Доброго времени суток!
Есть две (двух головые ) машинки с Intel Xeon 2.4 и
kernel-image-ovz-smp-2.6.18-alt8. Помогите разобраться почему в /proc/cpuinfo
видно только 2 CPU. правда опция ht имеет место присутствовать. Темболее
что ранее стоявшая FC4 с openvz ядром показывала 4 просессора. Тоже ядро
(kernel-image-ovz-smp-2.6.18-alt8) установленое на ПК (P4 ГГц) прекрасно дает
понять о наличии hyperthreading показывая в /proc/cpuinfo 2 проца.
PS:
#grep ^append /etc/lilo.conf
append="nolapic pci=noacpi acpismp=force"
]# dmesg | grep CPU
