stack

openstack heat multi tenant scenario
by Charls D. Chap 11 Oct '17

Scenario: -DomainA (TenantA, TenantB) -TenantA(userA) -TenantB(userB) - A template which start OS:NOVA:SERVERS 1. Is it possible two run simultaneously the same openstack stack create command? 2. a. how can i specify that i want, in the first case, the VMs of the stack, beloging to TenantA and in the second case to TenantB b. for the OS::NOVA::SERVER as fas as i can see there is no such property to Distinguish project names c. I want to achieve something like this openstack stack create "mystack" for TenantA openstack stack create "mystack" for TenantB openstack server list for TenantA VM1 RUNNING VM2 RUNNING .... openstack server list for TenantB VM1 RUNNING VM2 RUNNING .... So THE SAME VMs for both Tenants! 3. In the end, how is multi-tenancy achieved? So far, I have achieved it, by having two different stack names, tenantA and tenantB correspondingly, which take as input the same template, with the same parameters.
