Hi Everyone ,
When live migrate vms between Xen-ng nodes i saw that couldn't push more then 1 Gbit traffic.
We have 3 nodes and all of them are connected 10Gbit to the switch (bond is configured but only on physical port up for now ) (bond is switch independent configured )
Then we back to Xen-ng hosts install iperf3 and made a test between nodes and get almost 8 Gbit traffic but do not care what happened to other 2 Gbit 😄 (maybe because no dpdk enabled default -->
[00:04 xcp-ng-zjiihqws ~]# ovs-vsctl get Open_vSwitch . iface_types
[geneve, gre, internal, ipsec_gre, lisp, patch, stt, system, tap, vxlan])
Using MTU 9000 on switch and Xen-ng side (actually 1500 mtu should be enough but we try to apple best practice) bonding 9000 and sub interface migration also same 9000 too.
Then tried 2-3 VM together to understand how did something in paralel and up to 1.24GB traffic we succeeded.
Actually i do not want push 10G or something just want to understand something wrong with me ? or really live migration traffic could not saturate my nic bandwith ? Should check some config to allow high traffic for migration ?
Thanks, Regards
VM
