I'm running Qemu based VMs on top of debian,
In my enviornment the data center gave us two vlans on one NIC,
As I build VMs' NIC on top of a bridge which is build on top of vlans, when vlans become two the network connectivity of VMs is lost, but with one vlan it's OK.
Any help on this issue?
it's my interfaces configuration file,
#network interface settings
auto lo
iface lo inet loopback
iface eth0 inet manual
address 0.0.0.0
netmask 0.0.0.0
auto eth0.972
iface eth0.972 inet static
