To be honest we are a bit afraid to set 100% )), but we have tried to set 90% - no luck. I have also tested with 4.8 and 4.11 kernels - same results. I will try with Centos 6 and kernel 3.10 to check if something changes. VSwitch shows 1-2% load on the interfaces, and this host is not overloaded at all, so I don't think the VM has some lack of resources.
