When I unplug the ethernet cable from the physical host, guest fails to
reconnect; host does reconnect.
A very simple configuration here, with an almost default Debian 7 on
both host and guest:
-- ON HOST:
/etc/network/interfaces
auto lo
iface lo inet loopback
auto br0
iface br0 inet dhcp
bridge_ports eth1
bridge_stp off
bridge_maxwait 0
bridge_fd 0
-- ON GUEST:
/etc/network/interfaces
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.168.1.109
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1
dns-nameservers 192.168.1.1
QEMU is started as:
/usr/local/bin/qemu-system-x86_64 -hda /media/raid1/qemu-109 -m 8G -smp
4 -enable-kvm -netdev bridge,id=br109 -device
virtio-net-pci,netdev=br109,id=nic0,mac=00:00:00:00:01:09 -k it -daemonize
QEMU emulator version 2.3.0
Nothing appears on dmesg. Any hints?
