I'm trying to re-size the file system on a Centos 7 vm because I made the vm too small to even do a yum update. I already have done some configurations to the virtual machine and it would be pain to do it all over again, so I've been trying to re-size the virtual machine using virt-resizeOn the host machine when I run qemu-img info tkk.qcow2 I get the following information image: tkk.qcow2file format: qcow2virtual size: 17G (18253611008 bytes)disk size: 2.5Gcluster_size: 65536Format specific information:    compat: 1.1    lazy refcounts: trueThe virtual size used to be smaller but I used qemu-img resize tkk.qcow2 +10G Then I created a backup of the original file tkk.qcow2 with cp tkk.qcow2 tkk-orig.qcow2 and then I ran  virt-resize expand /dev/sda2 tkk-orig.qcow2 tkk.qcow2 to increase it's size. When I rerun qemu-img info tkk.qcow2 it shows that the Virtual Size has increase by whatever value I added on top of the previous value, but the Disk Size doesn't and I still can't do yum update due to too little space I would like to add at least 5GB more to this minimal vm.The output of virt-filesystems --long -h --all -a tkk.qcow2/dev/sda1                 filesystem xfs  -     -   15G  -/dev/centos_tkk/root filesystem xfs  -     -   1.3G -/dev/centos_tkk/swap filesystem swap -     -   204M -/dev/centos_tkk/root lv         -    -     -   1.3G /dev/centos_tkk/dev/centos_tkk/swap lv         -    -     -   204M /dev/centos_tkk/dev/centos_tkk      vg         -    -     -   1.5G /dev/sda2/dev/sda2                 pv         -    -     -   1.5G -/dev/sda1                 partition  -    -     83  15G  /dev/sda/dev/sda2                 partition  -    -     8e  1.5G /dev/sda/dev/sda                  device     -    -     -   17G  -I have been following these steps on this blog https://fatmin.com/2016/12/20/how-to-resize-a-qcow2-image-and-filesystem-with-virt-resize/
