Quoting ITec (1079...@bugs.launchpad.net): Thanks for the .xml. Nothing stands out there...
> What could you have done differently? The main thing is that I used raring, not quantal.

No, i did so from a single host. I used two laptops connected over an ethernet cable (with the one beign pxe+dhcp server for the other, my regular install setup). > - Are all hosts (KVM hypervisor, and both remote hosts) connected to the same physical network switch by 1Gbit/s? No switch involved. I'll try using just quantal first on the VM host, but wouldn't that be interesting if adding a switch caused this! -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/1079212 Title: network slow when 2 VMs using virtio net bridged to same pyhs. network device on kvm host To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1079212/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
