Could not map all requested links to physical resources.

[Ziming Mao]

Hi, I restarted my experiments on Utah today.

https://www.cloudlab.us/status.php?uuid=1b846ea5-e6bb-11ec-b318-e4434b2381fc

I requested 8 xl170 nodes (Profile: https://www.cloudlab.us/p/7f59dda49f28e5b2cfba6bc545eae2e5e6b5bd22) and I checked that there are 31 xl170 nodes available. 

However, I got the following error. 

Error:

Hi. You are asking for 25G network links, but the the xl170 nodes
do not have 25G interfaces, only 10G. You will need to change your
profile or choose a different node type. See this page for a list
of all node types in Cloudlab: https://www.cloudlab.us/portal-hardware.php

Also, since the xl170s have only a single experimental link, and you
want to use a remote blockstore, you need these on all your links.
Your profile was recently changed and removed them:

fslink1.best_effort = True
fslink1.vlan_tagging = True
fslink1.link_multiplexing = True
