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,如果看到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)
