That's not what it says.
Amazon suggests moving to higher-performance instances to offset offset the performance hit from the fix.
HVM and m3 instances have higher performance for the same price, but they may also have been degraded by the fix.
- jamesjoethomas 9y agoI don't think that's right, Ctrl-F for "HVM" here: https://xenbits.xen.org/xsa/advisory-254.html https://xenbits.xen.org/xsa/advisory-254.html In the HVM case an attacker can't generate hypervisor addresses because the hypervisor runs in a separate address space, so HVM isn't vulnerable to the most easily exploitable of the disclosed issues.
