Sorry if I have missed anything, but I have been trying hard to understand

far failed.
Please can you share your suggestions as to where to look after in qemu

Ok, so theoretically it should work.
That's useful suggestions. Let me debug virtio-net driver for possible

(ifconfig eth0 RX counter is unchanged. tcpdump also doesn't detect any
packets.) . I don't want to use any NetClient APIs and want to directly
inject packets into the guest vring.
Please can you share if my approach and understanding is correct.

But during unplugging , we can't see the event echo 0 > cpu8/online.
Just for additional check, in my code I have added following udev rule
echo 0 > cpu[0-9]*/online. May be this is of any help.

Does the only solution is to shutdown the VM, upgrade qemu and then
start with new QEMU and new PC model .

Hi Andreas,
"the point is that the machine version on the destination side needs
to match the source side". I hope this is just to avoid the licensing
issue. Else, in all other circumstance, we can specify different pc
models while migrating from source to destination.
Anshul Makkar
O
from pc model 1.0 in qemu 1.0 to pc model 2.0 (pc-i440fx-2.1) to qemu
2.0.
Yeah, true, if we have to avoid the licensing issue then we have to
use same PC model.

Or iommu->translate leads to hardware MMU call.
We are developing a high speed packet transfer mechanism using
infiniband cards. So, trying to analyse every possible bottleneck.
Confused here, please suggest.

Hi,
Just want to check this small piece of implementation detail in qemu.
Is it possible to change the mac address of VM at runtime and does
the same information is conveyed to host if we are using Virtio based
transfers (approach).
