I start my virtual machine as follows: qemu-kvm -hda /dev/kvm_sdb/geust_root -m 1024 -net tap -net nic,vlan=0,macaddr=00:16:3e:00:00:02 -daemonize -nographic -smp 2 The problem is that when the guest (also CentOS 5.1 x86_64) utilizes the network heavily (scp to a machine on the same switch, around 12 mbyte/s) the network on the virtual machine just drops out. I can no longer ping the virtual machine, and any existing SSH sessions die. If I connect to the virtual machine using VNC everything looks okay (eth0 is up, routes are okay), but I still cannot connect to anything. All other virtual machines on the same host continue to work as if nothing has happened. The same problem occurred in -58 and -59. /var/log/messages on the guest says: NETDEV WATCHDOG: eth0: transmit timed out eth0: link up, 100Mbps, full-duplex, lpa 0x05E1 Any suggestions (permanent fixes or temporary workarounds, I'll take what you got) would be much appreciated. Thanks for all the great work :) -Arne ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
