Good morning!

I am having an issue on one VM that has a decent amount of network traffic. The network interface keeps dropping and coming back.

The guest is fedora 40 fully patched. This was originally fedora 41 but it had the same issues so I thought maybe the new version was having problems.

I have set the drive to virtio without adding threads.
I have upgraded to the newest kernel 6.11.
the host is up to date on nosub repo.

don't know if this is related or not but I do get stack traces from this machine sometimes too (also happened on fedora 41)

these network drops are happening all the time. The host they are on does not have them.

What other info can I give?

thanks!
