Subject: [Sysadmins] kvm и нагрузка
Date: Tue, 02 Jul 2013 18:14:39 +0400
Message-ID: <51D2E04F.9050109@altlinux.ru> (raw)
Специалисты по kvm подскажите почему может быть такой эффект на хосте
LA=50 а на виртуалке 200.
Неужели kvm даёт оверхед по нагрузке в 4 раза?
на сервере всего 2 виртулаки. на 1 из них la=1 ибо не загружена, а на второй
Виртуалку загрузил с помощью stress
stress --cpu 64 --vm 32 --vm-bytes 20M --vm-stride 1 --vm-hang 30
--verbose --io 100 --hdd 100
P.S. гипертрединг не отключен. Но нежели он может такое давать?
