<br>
it is great to know, is it related to the improved monitoring in ONE? I am getting ready for trials of ONE 4.6.<br>
<br>
We are using shared_lvm driver, so I would like to know if the new LVM driver is compatible with it? Or I can expect some major issues? I havent had enough time to check..<br>
<br>
Thanks Milos<br>

Hi,<br>
<br>
Issues with delete and shutdown have been greatly improved in<br>
OpenNebula 4.4+, I would recommend upgrading as far as possible.<br>
<br>
Best,<br>

We have also seen this behavior in OpenNebula 3.2.<br>
It appears that the failure mode occurs because the onevm delete<br>
(or shutdown or migrate) doesn't correctly verify that the virtual machine<br>
has gone away.<br>
It sends the acpi terminate signal to the virtual machine<br>
but if that fails, the VM will keep running. There is no<br>
signal sent to libvirt to kill the machine regardless.<br>
OpenNebula<br>
deletes the disk.0 from underneath it but that doesn't stop<br>
the vm from running, it stays running on the deleted file handle.<br>
<br>
On the plus side, I once was able to recover the full disk image<br>
of a VM that shouldn't have been deleted, that way, by going<br>
to the /proc file system and dd'ing from the still-open file<br>
handle of the process.<br>
<br>
We've written a set of utilities to check the consistency<br>
of the leases database with what is actually running on the cloud,<br>
and alert us if there are any differences.<br>

Hi all,<br>
<br>
We are using Opennebula 4.2 system with several hosts ( KVM +<br>
network storage) .<br>
<br>
Recently we have discovered, by having disk r/w issues on a VM, that<br>
after a delete - recreate action, specific VM is running on two<br>
different hosts: the old placement host and the new placement host.<br>
<br>
We are using the hooks system for host failure and a cron job at 5<br>
minutes which is (re)deploying pending machines on available running<br>
hosts.<br>
<br>
By checking oned log files we couldn't find any abnormal behavior<br>
and we are stuck.<br>
<br>
Please guide us to find the root cause of this issue if is possible.<br>
<br>

Thank you,<br>
