Bridge problems - Host TCPDUMP unlike VM's TCPDUMP

Hello,

I have a problem where I'm running tcpdump on both my host machine and the virtual one(VM), and getting less packets in the VM. The VM is bridged on eth0 of the host.

Both VM and Host get their IP using DHCP.

The specific packets I'm not seeing inside the VM are requests for DHCP send by a PC trying to network boot with PXE.

So, in the HOST, TCPDUMP sees the BOOTP/DHCP packets; but in the VM, it doesn't.

I taught that a Bridged connection meant that both VM and HOST would see the exact same packets. Is that an error?

I'm not a network expert so my comprehension of TCP/IP is not very good. So, I've spend almost two days trying to fix this to no avail.

Thanks for any suggestions.
