<html><body><div style="color:#000; background-color:#fff; font-family:arial, helvetica, sans-serif;font-size:10pt"><div>Hello,</div><div>so, now I gathered some information about the workflow of the cold migration and found out that ACPI should be correctly configured for libvirt to suspend the VM and resume it afterwards.</div><div>I tried it first with a debian lenny VM, but unfortunately had no luck making it work as expected. Until before the migration I am able to ping this VM, but as soon as the migration starts I receive a "Destination Host Unreachable" and it doesn't heal itself after some time either. Strangely, "acpi", "acpid" and "acpi-support" are all installed...and "pm-utils" as well, but still no luck! <br></div><div>Another strange thing is, that the command "acpi -V" gives me back following result:</div><div><br></div><div>No support for device type: power_supply</div><div>Cooling 0: Processor 0 of 0</div><div><br></div><div>I also
tried it with an Ubuntu VM, but unfortunately with the same results. Could it be that my cluster-PCs just don't have the needed hardware for the ACPI-functions, which is why the VMs also aren't able to do that?</div><div><br></div><div>Of course I have set FEATURES = [ acpi = "yes" ] in my template...</div><div>Any ideas on where I should look next? Thanks!</div><div><br></div><div>Regards</div></div></body></html>
