how we can avoid conflict if using two separate cs env with common resources
Hello,
I have setup two CS env but both are using same infrastructure
.Now i am getting a lot of conflict problem due to separate db
Env1- CS1 --> DB1
Env2- CS2 --> DB2
*Conflict scenario :*
1) during vm creation it was found that vm-id had been conflicted in xen
host
2) during template creation it was found that template has been conflicted
in secondary storage
eg.
created one template from CS1 and one template from CS2 .Now
both template created vhd file in one folder.
. $ cat 2/204/
160eaf67-a20a-37f0-83c9-326915990efc.vhd
392b128e-0b4c-3a8b-9bf5-3488dd026816.vhd
template.properties
My concern is
1) how we can avoid conflict ?
2) is there any option for reserved resources and
avoid conflict ?
--
Thanks and Regards,
cpm

Hi chandraprakash,
Yes, there is a process that remove any VMs not managed by cloudstack on
hypervisors. As far as I know you can't disabled that process.

thanks for replied to me.
I need one more help .is there any process/scheduler is running in CS
which delete the vms from hyper-wiser( xen host) if that vms info are not
available in database.
if it is true, then how we can disable this service/scheduler for some
time.

if you want to run multiple CloudStack env using same networks but
different databases and different version of CloudStack you have to use
seperate secondary storage, at least it have to have a different mountpoint
if they use the same nfs server , ex: /export/env1, /export/env2
Also two seperate CloudStack env cannot managed the same hypervisor server.
so you will have to have 2 hypervisors hosts, they could be VM on a
physical servers if you only have one physical server.
On the network side, then you need to pay attention so both envs does not
conflict with DHCPs and Vlans,
