Hi all,
For my academic project to analyse the Performance of transport protocols in
Live Migration of Virtual Machines.I have configured the live migration
using tcp and I succeed the live migration.
Now for my further remaining project work I need to do the same thing for
the UDP implemataiton.When I changed the command in virsh, (My fianl command
in TCP is virsh migrate --live ubuntu21 qemu+ssh:// to udp it is not workng. It is given that qemu embeds user
mode network stack which includes tcp,dhcp,udp.etc within the wemu process.
Its giving the error no API found for UDP.
---Now i want to implement the patch file for migration using UDP if

---Where I should change the API in order to perform the live migration
using UDP.

---Is any patch file available so that modifying that patch file will
perform the Live Migration using UDP.

---If implementation using not possible with UDP please give me the details
why that can not be implemented and is any proofs for that reasons are

--Is there any other transport layer protocols can be used instead of TCP
during Live migration.?

--How about using RUDP instead of TCP.

Thanking You in advance.

Thanks and Regards
