According to /usr/share/libvirt/cpu_map.xml <model name='Westmere'> <model name='Nehalem'/> <feature name='aes'/> </model> as well as http://ark.intel.com/products/47925/Intel-Xeon-Processor-E5620-%2812M-Cache-2_40-GHz-5_86-GTs-Intel-QPI%29 Westmere should support the aes instruction. The fact that aes is not reported in /proc/cpuinfo, suggests a bug in the kernel or in the cpu itself. What is your kernel version? Could you attach the output of your dmesg? Created attachment 926415 [details]
dmesg
Kernel: 3.10.0-123.6.3.el7.x86_64
from dmesg:
[ 0.084946] smpboot: CPU0: Intel(R) Xeon(R) CPU E5620 @ 2.40GHz (fam: 06, model: 2c, stepping: 02)
[ 0.186672] Performance Events: PEBS fmt1+, 16-deep LBR, Westmere events, Intel PMU driver.
It is configured as module (AES_NI_INTEL): cat /boot/config-3.10.0-123.6.3.el7.x86_64 |grep AES CONFIG_SND_MAESTRO3=m CONFIG_SND_MAESTRO3_INPUT=y CONFIG_CRYPTO_AES=y CONFIG_CRYPTO_AES_X86_64=y CONFIG_CRYPTO_AES_NI_INTEL=m CONFIG_CRYPTO_CAMELLIA_AESNI_AVX_X86_64=m CONFIG_CRYPTO_CAMELLIA_AESNI_AVX2_X86_64=m CONFIG_CRYPTO_DEV_PADLOCK_AES=m But it won't load through modprobe: modprobe -v aes insmod /lib/modules/3.10.0-123.6.3.el7.x86_64/kernel/arch/x86/crypto/aesni-intel.ko modprobe: ERROR: could not insert 'aesni_intel': No such device It could be a BIOS problem or a kernel issue. I'll check for an updated BIOS version Maybe somebody from kernel can explain that. I finished updating the BIOS from 2.1b to 2.1c and it works properly no Sorry, not a bug. But I'm not allowed to close it anymore I'm happy to be at your service. Thanks for your report. |
