We have two hosts with 82599 NIC, OS is Xenserver 6.2 SP1,
VM 1 is on host 1, OS is CentOS6.4 64-bit, as the dhcp server
VM 2 is on host 2, OS is CentOS6.4 64-bit, as the dhcp client
VM 2 has a VF configured dhcp, and can get an IP address at the first time,
But after 'service network restart' it can't get an IP address any more
When VM 2 can get an IP address at the first time
tcpdump result on VM2,VM1,host1,host2 are the same
When it can't get an IP
we can still see both dhcp request and dhcp reply package on VM1 and host1
But only dhcp request package on VM2 and host2
Can anyone give a clue
Thanks in advance
