Hi Magnus,
do you notice any repetition there ? Does it happen completely random ?
Usually to debug network issues you will need tcpdump from Guest, Host and the
other side if possible.Is that an option ?
Do you see in the host's tab those RX errors ?
What is the output of "ip -s link" on the Guest ?

Hello all!
I'm having quite some trouble with VMs that have a large amount of dropped
packets on RX.
This, plus customers complain about short dropped connections, for example one
customer has a SQL server and an other serevr connecting to it, and it is
randomly dropping connections. Before they moved their VM:s to us they did not
have any of these issues.
Does anyone have an idea of what this can be due to? And how can i fix it? It
is starting to be a deal breaker for our customers on whether they will stay
with us or not.
I was thinking of reinstalling the nodes with oVirt Node, instead of the full
CentOS, would this perhaps fix the issue?
The enviroment is:
Huawei x6000 with 4 nodes
Each node having Intel X722 network card and connecting with 10G (fiber) to a
Juniper EX 4600. Storage via FC to a IBM FS900.
Each node is running a full CentOS 7.6 connecting to a Engine 4.2.8.2
Regards
Magnus
