Hyper-V performance with Microsoft EMET EAF Feature in VDI and ReCoBS
emet useful remote-controlled browsers systems (recobs) , virtual desktop infrastructure (vdi). applications protected emet eaf feature run 10 times slower (or @ 10% speed) in hyper-v guests presumably because processor debug registers used. performance counter "hypervisor root virtual processor(*)\debug register accesses/sec" increases few 10 thousands on system when emet eaf protected applications run. any ideas improve performance without loosing eaf benefits? the emet documentation doesn't explicitly reference hyper-v, but: “some virtual machines not support debug registers (and consequently eaf). however, eaf option still available configuration if emet being run on machine doesn’t support debug registers. setting option on machines have no effect. be aware of limitation when configuring eaf.“ drm , copy protection (securom and/or safedisc afair) software affected. references: aslr bypass mitigated eaf: https://badishi.com/tweaking-metasploit-mod...
