Increasing the Disk Space to 120GIB and RAM to 8GIB also involves the increment of swap space to 8GIB. The following steps were performed with CentOS 6.6 as VirtualBox host system and Oracle Linux 6.6 as guest system.
Increase Disk Space of Virtual Drive (e.g. resize Virtual Drive vm1disk1.vdi to 120GIB):
$ VBoxManage modifyhd vm1disk1.vdi --resize 122880
Increase RAM (e.g. resize Memory for VM vm1 to 8GIB):
$ VBoxManage modifyvm vm1 --memory 8192
Resize partition for lvm (e.g. adjust partition /dev/sda2 to new size).
Delete old partiton and create new, larger partition:
$ fdisk /dev/sda Command (m for help): d Partition number (1-4): 2 Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 2 First sector (155-2097151, default 155): Using default value 155 Last sector, +sectors or +size{K,M,G} (155-37786, default 37786): Using default value 37786 Command (m for help): w
Make enlarged partition available for LVM
$ lvm lvm> pvdisplay --- Physical volume --- PV Name /dev/sda2 VG Name vg_vm1 PV Size 19,51 GiB / not usable 3,00 MiB .. lvm> pvresize /dev/sda2 Physical volume "/dev/sda2" changed 1 physical volume(s) resized / 0 physical volume(s) not resized lvm> pvdisplay --- Physical volume --- PV Name /dev/sda2 VG Name vg_vm1 PV Size 119,51 GiB / not usable 716,00 KiB .. lvm> vgdisplay --- Volume group --- VG Name vg_vm1 System ID Format lvm2 .. VG Size 119,51 GiB ..
Increasing logical volume for swap by 6GIB (from 2 to 8GIB):
$ lvm lvm> lvdisplay .. --- Logical volume --- LV Path /dev/vg_vm1/lv_swap LV Name lv_swap VG Name vg_vm1 .. LV Size 2,00 GiB .. lvm> lvresize /dev/vg_vm1/lv_swap -L +6144M Size of logical volume vg_vm1/lv_swap changed from 2,00 GiB (512 extents) to 8,00 GiB (2048 extents). Logical volume lv_swap successfully resized
Increasing logical volume for root file system by adding the remaining space of partition:
$ lvm lvm> lvdisplay --- Logical volume --- LV Path /dev/vg_vm1/lv_root LV Name lv_root VG Name vg_vm1 .. LV Size 17,51 GiB .. lvm> lvresize /dev/vg_vm1/lv_root -l +100%FREE Size of logical volume vg_vm1/lv_root changed from 17,51 GiB (4482 extents) to 111,51 GiB (28546 extents). Logical volume lv_root successfully resized lvm> lvdisplay --- Logical volume --- LV Path /dev/vg_vm1/lv_root LV Name lv_root VG Name vg_vm1 .. LV Size 111,51 GiB .. --- Logical volume --- LV Path /dev/vg_vm1/lv_swap LV Name lv_swap VG Name vg_vm1 .. LV Size 8,00 GiB ..

End Swapping:
$ swapoff -v /dev/vg_vm1/lv_swap swapoff für /dev/vg_vm1/lv_swap
