[ovirt-devel] Re: VM export: task stucked

Hi all, everyday at 01:00 AM we perform a daily backup on many VMs hosted in multiple hosts (all with oVirt 4.3) using a custom sciprt written in python3 (using SDK) and everything works "almost" fine. There is one single VM (Windows Server 2016) with a disk of 600 GB (the real disk usage is about 150 GB) hosted on a single node that has a strange behaviour. 1) The export start after a few seconds of the execution of the script, we use "vm_service.export_to_path_on_host" class for exporting the VM as ova file; 2) After few minutes i see in the engine the command "START, DumpXmlsVDSCommand" that is completely istantly both on the host side ad the engine side, and it's fine: 2020-07-02 01:05:45,428+0200 INFO (jsonrpc/7) [api.host] START dumpxmls(vmList=[u'10e88cab-ec4f-4491-b51f-94e3d2e81a0a']) from=::ffff:$ENGINE_IP,39308 (api:48) 2020-07-02 01:05:45,428+0200 INFO (jsonrpc/7) [api.host] FINISH dumpxmls return={...
