VM Settings
Hi,
I use cloudstack with KVM and I'm trying to add new information to the XML
file of one of my VM's, to be more precise I want to add a new disk to it
without using the Storage function.
What I tried so far was using the VM Settings and extraconfig to pass on a
URL with the configuration of my disk (which is actually a LUN) but I'm not
sure how that works and the Documentation did help me much. So as a simpler
question I want to know how I can add new stuff to a VM's XML file through
Cloudstack.
I added a value to
allow.additional.vm.configuration.list.kvm
and used this value ("disk" in this case) as my name when creating a new
Setting in the VM and then put "extraconfig=myURL" in the value for the VM
Setting. Is this right?
I'm not sure what I should put as value in this Global Setting and not sure
if it matters what I put as name in the VM Settings.
If you could explain to me how that works or if there's better
documentation or a video tutorial on VM Settings cause the official one did
not help me.
Thank you!!

Re: Problems with KVM HA & STONITH

Couple of questions if you have the time to respond - 1) this article seems to suggest a reboot or powering off a host will end result in the VMs being migrated and this was on CS v 4.2.1 back in 2013 so does Host HA do something different 2) Whenever one of my two nodes is taken down in testing the active compute nodes HA status goes from Available to Ineligible.

The management server (without host-HA) cannot tell what happened to the host. It cannot tell if there was a failure in the agent, loss of connectivity to the management NIC or if the host is truly down. In the first two scenarios, the guest VMs can still be running perfectly well, and to restart them elsewhere would be very dangerous. Therefore, the correct thing to do is - nothing but alert the operator. These scenarios are what Host-HA was introduced for. Wrt to STONITH, if no disk activity is detected on the host, host-HA will try to restart (via IPMI) the host. If, after a configurable number of attempts, the host agent still does not check in, then host-HA will shut down the host (via IPMA), trigger VM-HA and mark the host as in-maintenance. paul.an...@shapeblue.com www.shapeblue.com<http://www.shapeblue.com> [http://www.shapeblue.com/wp-content/uploads/2017/06/logo.png]<http://www.shapeblue.com/> Shapeblue - The CloudStack Company<http://www.shapeblue.com/> www.shapeblue.com Rapid deployment framework for Apache CloudStack IaaS Clouds.

Thanks for the response. I think I am not understanding how it was meant to work then. My understanding was that the manager used ipmitool to just keep querying the compute nodes as to their status so I assumed it didn't matter how you shut the node down, once it was down the manager would get no response and mark it as down (which it does).

But I couldn't find a way how we can achieve HA with the host. What will happen to the VM's in a host which is in halted state. Can you explain how the out of management help you in this case. I couldn't trace out much from the logs. Regards Victor On 08/07/2017 12:33 AM, Rohit Yadav wrote: Victor, Which proposed features do you want to know, if they are covered with ipmi oobm?

KVM+HA
Hello Guys, I am facing the same issue that mentioned in the following url . - https://issues.apache.org/jira/browse/CLOUDSTACK-3535 - When the host is put in maintenance mode , then ha enabled VM's are automatically migrated to available host. But when the kvm host is down, no HA is done. The vm's are still down until I put the host node back up. I have tried everything like the following. = 1, system VM's and client vm's are created in shared storage 3, Added ha.tag host tags 2, Created host by adding ha tag 3, Created VE's in Ha enabled host with ha enabled service offering Do you guys have successfully tested Ha. I am really stuck at this part. Regards
Re: KVM hypervm and HA
Hello, Thanks for the update. When a single vm in "hypervm1" is stopped or down, it gets automatically started in the second vm. But when the entire hypervm1 server is down completely, the vm' inside it is not getting started in the secondary "hypervm2". Is the feature is version specific.
