Which versions of the drivers (ixgbe, ixgbevf) are you using? >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 It seems the second VF is not receiving the packets after a reset. Does this happen only for dhcp or in general (static IP)? Also if the interface is not receiving packets it could be that they are being dropped for some reason - in certain cases there may be messages by the PF driver (like spoofed packets) - you may want to check dmesg on the host side.
