I am in the process of virtualizing (KVM) my server at school (I'm a math teacher). I have a guest Ubuntu 11.04 server running fine. The network performance of the guest is great. But, I am having trouble with the host (Ubuntu 11.04) network performance. It is very slow. Sometimes I can ping the host from the guest and sometimes I cannot. Also, I have "destroyed" and "undefined" the virbr0, as I am using the bridge and not NAT.
I will be administering this server remotely and need independent ssh access to both the host and the vm.
Host network interface:
iface eth0 inet manual
iface br0 inet static
Guest network interface:
iface eth0 inet static
I've spent a week trying to find an answer, but to no avail. Could one of you kindly point me in the right direction? If more info is needed, please let me know what you need to see.
Thanks for any help you can give.
