[ovirt-users] Re: Dropped RX Packets

Hi Magnus, I've had a bad **virtual** network card three times in the last five years. Yes it' possible. I my case, NFS services didn't work as expected, but other services were ok. Today if this would happen again, i unplug and replug the VM nic. Like: GUI::Compute::VirtualMachines::VMname::Network Interfaces::nicN -> Edit CardStatus -> Unplugged :: OK -> Edit CardStatus -> Plugged :: OK HTH Oliver On 16.05.19 15:17, Magnus Isaksson wrote: > Hello all! > > I'm having quite some trouble with VMs that have a large amount of dropped packets on RX. > This, plus customers complain about short dropped connections, for example one customer has a SQL server and an other serevr connecting to it, and it is randomly dropping connections.
