10gig FC NIC shows in xenserver 7.2 but guest VM showing 1gig


I have plugged 10gig FC NIC card in a Dell R730 server & installed Xenserver 7.2.


Then, installed a guest VM of Windows Server 2016 with xentools & assign 10gig FC NIC card to this VM.


ethtool command shows 10gig speed on xenserver level but not showing 10gig in VM & also not getting 10gig speed in VM level.


Please help me.

If the card is on the HCL and you have any latest drivers applied, then you will likely have to go through Dell/Citrix as to what is wrong.

I guess there could be some misconfiguration somewhere like your traffic going over a management interface, or an upstream router

if those VM's are on different subnet/vlan's.
