Purpose
To build a simple VM lab in Ubnuntu. Nothing fancy.
Hardware
My primary personal computer, a Lenovo X220 laptop with
- 3rd gen i5
- 8GB RAM
- 256GB Crucial BX200 low end SSD
- 500GB HGST Travelstar Z7K500
Software
- OS is obviously Ubuntu. At the time of writing I am using Bionic Beaver.
- ZFS Filesystem tweaked to use 2GB of ARC
- Red Hat libvirt
Process
Install Packages
sudo apt install virt-manager sudo systemctl start libvirtd sudo systemctl enable libvirtd sudo apt install libzfs2linux sudo apt install zfs-dkms
Prepare Storage
Partition disk
(Not really needed, but I got into the habbit)
sudo fdisk /dev/sdb
Command (m for help): p
Disk /dev/sdb: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x970f8931
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p):
Using default response p.
Partition number (1-4, default 1):
First sector (2048-976773167, default 2048):
Last sector, +sectors or +size{K,M,G,T,P} (2048-976773167, default 976773167):
Created a new partition 1 of type 'Linux' and of size 465.8 GiB.
Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
Encrypt Disk
This is really just to make disposing of the drive easier. If the drive dies I can throw it away without worrying about physically destroying it.
sudo cryptsetup luksFormat --type luks2 /dev/sdb1 WARNING! ======== This will overwrite data on /dev/sdb1 irrevocably. Are you sure? (Type uppercase yes): YES Enter passphrase for /dev/sdb1: Verify passphrase:
