XenServer - Check for free space before snapshot-actions

As several times reported on the citrix forum:
http://discussions.citrix.com/topic/293667-original-vdi-unavailable-after-revert-snapshot-failed/
Whatever happened, but XenServer should take care of enough free space before doing anything.
It must not happen, that something is deleted and unbootable if it could be prevented by simplest checks.

        Hi Tim!
        I tried to use the space on my local HDD (LVM, not ext3) via snapshots...
        I can make several of these without consuming the space of my HDD.
        LVM should reserve/take the full HDD-size and doesn't grow. so I'm asking myself, how it works, that I've taken several Snapshot of 300 GB HDDs (with little differences) on my 900 GB HDD.
        I will have to test that with another Windows VM, instead of the linux one and try to fill the Disks between.

        Christof,

        Please validate if the issue remains in the XenServer Creedence Alpha on xenserver.org, and if so please do enter an incident at https://bugs.xenserver.org.

        guys at citrix need to pay attention to stuff like this ! after citrix acquisition Xenserver has dropped behind Microsoft hyper-v !
        hyper-v architecture closely resembles Xenserver?
        Citrix seems to put XS on a slow death path from where it was a compelling option in 2008 against vmware & hyperv
