Ok, so maybe it's packet loss or something like that.

can you post your /etc/network/interfaces of theses 10gb/s nodes ?

Yes, Multicast works (tested with omping)

when you loose the quorum, is multicast working or not ? 

(test with omping for example)

Hi Alexandre 

Many thanks for your reply, and here my answer and comments: 

>is multicast working ? 
Yes 

Here a better explanation: 

- I have 8 nodes in a PVE cluster. 
- 5 Nodes have PVE 3.3 version with the Kernel 3.10.0-19 version 
- 3 Nodes have PVE 2.3 version with the Kernel 2.6.32-19 version 
- Of the 5 nodes with PVE 3.3 version, 2 of them has NICs of 10 Gb/s 
- I have only a VM in HA running in a PVE node that have the NIC of 10 Gb/s, 
the other node with the NIC of 10 Gb/s is his pair of HA and not has VMs 
running 
- In other pair of nodes (with NICs of 1 Gb/s and kernel 3.10.0-19 version) 
also has VMs in HA, but never i had problems with these nodes. 

So in my PVE cluster of eight nodes, the problem of quorum begins when the 
VM that is on the node that have the NIC of 10 Gb/s has activity, and only 
after some hours, and this disagreeable happening of loss of quorum occur 
simultaneously in my two nodes that has the NICs of 10 Gb/s.

off 

Hi to all. 

I have a serious problem with the loss of quorum in two nodes that has Intel 
NICs of 10 gb/s. 
Also the VM of this node is turned off 
I don't know if it is a bug or i missed of something. 

Please see this link, and if you can help me, please do it:
