Thanks Shiva !! With around of adding : model='pci-ohci' to usb controller helps to resolve migration error. Before applying workaround: ---------------- root@lotkvm:~# virsh dumpxml lotg9|grep usb <controller type='usb' index='0'> <alias name='usb'/> root@lotkvm:~# root@lotkvm:~# virsh migrate --live --domain lotg9 qemu+ssh://10.33.32.222/system --verbose --undefinesource --persistent --timeout 60 --unsafe 2>&1 Migration: [100 %]error: operation failed: job: unexpectedly failed After applying work around: ------------------------- root@lotkvm:~# virsh dumpxml lotg9|grep usb <controller type='usb' index='0' model='pci-ohci'> <alias name='usb'/> root@lotkvm:~# root@lotkvm:~# virsh migrate --live --domain lotg9 qemu+ssh://10.33.32.222/system --verbose --undefinesource --persistent --timeout 60 --unsafe 2>&1 Migration: [100 %] root@lotkvm:~# Does this need to be documented in Ubuntu release notes ? Thanks, Manju == Comment: #11 - Shivaprasad G. Bhat <shiva...@in.ibm.com> - 2017-01-02 02:31:00 == Hi Manju, Chandan, Yes, I think this should be documented as its likely to happen and because this is seen only on PPC without a documentation it is hard to figure out why its happening.
