[Bug 584048] Re: kvm images losing connectivity w/bridged network
@Serge Hallyn Sorry for big delay, just installed libvirt-fix-macaddr to our production system. No more network interrupts was observed on guest start/shutdown.

[Bug 584048] Re: kvm images losing connectivity w/bridged network
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 Server Team, which is subscribed to qemu-kvm in ubuntu. -- 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
[Bug 584048] Re: kvm images losing connectivity w/bridged network
Probably network freeze occur because of adding (on guest start-up) created tun/tap interface to the bridge. On guest shutdown tun/tap interface are removed from bridge. This add/remove operation to/from bridge of tap interface causes network freeze in my case. I have play around by replacing '-net tap' to '-net tap,ifname=tap.0,script=no,downscript=no' - no freeze occur. But in this case guest are not connected to the outside world. I have no idea does network freeze problem related to the virtual network kernel drivers or is it related to the physical network interface drivers of the host machine (in my case host if is 'RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)'). Also tested following, run ping: from LAN to IP of bridged if - time out during freeze from bridged machine to bridged if - no freeze from bridged machine to LAN - time out during freeze I have tested on: Lucid x64 + latest updates installed eucalyptus cloud kernel: 2.6.32-22-server qemu-kvm: 0.12.3+noroms-0ubuntu9 -- 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 Server Team, which is subscribed to qemu-kvm in ubuntu. -- 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

[Bug 388837] Re: Kernel panic when using Openswan 2.6.21 with KLIPS
Hello Jeremy, this issue have been occur on Pentium III 1GHz CPU (also on Pentium Celeron 633 Mhz) with Ubuntu 9.04/9.10 This is quite an old CPU, we are using such hardware as firewall. At this moment we are using 8.04 LTS. In several days I will prepare testing platform on latest kernel available.
