Hey all, I'm using KVM to setup a virtual machine. Using this machine i'm attempting to setup a connection to host machine using the tap interface. I setup the interface using the standard tap method and then start the KVM using the following:
kvm -net nic,model=e1000 -net tap,ifname=qtap0,script/etc/kvm/kvm-ifup -drive file=./image.img When the virual machine starts i setup the IP addresses (host = 192.168.100.1 vm = 192.168.100.2) and I am able to bring between the host and virtual machine. However, what i need to do is to be able to send jumbo frames between the two. I therefore increase the MTU size on both the host machine and virutal machine to 9000. Now when i try to do from within the host ping -s 4096 192.168.100.1 I go no respone. So i started with a lower packet size and figured out below a size of 4054 packets were sent and recevied (without ip fragmentation), however, as soon as the packets were >= 4055 it stopped working. Is this a known problem? Have I set something up incorrectly? Thanks for your help P.S.
