Qunfang, I searched the Internet and found out that older CPUs that do not support the NX/XD bit, cannot run Win8 (also on bare metal). I suggest that you try a different CPU type, and if it works, close the bug. Thanks, Ronen. Hi, Ademar and Ronen Thanks for the reply. From the comment 0, we could see there's no 'nx' flag in the cpu info, but we re-check the system again just now, the 'nx' flag exists! So we will re-test again to see whether the problem is still reproducible. And btw, we tested on some other system, could not reproduce the issue. Thanks, Qunfang Retest with the same machine: processor : 159 vendor_id : GenuineIntel cpu family : 6 model : 47 model name : Intel(R) Xeon(R) CPU E7- 2860 @ 2.27GHz stepping : 2 microcode : 0x36 cpu MHz : 2261.007 cache size : 24576 KB physical id : 7 siblings : 20 core id : 9 cpu cores : 10 apicid : 243 initial apicid : 243 fpu : yes fpu_exception : yes cpuid level : 11 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm pcid dca sse4_1 sse4_2 popcnt aes lahf_lm ida arat epb dtherm tpr_shadow vnmi flexpriority ept vpid bogomips : 4521.89 clflush size : 64 cache_alignment : 64 address sizes : 44 bits physical, 48 bits virtual power management: Steps as comment 0 There is nx flag this time, maybe last time(comment 0) disable nx flag. this time can boot win8 guest successful,so I will close this bug, If I am wrong, please let me know it. Best Regards! Gleb, Junyi asks about emulating the NX flag on CPUs that do not support it. Maybe you can answer. (In reply to Ronen Hod from comment #9) > Gleb, > Junyi asks about emulating the NX flag on CPUs that do not support it. Maybe > you can answer. The answer is "no". Hi Gleb and Ronen, Really thanks for your confirmation. Best Regards, Junyi |
