Hosted-Engine mount .iso file CLI

I have a hosted engine setup that when I ran the system updates for it, and it will not boot. I would like to have it boot from a rescue CD image so i can fix it i have copied the /var/run/ovirt-hosted-engine-ha/vm.conf to /root and modified it however i cannot seem to find the exact options to configure the file for .iso my current settings are devices={index:2,iface:ide,shared:false,readonly:true,deviceId:8c3179ac-b322-4f5c-9449-c52e3665e0ae,address:{controller:0,target:0,unit:0,bus:1,type:drive},device:cdrom,path:,type:disk} How do i change it to boot from local .iso. Thanks Any help would be most appreciated.

Did you set global maintenance mode at update time? If not, ovirt-ha-agent could try to restart the engine VM for HA reasons in the middle of the update with potentially dangerous results.

Hi, you can add 'bootOrder:1' and the path to your iso image after 'path:' on your cdrom device line in a local copy of vm.conf. You have also to remove 'bootOrder:1' from the disk device. So you can try starting the VM with hosted-engine --vm-start --vm-conf=/your/custom/vm.conf Good luck
Thanks
