Hi team ,

Thank you all for your prompt supports .  
While testing Opennebula 5 beta , i have found some serious boot problems .

1 . I have rebooted my opennebula host while all VM’s are powered on . But after boot back, sunstone GUI shows all vm’s are power on . But actually all machines are in power off state . Because of that I forced to run `Recovery > Delete` .

2 . I took snapshot of one machine and got success . After shutdown and power on that vm , snapshot’s are gone . I thing this issue is also stick with current stable release 4.14 .

Is it bug?

Regards

Did you wait a bit for the status update? The process is as follows:

1.- Host goes down  
2.- Monitor time expires for the host  
3.- OpenNebula tries to restart the monitoring probes  
4.- Restarting fails and VMs goes to unknown  
5.- OpenNebula periodically tries to recover the host. Eventually it’ll be  
up and probes restart  
6.- No information about the VMs is found in the monitor info for the host.  
VMs are moved to poweroff

This steps takes time, the timeouts can be tuned though

It is a current limitation of libvirt. The snapshots are kept in the image  
but once you “undefine” the domain (e.g. to poweroff or migrate) the  
snapshots are gone. There is a flag in oned.conf to modifiy this behavior,  
so as soon as this works in libvirt snapshots will not be cleaned.

Can you send oned.log, at least the messages related to beta.cloud…

BTW, is this the last 5.0 release?

Hi ,

While checking bug report about vm snapshot , i found below link and its closed .

[http://dev.opennebula.org/issues/3740](http://dev.opennebula.org/issues/3740)

In the VM\_MAD attribute, in oned.conf

```auto
VM_MAD = [
    NAME = "kvm",
    SUNSTONE_NAME = "KVM",
    EXECUTABLE = "one_vmm_exec",
    ARGUMENTS = "-t 15 -r 0 kvm",
    DEFAULT = "vmm_exec/vmm_exec_kvm.conf",
    TYPE = "kvm",
    KEEP_SNAPSHOTS = "no",
    IMPORTED_VMS_ACTIONS = "terminate, terminate-hard, hold, release,
suspend,
        resume, delete, reboot, reboot-hard, resched, unresched,
disk-attach,
        disk-detach, nic-attach, nic-detach, snap-create, snap-delete"
]

```

But note that this may not be supported by the hypervisor.
