[ovirt-users] corrupted hosted engine

Hi, It looks like after host restart my hosted engine VM is not accessible any more. The storage is glusterfs. The gluster volume is healthy. The VM status is: {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"} hosted-engine --console The engine VM is running on this host Connected to domain HostedEngine Escape character is ^] error: internal error: cannot find character device <null> I tried to boot it from cdrom by changing vm.conf file and I'm not sure if the syntax is correct: 1. I removed bootOrder:1 from the index:0 device devices={index:0,iface:virtio,format:raw,address:{type:pci,slot:0x07,bus:0x00,domain:0x0000,function:0x0},volumeID:8d823e33-4260-4004-a468-cf477d7b1f5b,imageID:41342181-5c8f-4544-878b-44fdaa40dddc,readonly:false,domainID:beb954e7-61b7-4437-bd21-4b268e1a26e5,deviceId:41342181-5c8f-4544-878b-44fdaa40dddc,poolID:00000000-0000-0000-0000-000000000000,device:disk,shared:exclusive,propagateErrors:off,type:disk} 2. in index:2 device I addedd bootOrder:1 and path to the iso image: devices={index:2,iface:ide,shared:false,readonly:true,bootOrder:1,deviceId:8c3179ac-b322-4f5c-9449-c52e3665e0ae,address:{controller:0,target:0,unit:0,bus:1,type:drive},device:cdrom,path:/opt/iso/CentOS-7-x86_64-DVD-1804.iso,type:disk} The outcome is the same - no console connection. Now I also get: hosted-engine --vm-start Command VM.getStats with args {'vmID': '1e3aa9cf-8708-40a0-bc86-1127df01047a'} failed: (code=1, message=Virtual machine does not exist: {'vmId': u'1e3aa9cf-8708-40a0-bc86-1127df01047a'}) Unfortunately I do not have any backup. Is there a way to redeploy hosted engine and import current configuration or any other way to fix it?
