AESNI and guest hosts

AESNI and guest hosts

[Ryan Brown]

Host/KVM server is running linux 3.2.4 (Debian wheezy), and guest
kernel is running 3.2.5. The cpu is an E3-1230, but for some reason
its not able to supply the guest with aesni. Is there a config option
or is there something we're missing?

I don't think it's supported to pass that functionality to the guest.

[Ryan Brown]

Thanks for the reply, I was thinking AESNI was supported in the way
SSE/MMX and other cpu flags are supported? is a QEMU or a KVM issue?

Why not?  Perhaps a new libvirt or qemu is needed.

Should it be the case to add one of the following?

    <feature name='aes'/>
or..
    <feature name='aesni'/>

something like that?

Host is using linux kernel 3.2.4 (Debian Wheezy) libvirt (0.9.8-2),
qemu (1.0+dfsg-2), Guest is on linux kernel Ubuntu/3.2.5

The qemu name is aes.  Don't know about libvirt, suggest you start with
bare qemu first.
