Hi, I'm running qemu-kvm-0.12.1.2. I know it is an old version, but I hope people can still help me with this.
I run a VIF for my virtual machine with the following settings in the qemu command: -netdev tap,ifname=vif-0-3, ,id=hostnet0 -device e1000,netdev=hostnet0,id=net0,mac=52:54:99:ff:15:14,bus=pci.0,addr=0x3 In parallel I do the same with using virtio-net instead of e1000 and it doesn't make a difference to my problem. The problem is the following: For a few hours my VM runs just fine and networking and everything else works. Then suddenly the VIF seems to hang. I transmit packets from inside the VM, and on the VM's networking interface (eth0) I can see the packet TX counter increasing. However, on the host side where vif-0-3 resides, I don't see the packet RX counter increasing at all anymore. Now I wonder, where do my packets get lost, when they definitely are transmitted on the guest interface, but don't show up at all on the host VIF? This only ever happens in this direction (packets transmitted from the guest), but never the other way round (packets are still being received on the guest). Has anyone ever seen this? Is this a known bug of my QEMU version? Thanks for your help. Anna
