Команда для визначення, чи працює Ubuntu у віртуальній машині?

Чи є команда чи інструмент, за допомогою яких можна визначити, чи працює Ubuntu в якості гостя в рамках програми віртуалізації, наприклад VirtualBox або Qemu, чи працює він на голому металі?

virt - що таке сценарій оболонки, який можна використовувати для виявлення, чи програма працює у віртуальній машині.

Програма виводить список "фактів" про віртуальну машину, отриманий з евристики. Один факт друкується на рядок.

Якщо нічого не надруковано і сценарій не виходить з кодом 0 (немає помилки), це може означати або те, що програма працює на голому металі або програма працює всередині типу віртуальної машини, про яку ми не знаємо або не можемо виявити.

    partitioning system.

    Status: confirmed by RWMJ using a Fedora guest running in z/VM

linux_vserver
    This is printed for backwards compatibility with older virt-what
    which could not distinguish between a Linux VServer container guest
    and host.

linux_vserver-guest
    This process is running in a Linux VServer container.

kvm This guest is running on the KVM hypervisor using hardware
    acceleration.

    Note that if the hypervisor is using software acceleration you
    should *not* see this, but should see the "qemu" fact instead.

    Status: confirmed by RWMJ.

lkvm
    This guest is running on the KVM hypervisor using hardware
    acceleration, and the userspace component of the hypervisor is lkvm
    (a.k.a kvmtool).

virt
    Some sort of virtualization appears to be present, but we are not
    sure what it is. In some very rare corner cases where we know that
    virtualization is hard to detect, we will try a timing attack to see
    if certain machine instructions are running much more slowly than
    they should be, which would indicate virtualization. In this case,
    the generic fact "virt" is printed.

Вибачте, але це ваш хлопець ....;)

Запустіть lspciі перевірте наявність рядка "VirtualBox".

Ви могли бігти lspci | grep VirtualBox

Ви також можете запустити lsusbта перевірити рядок "VirtualBox". Як отlsusb | grep VirtualBox

Також dmesgпрацює, працює dmesg | grep VirtualBoxабоdmesg | grep virtual

imvirt (не встановлений за замовчуванням, але доступний у всесвітньому сховищі)
