Hello Eric, Supplemental packs (including driver disks) are used to modify and extend the functionality of the XenServer host, by installing software into the control domain (dom0) , this is different from host updates. Currently, Internet access is a necessity for XenServer 8 updates. Rfer : https://docs.xenserver.com/en-us/xenserver/8/update/apply-updates-using-xc To provide update notifications, XenCenter requires internet access. If your XenCenter is behind a firewall, ensure that it has access to the updates.ops.xenserver.com domain. To receive the updates, your XenServer hosts require internet access. If your hosts are behind a firewall, ensure that they have access to subdomains of ops.xenserver.com. However you should be able to use a proxy server and apply the updates. Refer : https://docs.xenserver.com/en-us/xenserver/8/update/apply-updates-using-xc#configure-updates-for-your-pool (Optional) Under Proxy Server, specify a proxy to use when synchronizing with the update channel. This proxy server is used for communication between the host and the public CDN.

Can you ensure that none of your VMs are actively using it ? Can you try to run the following on all the hosts in the pool and see if you are getting an output ? tap-ctl list | grep -i 8e18c874

@Steven Schoch Do you believe you can log this as a ticket at https://bugs.xenserver.com/ ?
