Package: qemu Version: 0.11.1-2 Severity: normal
I have a collection of about 14 virtual machines running a variety of Linux 2.4, 2.6 and OpenBSD based guests, all connected using some VDE virtual ethernet switches. All the machines use e1000 NICs. A recent upgrade to this version of qemu has had a determental effect on these NICs; from time to time, perhaps once or twice a day, a machine will suddenly decide its NIC is broken and stop talking IP over it: Linux 2.4: Mar 12 16:16:54 viggen kernel: NETDEV WATCHDOG: bond0: transmit timed out Mar 12 16:16:54 viggen kernel: e1000: bond0 NIC Link is Up 1000 Mbps Full Duplex Mar 12 16:17:04 viggen kernel: NETDEV WATCHDOG: bond0: transmit timed out Mar 12 16:17:04 viggen kernel: e1000: bond0 NIC Link is Up 1000 Mbps Full Duplex (ignore the fact this NIC is called bond0; it really is an e1000 I just renamed it for compatibility with some virtualised software). Linux 2.6: Mar 10 02:28:26 freehand kernel: ------------[ cut here ]------------ Mar 10 02:28:26 freehand kernel: WARNING: at net/sched/sch_generic.c:219 dev_watchdog+0x1bf/0x1d0() Mar 10 02:28:26 freehand kernel: NETDEV WATCHDOG: bond0 (e1000): transmit timed out So far I haven't observed the OpenBSD boxes doing this, though that may be because they transmit and receive far less traffic than my Linux boxes; it may be traffic related. I haven't changed the guest OSes at all since a previous version of qemu where this wasn't happening, so I'm fairly convinced it's an issue with qemu rather than the guests. -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (990, 'testing'), (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-trunk-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages qemu depends on: ii qemu-system 0.11.1-2 QEMU full system emulation binarie ii qemu-user 0.11.1-2 QEMU user mode emulation binaries ii qemu-utils 0.11.1-2 QEMU utilities qemu recommends no packages.
