We're running a few virtual machines on KVM-QEMU.

We have some images set up that we just clone when a new machine is needed.

Normally I run virt-clone -o win-xp -n --auto-clone However today when setting up a CentOS machine we're getting an error: WARNING The filesystem will not have enough free space to fully allocate the sparse file when the guest is running. 20480 M requested > 9901 M available

With the other virtual machines the .img files are symbolic link pointing to space in /dev/ (i.e. /dev/dm-0 /dev/dm-1 /dev/dm-2 etc). The .img files are stored in /dev/vg_storage_pool/

In this instance, the newly cloned machine (I cancelled the process) was creating an image in /dev/vg_storage_pool/ and not using a symbolic link.

Does anybody know what could be causing this problem?
