[pve-devel] kernel 3.10 , packet loss and latencies problem

Ok,I have rollback to 2.6.32. 

I think they are a bug with 3.10 and my opteron hosts. (don't have noticed theses problem with my intel test cluster)

I'll wait for the final rhel7 kernel release.

some news: 

seem that vms are freezing for some ms. (tested with vnc console to be sure). 

stop/start seem to help, but I need to wait a little more.

Hi, 

I have put in production my first host with kernel 3.10, 

I have a lot of packets loss and latencies from the guest. 

host response fine. 

I have tested with a broadcom bnx2 and intel nic, same problem. 
guest windows or linux (kernel 3.7 or 3.10) 

I had tried to disable offloading with ethtool , doesn't help. 


Has somebody else have this problem ? 


Vms was live migrated, so maybe it come from that. I'll stop/start them to see if it's helping. 

Alexandre
