Perhaps its related to your kernel version? With RHEL5 as the host OS I have not seen any problems with bonding and dhcp in either the host or the guest. The stack is: ------ ------ | tapX | ... | tapY | ------ ------ \ / --------- | br0 | --------- | ------- | bond0 | ------- / \ ------ ------ | eth0 | | eth1 | ------ ------ With the following bonding options: BONDING_OPTS="mode=active-backup primary=eth0 miimon=100" David Ahern On 11/05/2009 01:13 AM, Harald Dunkel wrote: > Avi Kivity wrote: >> >> So, it looks like a bridging problem.
