Resize VM disk with KVM

Today i will install Code Ready. You can install Openshift on your laptop. See this link . My RHEL 8.4 VM has a small disk and first i need to resize the disk and then install CodeReady

Using this commands i change from 20 GB to 50GB disk

First you need to locate the vm disk with the command

sudo virsh domblklist rhel8-1

the output was:

Target Source
——————————————————-
vda /var/lib/libvirt/images/rhel8-2-clone.qcow2
sda –

To resize the disk the VM must be not running and must not have a snapshot.

Just type this command and add 30GB

sudo qemu-img resize /var/lib/libvirt/images/rhel8-2-clone.qcow2 +30G

Start the vm and verify the disk using lsblk command

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sr0 11:0 1 1024M 0 rom
vda 252:0 0 50G 0 disk
|-vda1 252:1 0 1G 0 part /boot
`-vda2 252:2 0 29G 0 part
|-rhel-root 253:0 0 26G 0 lvm /
 `-rhel-swap 253:1 0 3G 0 lvm [SWAP]

One Monitor Two Macbooks

 

I have on my desk now 2 MacBooks Pro a monitor, a keyboard and a magic mouse. For the two computers to share the monitor, keyboard and mouse I should buy a KVM but I don’t want to have too many cables on the desk and also the cost of the KVM for the macbooks is too expensive for me in Brazil.

I found an interesting solution which was to connect each macbook using HDMI adapters to the monitor and use a software to switch the keyboard and mouse between the computers.

I’m testing Barrier and so far everything is working fine.

There is feature very cool :  You can copy and paste from one computer to another.

You can see this video and see how it works
