This is my starting point. I am using your instructions as posted
here: http://libguestfs.org/virt-resize.1.html
# virt-filesystems --long -h --all -a img-1.qcow2
Name Type VFS Label MBR Size Parent
/dev/sda1 filesystem xfs - - 500M -
/dev/centos/root filesystem xfs - - 15G -
/dev/centos/swap filesystem swap - - 820M -
/dev/centos/root lv - - - 15G /dev/centos
/dev/centos/swap lv - - - 820M /dev/centos
/dev/centos vg - - - 16G /dev/sda2
/dev/sda2 pv - - - 16G -
/dev/sda1 partition - - 83 500M /dev/sda
/dev/sda2 partition - - 8e 16G /dev/sda
/dev/sda device - - - 32G -
My goal is to end up with an image that has a 32G root
filesystem. To do that I use the command:
virt-resize --expand /dev/sda2 --LV-expand /dev/centos/root img-1.qcow2 img-1a.qcow2
# virt-filesystems --long -h --all -a img-1a.qcow2
Name Type VFS Label MBR Size Parent
/dev/sda1 filesystem xfs - - 500M -
/dev/centos/root filesystem xfs - - 15G -
The fact that /dev/centos/root (XFS filesystem) wasn't resized here
indicates that you don't have the correct XFS subpackage installed.
Virt-resize would have given you a warning about this, but in any case
you need to install the ‘libguestfs-xfs’ package on the host.
/dev/centos/swap filesystem swap - - 820M -
/dev/centos/root lv - - - 15G /dev/centos
/dev/centos/swap lv - - - 820M /dev/centos
/dev/centos vg - - - 32G /dev/sda2
/dev/sda2 pv - - - 32G -
/dev/sda1 partition - - 83 500M /dev/sda
/dev/sda2 partition - - 8e 32G /dev/sda

I then booted the VM and tries xfs_growfs on /dev/mapper/centos-root
and it doesn’t do anything but show me the filesystem geometry.
You shouldn't need to resize anything in the guest, virt-resize
should do it - see above.

Hi Rich,
Yup. That was it. I’ve submitted this on Bugzilla. Thank you.
