Here are the steps I used to migrate a CentOS 7 VM from (presumably?) an ESXi server, to a local VirtualBox environment.
The LVM volumes were not detected at boot, and after the boot timeout, the OS fell back to the Dracut emergency shell.
- get a CentOS minimal installation CD
- check the VM's resources and peripherals:
- ensure there are no floppy drives (!)
- setup CPU and RAM resources
- check virtual drives
- add an SCSI optical drive if needed
- optional: convert the virtual drive images from VMDK to VDI
- mount the CentOS installation disc
- boot on the installation disc:
- select "Troubleshooting", then "Rescue"
- let the rescue utility detect filesystems and mountpoints
$ chrootto the detected environment- backup files:
/etc/fstab/boot/grub/grub.cfg
- under /boot, backup the initrd and initramfs for the current configuration (these will be overwritten)
- compare the current
/etc/fstabwith the output of$ lsblkand$ blkid - if needed, manually edit /etc/fstab to use the appropriate block device UUIDs, identifiers and mountpoints
- regenerate GRUB configuration:
$ grub2-mkconfig -o /boot/grub2/grub.cfg
- if needed, reinstall GRUB:
$ grub-install /dev/sda
- rebuild initrd:
$ mkinitrd --force /boot/<initrd_image> <kernel_version>
- rebuild initramfs:
$ dracut --force <kernel_version>
- exit the chroot
- unmount the installation disc
- reboot
- optional but highly recommended: cross your fingers
- ...
- profit!

Pro: no need to setup a DNS server to test virtualhosts Con: keep in mind that all "fake" hosts will point to 127.0.0.1!
- Use /etc/hosts to declare test hosts / domains / subdomains
#<ip-address> <hostname.domain.org> <hostname> 127.0.0.1 localhost.localdomain localhost 127.0.0.1 host.localdomain host 127.0.0.1 sub.host.localdomain sub.host ::1 localhost.localdomain localhost- Allow per-user virtualhost definition in either (depending on your distro)
/etc/httpd/conf/httpd.conf/etc/apache2/apache2.conf
Include
/home/albert/.httpd/*.conf- Profit! Create virtualhosts with local hostnames :)
