Hi René, Thanks for bringing it up. I talked to Rohit and he pointed me towards: https://issues.apache.org/jira/browse/CLOUDSTACK-7994
It seems it is done on purpose as a fix. I think we should discuss this on the dev-list ;-) Regards, Remi On 03 Jun 2015, at 08:44, ilya <ilya.mailing.li...@gmail.com<mailto:ilya.mailing.li...@gmail.com>> wrote: Rene Are you running Advanced Shared Zone?

Environment: Hypervisor: VMware vsphere 5.1 CloudStack: 4.5.1 (upstream) Networking: Advanced VR: systemvm-4.5 (shapeblue) Problem: We tested the VM sync which worked as expected for VMs. But after we migrated (computing only) a VR, the VR gets rebooted in every case and we see this in the logs: https://gist.githubusercontent.com/resmo/ce026c49373d54eb24e6/raw/1bf7d22c26fa07000cae5ab191e6a76d4b189fa7/gistfile1.txt Expected: VRs should not reboot after migration. This would be a blocker for us. Could anyone confirm this? Yours René
