  • 怎样推断server为虚拟机还是物理真机?

     dmidecode |grep -A20 "Memory Device$"|sed -n -e'/Locator/p' -e '/Size/p'|grep -v "Bank Locator"
    看内存分布
    [真机]# dmidecode |grep -A20 "Memory Device$"|sed -n -e'/Locator/p' -e '/Size/p'|grep -v "Bank Locator"
            Size: 4096 MB
            Locator: DIMM0
            Size: 4096 MB
            Locator: DIMM1
            Size: 4096 MB
            Locator: DIMM2
            Size: 4096 MB
            Locator: DIMM3


    [虚拟机]#  dmidecode |grep -A20 "Memory Device$"|sed -n -e'/Locator/p' -e '/Size/p'|grep -v "Bank Locator"
            Size: 1024 MB
            Locator: RAM slot #0
            Size: 512 MB
            Locator: RAM slot #1
            Size: 256 MB
            Locator: RAM slot #2
            Size: 128 MB
            Locator: RAM slot #3
            Size: 64 MB
            Locator: RAM slot #4
            Size: 16 MB
            Locator: RAM slot #5
            Size: No Module Installed
            Locator: RAM slot #6
            Size: No Module Installed
            Locator: RAM slot #7
            Size: No Module Installed
            Locator: RAM slot #8
            Size: No Module Installed
            Locator: RAM slot #9
            Size: No Module Installed
            Locator: RAM slot #10
            Size: No Module Installed
            Locator: RAM slot #11
            Size: No Module Installed
            Locator: RAM slot #12
            Size: No Module Installed
            Locator: RAM slot #13
            Size: No Module Installed
            Locator: RAM slot #14

    -------》内存分布不均匀




    ---直接看产品名
     dmidecode |grep "Product"


    [root@lixora ~]#  dmidecode |grep "Product"
            Product Name: VMware Virtual Platform
            Product Name: 440BX Desktop Reference Platform


    [root@oracle sysbench-0.4.12]#  dmidecode |grep "Product"
            Product Name: System Product Name
            Product Name: P8Z68-V LX


    ------观察硬件设备。假设看到VMware 类似字符基本为虚拟机了

    [虚拟机】lspci -b|grep VMware
    00:07.7 System peripheral: VMware Virtual Machine Communication Interface (rev 10)
    00:0f.0 VGA compatible controller: VMware SVGA II Adapter
    00:11.0 PCI bridge: VMware PCI bridge (rev 02)
    00:15.0 PCI bridge: VMware PCI Express Root Port (rev 01)
    00:15.1 PCI bridge: VMware PCI Express Root Port (rev 01)
    00:15.2 PCI bridge: VMware PCI Express Root Port (rev 01)
    00:15.3 PCI bridge: VMware PCI Express Root Port (rev 01)

    00:15.4 PCI bridge: VMware PCI Express Root Port (rev 01)
