[sheepdog-users] Many vdi snapshots may block the network

Hi, I was doing a stress test on my testing cluster: a cylcle that creates
a snapshot for each one of my vdi and then remove them.

While the script was running may colleagues complained about frozen
Internet connection.
As soon as the script stopped, they also stopped complaining.

I tried again to run the script, and the connection went off.

Does the action of taking snapshot generate lots of broadcast?
May this be related to corosync more than sheepdog?

Note: my 4 nodes are using dedicated nic and switch for syncing.
