I am also observed network freeze. Used virtio drivers for network and for disk too (for WinXP/Win7 x86 guests), On every guest shutdown and sometimes on guest start-up network connection (to host and to guests) is interrupted from 2 seconds up to 10 seconds (sometimes more, it vary).
My case: Lucid x64 with eucalyptus installed on quad-core Intel CPU (motherboard 'Asus P6T SE'), network is bridged. Running kvm manually as well as using eucalyptus cloud - always same network freeze occur. -- kvm images losing connectivity w/bridged network https://bugs.launchpad.net/bugs/584048 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
