Hello guys!

I recently noticed, that when I live migrate VMs to other servers in the same cluster, that the VM reboots. In my view this should not happen, or am I wrong?

We use CEPH for our storage and OpenNebula 5.4.1 with KVM

Thank you all!

Kind regards

Dominique

Hi Dominique,

this shouldn’t happen, live migrations transfer the running virtual machine and memory state to the other host where it continues. Can you please provide what OS/kernel version and KVM version is running the host and what OS/kernel is running in the guest?

Best regards,

Hi Vlastimil

I tried to reproduce now but It worked all like a charm now  
Is it possible that this happend because I was updating the servers to the newest version?  
So I live migrated all VMs from the server which was getting updated to a server which was already updated.

Because right now, all servers are on the same version and now live migration works without reboot.

However here are the infos you required:

OS (Host):

```
# lsb_release -a
No LSB modules are available.
Distributor ID:	Devuan
Description:	Devuan GNU/Linux 2.0 (ascii)
Release:	2.0
Codename:	ascii

# uname -a
Linux server 4.9.0-4-amd64 #1 SMP Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux

```

And here the kvm infos

```
# kvm -version
QEMU emulator version 2.8.1(Debian 1:2.8+dfsg-6+deb9u3)
Copyright (c) 2003-2016 Fabrice Bellard and the QEMU Project developers

```

The guest systems were different kind of (CentOS / Debian, persistent / not persistent)

Thank you very much Vlastimil
