OMV 0.4.38 - 2.6.32-5-amd64
latest VB plugin from stable (OMV-plugins)
I have a VM that I use to host ownCloud and Subsonic services. Machine virtual disk is dynamic with an original limit of 10GB (I've since raised it to 15GB), as are all my VMs. I have attached 2 vdi's; 1 for OC (100GB) and another for Subsonic (200GB). Both are nowhere near capacity according to Debian:
root@owncloud:~# df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 9.4G 2.2G 6.8G 25% /
udev 10M 0 10M 0% /dev

/dev/sdb1 99G 4.4G 90G 5% /var/www/owncloud/data
/dev/sdc1 197G 62G 125G 34% /home/subsonic/media
I know it says host but under settings in phpVirtualBox, guest system vdi shows a virtual size of 10GB and an actual size of 9.43GB. I have other VMs with same vdi limitations whose actual size are in correlation with what is seen in the guest OS and at most 30% disk space used. I don't foresee this being an issue anymore as I have expanded the vdi to 15GB but am curious as to why the actual and virtual sizes were so close on this particular VM. There's nothing stored on the system drive and I never write any data to it since I've had the VM set up which is going on 9 months now.
FWIW here is vbox.log that shows the initial suspension, me trying to start vm and then eventually powering off:

Also note that my storage vdi's for OC and Subsonic live on /dev/mapper/500BLUE-storage and not dev/mapper/500RE4-vbox which hosts the vm itself and system vdi.
