VMware VM
[root@zetawiki ~]# ethtool -i eth0 | grep driver
driver: e1000

5 방법 5: fdisk[편집]

Xen VM
[root@zetawiki ~]# fdisk -l

Disk /dev/xvda: 31.4 GB, 31457280000 bytes
255 heads, 63 sectors/track, 3824 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

    Device Boot      Start         End      Blocks   Id  System
/dev/xvda1   *           1          13      104391   83  Linux
/dev/xvda2              14        3824    30611857+  8e  Linux LVM
KVM
[root@zetawiki ~]# fdisk -l

Disk /dev/vda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *           1          13      104391   83  Linux
/dev/vda2              14        5221    41833260   8e  Linux LVM
VMware VM
[root@zetawiki ~]# fdisk -l

Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          38      305203+  83  Linux
/dev/sda2              39        2353    18595237+  83  Linux
/dev/sda3            2354        2610     2064352+  82  Linux swap / Solaris
→ VM이지만 sda로 나오므로 확인 어려움
