    Anyone confirm whether or not Intel Xeon E5-26xx v3 KVM can pass AES-NI aes cpu flag to guests ?

    Have a bit of a dilemma as I just migrated my Fremont Linode 4GB server from Xen to KVM and from E5-2680v2 to E5-2680v3. But the aes cpu flag is missing and AES-NI is 1/2 the performance on the E5-2680v3. However, I had a Linode Singapore E5-2680v3 KVM and it had AES-NI performance that is twice...

    TLS 1.2: AES_128_GCM or AES_256_CBC for better security?

    Hi, I want to set up a ssl server with best security. I can force my friends to use browsers with TLS support. For now, Chrome support AES_128_GCM and AES_256_CBC with TLS 1.2. What cipher should I choose? Are there any diffrence on 128 bits and 256 bits in this case?
