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!

Postfix / Dovecot / ClamAV / Spamassassin
2016-12-12 A whole buncha' links with contradictory information on how to properly set up a mail server ;-)
Disclaimer - My primary goal is to add proper Spamassassin (SA) filtering to an existing Postfix / Dovecot / roundcube installation, i.e.:
- use SA as a milter (mail filter) to attribute a spam score to incoming mail
- keep SA up-to-date
- train SA with spam/ham from the users' virtual mailboxes
- train SA according to user decisions (actual user or trained mail client with automatic/trained spam detection)
Here we go!
Most useful links; I stumbled upon them as soon as I knew what to look for:
