I had "dedicated" AWS instances that were rebooted. A dedicated instance means there is only one guest per box, right? So I'm curious why those had to be rebooted if there is no network-facing vector to this vulnerability. I guess because we could have read from the hypervisor's memory?


I believe that "dedicated" means that it's dedicated to your account. So, there can be more than one guest, but those guests are your EC2 instances.


Ah, thanks for the clarification! I guess that still means they were rebooting our machines in case the malicious actor was us. :-)
