We have a winner!
The classroom computers were mass-deployed using Clonezilla, from a disk image that already had the VM pre-configured. As a result, every VM had the same MAC address. Bridged networking put both hosts and both VMs in the same broadcast domain, which caused collisions in the ARP tables. I randomized the MAC address of one VM and everything suddenly started working.
It's never been an issue since we've never needed to use anything other than the default NAT adapter, so I've never even questioned it. I found the solution after plugging the computers directly into an access switch without success, and cross-checking
show mac address-tablewith the MAC reported by the VMs revealed that they were identical.
