Hi, few days ago I have installed Opennebula system with two hosts…after downloaded the ttylinux image from app repository, I have tried to execute multi instances of image on same hosts. The first instance run regularly but the follow stay pending… For convenience I have disabled one host … and after lunch the first instances the host status get in error: ID NAME CLUSTER RVM ALLOCATED\_CPU ALLOCATED\_MEM STAT 5 HostMasterFews default 0 0 / 800 (0%) 0K / 15.6G (0%) dsbl 7 NebulaKVM default 1 50 / 800 (6%) 128M / 15.7G (0%) err and the error is: Wed Feb 7 11:15:17 2018 : Error monitoring Host NebulaKVM (7): ../../vmm/kvm/poll:228:in `round': wrong number of arguments (1 for 0) (ArgumentError) from ../../vmm/kvm/poll:228:in `get\_cpu\_info’ from ../../vmm/kvm/poll:226:in `each' from ../../vmm/kvm/poll:226:in `get\_cpu\_info’ from ../../vmm/kvm/poll:132:in `get_all_vm_info' from ../../vmm/kvm/../lib/poll_common.rb:99:in `print\_all\_vm\_template’ from ../../vmm/kvm/poll:531 ERROR MESSAGE --8\<------ Error executing poll.sh ERROR MESSAGE ------\>8– now … why this error jump out? why the second instance remains pending? I have tried to ask in support forum without succes Best regards! ---
