Hi Keir,
I find that you are the author of the netback driver of
linux-2.6.18-xen Dom0 and I hope I can get some help from you. I want to
quickly have a knowledge about how a data packet is transferred between two
VMs on the same Xen hypervisor if the TCP/IP protocol is used. I am not
sure whether a data packet from DomU1 to DomU2 is transferred like this:
DomU1(front-end network driver)-->Dom0(back-end network driver of
DomU1)-->Dom0(Virtual bridge)-->Dom0(back-end network driver of
DomU2)-->DomU2(front-end network driver)
Is the virtual bridge in Dom0 in charge of forwarding the data packet to
other Domains? Does the data packet transfer between two VMs in the same
way (the transfer path mentioned above) in both the vif-bridge mode and
vif-nat mode?
Any reply is appreciated.
Best Regards,
Bei Guan
