Subject RE: Reimage Instance
Date Fri, 04 Jan 2013 21:52:47 GMT
Hi,

It is not currently supported, but have no clue whether it will be supported later or not.
CS is using linked in clones so you just cannot simply replace the template the VM is based
on because the VMs ROOT volume depends on it.
To "re-image" basically you'd need to destroy the VM with its disks then re-deploy it with
the new template but because it is a new VM new IP will be allocated for it.
If you want the new VM with a specific (previous) IP address you'll need to manually edit
the database.

Regards

I have used every public cloud out there and everyone will allow a reimage of a VM from a
template. Is this a feature that will fundamentally not be supported Cloudstack, or just one
that isnt supported currently?

Hi,

I'm using advanced vlan isolated networking with dhcp.
For me the internal IPs do not matter as the public IP belongs to the account and the virtual
router will sort out the rest.

Via the GUI you cannot preserve IPs but manually via the database you can change what IP belongs
to what VM.

My recovery procedure is to deploy a brand new VM, re-attach the data volume to it and update
the firewall/static-nat rules if any to the new VM.

How do you preserve hostname and IP address if you want to spin a box up from scratch again....assuming
you are using advanced networking and dhcp?

Hi,

I don't think there is.
You can change the template of your VM by manually editing the database and then shut it down
and restart it.
This way at the next start CS will re-deploy the new template for the VM and start it.

Please be aware this is not recommended in production due to this method will confuse the
storage clean-up scripts and will kill your live VM in case the old template it was based
on no longer required.
It is always recommended to create a new VM instance with the new template.

Subject: Reimage Instance

Is there a way through the Cloudstack UI, to respin an already active instance with a new
template? I see a way in the API, but nothing in the UI.
