+SSH to the kvm server and resize the guest's logical volume. If you::
+  want to be extra careful, make a snapshot of the LV first:
+  +
+....
+lvcreate -n [guest name]-snap -L 10G -s /dev/VolGroup00/[guest name] 
+....
+  +
+  Optional, but always good to be careful
+. Shutdown the guest:
++
+....
+sudo virsh shutdown [guest name]
+....
+. Disable the guests lv:
++
+....
+lvchange -an /dev/VolGroup00/[guest name]
+....
+. Resize the lv:
++
+....
+lvresize -L [NEW TOTAL SIZE]G /dev/VolGroup00/[guest name]
+
+or
+
+lvresize -L +XG /dev/VolGroup00/[guest name]
+(to add X GB to the disk)
+....
+. Enable the lv:
++
+....
+lvchange -ay /dev/VolGroup00/[guest name]
+....
+. Bring the guest back up:
++
+....
+sudo virsh start [guest name]
+....
+. Login into the guest:
++
+....
+sudo virsh console [guest name]
+You may wish to boot single user mode to avoid services coming up and going down again
+....
+. On the guest, run:
++
+....
+fdisk /dev/vda
+....
+. Delete the the LVM partition on the guest you want to add space to and
+recreate it with the maximum size. Make sure to set its type to LV (8e):
++
+....
+p to list partitions
+d to delete selected partition
+n to create new partition (default values should be ok)
+t to change partition type (set to 8e)
+w to write changes 
+....
+. Run partprobe:
++
+....
+partprobe
+....
+. Check the size of the partition:
++
+....
+fdisk -l /dev/vdaN
+....
++
+If this still reflects the old size, then reboot the guest and verify
+that its size changed correctly when it comes up again.
+. Login to the guest again, and run:
++
+....
+pvresize /dev/vdaN
+....
+. A vgs should now show the new size. Use lvresize to resize the root
+lv:
++
+....
+lvresize -L [new root partition size]G /dev/GuestVolGroup00/root
+
+(pvs will tell you how much space is available)
+....
+. Finally, resize the root partition:
++
+....
+resize2fs /dev/GuestVolGroup00/root
+(If the root fs is ext4)
+
+or
+
+xfs_growfs /dev/GuestVolGroup00/root
+(if the root fs is xfs)
+....
++
+verify that everything worked out, and delete the snapshot you made if
+you made one.
