Thread: qemu networking - is there a howto?

    Exclamation qemu networking - is there a howto?

    hi,

    i have installed ubuntu hardy and qemu and kqemu. i have created a couple of VM and i am now looking to find out how network these machines.
    i used qemulator to create my VMs, and i do understand how TAP connectors work.
    i suppose in future GUI applications for qemu will provide a more user-friendly interface for working with their networking but for the moment it is necessary to do it manually.

    many thanks for all assistance.

    regards,


    Nicolas

    Thanks,

    i have followed the information on that page but it now causes troubles when i suspend my laptop.
    i believe the problem is to do with the bridge interface that i created on the /etc/network/interfaces.

    would there be anything that i can do to setup the networking for VMs on a laptop?


    Many thanks,

    Yeah, I just remembered, running kvm module causes suspend problem.
    https://bugs.launchpad.net/ubuntu/+s...22/+bug/113038

    Workaround:
    Instead of adding kvm into /etc/modules (so it's permanently loaded), use modprobe to load and unload the module as needed.

    EDIT:
    Networking part is complicated thing, but it's possible. The howto gives a comprehensive instructions, but you will need to read carefully and thoroughly understand the options.
