migrate gentoo from virtualbox to vmware vsphere

migrate gentoo from virtualbox to vmware vsphere

prepare the disk with lvm(I like lvm):
(sda contain 18G)
fdisk /dev/sda
...(the /dev/sda1 500M, will mount to /boot
/dev/sda2 remain, will be the pv for lvm)

pvcreate /dev/sda2
vgcreate vg /dev/sda2
lvcreate -L15G -nslash vg
lvcreate -L1G -nswap vg

mount slash block device:
mount /dev/vg/slash /mnt/gentoo
mkdir /mnt/gentoo/boot
mount /dev/sda1 /mnt/gentoo/boot

translate whole system:
ssh root@gentoo.virutalbox
mount /boot
cd /
tar -cp bin/ boot/ etc/ home/ lib* media/ mnt/ opt/ root/ run/ sbin/ sys/ tmp/ user/ var/ | ssh root@genntoo.vmware 'tar xf - -C /mnt/gentoo'

chroot:
(AT gentoo.vmware)
mkdir /mnt/gentoo/proc
mkdir /mnt/gentoo/dev
mount -t proc /proc /mnt/gentoo/proc
mount --rbind /dev /mnt/gentoo/dev
cp -L /etc/resolv.conf /mnt/gentoo/etc/
chroot /mnt/gentoo /bin/bash
env-update && source /etc/profile
export PS1="(chroot) $PS1"

modify any system arguments:
vim /etc/conf.d/net
vim /etc/udev/rules.d/70-persistent-net.rules
vim /etc/fstab

install grub to mbr:
grub
grub>root (hd0,0)
grub>setup (hd0)

reboot and test OK!
