found the solution on proxmox forum.
just disable jumbo frames on centos host interface ifcfg and ethernet switch.
hope this help someone.
$ ifconfig virbr0 virbr0 Link encap:Ethernet HWaddr 52:54:00:EB:2D:7B inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
My MTU=1500, so no jumbo frames. Rats!
Thank you for the suggestion!
