Re: [Devil-Linux-discuss] 1.8 testing release uploaded

usually qemu/kvm identify itself as:

> CPU: AMD QEMU Virtual CPU

and virtualization detection will definitely work. However, for "-cpu
host" option it uses real cpu information, so I'm afraid detections will
not work.

i.e

# qemu-system-x86_64 --version
QEMU emulator version 2.5.0, Copyright (c) 2003-2008 Fabrice Bellard

no "-cpu host":

> qemu-system-x86_64 -enable-kvm -kernel /tmp/vmlinuz -initrd
/tmp/initrd -append "console=ttyS0" -serial telnet::9001,server,nowait


# mount -t proc none /proc
# cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 6
model           : 6
model name      : QEMU Virtual CPU version 2.5+


with "-cpu host":

# qemu-system-x86_64 -enable-kvm  -cpu host -kernel  /tmp/vmlinuz
-initrd /tmp/initrd -append "console=ttyS0" -serial
telnet::9001,server,nowait

# mount -t proc none /proc
# cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 16
model           : 10
model name      : AMD Phenom(tm) II X6 1090T Processor

i'll try to find another identification sign - and let you know. My
assumption is - qemu uses a very specific seabios, so "dmidecode" or
something similar should identify a vm pretty good.
