(please CC me on replies) I have been running kvm on this host for almost two years now. Using bridged networking, rather simple setup, with about 4 VMs and the hypervisor.
There is one bridge, br1 (there is an unused br0 which has no connection out) which is connected to the physical ethernet, one of the VMs is providing DHCP to the whole network. Things work fine, except, when I attempt to create a new host, or destroy a running host. I am playing with FAI profiles now, and so have "tested" this many times. Every time, the hypervisor briefly (5-10 seconds or so) stopps responding on the network, though, other systems which use the same bridge, have no issue. Script used to start the new VM: virt-install \ --connect qemu:///system \ --pxe \ -n test \ -r 512 \ --vcpus=1 \ --disk path=/dev/vg0/test \ --vnc \ --noautoconsole \ --os-type linux \ --os-variant debianLenny \ --accelerate \ --network=bridge:br1 \ --hvm I run this and get: Starting install... Creating domain... 0 B 00:00 Domain installation still in progress. You can reconnect to the console to complete the installation process. Timeout, server not responding. Then I am back on my local host (I ssh in to the hypervisor). I connect back in, and I can now use virt-viewer to see the console and watch the install (already in progress). The same thing happens when I "destroy" test via virsh (why graceful shutdown a system being blown away?) I have found that other systems (like the DHCP VM) still respond to ping during this time. In fact, one of them is providing the VPN end point which I am using to get to the hypervisor, and the VPN connection never drops. In the logs, at the same time, I see only the following, though, looking around indicates that these are common and probably not indicitive of an error: May 10 15:27:38 hyper kernel: [492763.100101] device vnet5 entered promiscuous mode May 10 15:27:38 hyper kernel: [492763.104224] br1: port 6(vnet5) entering listening state May 10 15:27:47 hyper kernel: [492772.133560] br1: port 6(vnet5) entering learning state May 10 15:27:56 hyper kernel: [492781.146314] br1: topology change detected, propagating May 10 15:27:56 hyper kernel: [492781.150297] br1: port 6(vnet5) entering forwarding state Bridge is setup in /etc/network/interfaces as follows: auto br1 iface br1 inet static address 192.168.0.6 network 192.168.0.0 netmask 255.255.255.0 gateway 192.168.0.1 bridge_ports eth100 bridge_hello 2 bridge_fd 9 bridge_stp on Anyone else run into this?
