<![CDATA[Error on attempting delta backup -- how to rectify?]]>Been using XO with delta backups for a while however one of my VMs is now receiving an error and I'm not sure how to rectify. I'll post what I have below. Looks like there might be two errors -- VHD check error and WaitObjectState Error. Not sure how to actually fix any of these errors.

Thanks for help.

     Clean VM directory
    VHD check error

My VM not working is a pfSense VM. I looked at the link posted and didn't see BSD drivers. Looking my XO installation for pfSense I dont even see anything in the GUI regarding healthchecks. Weird. Not sure how this option was even turned on in the first place.

Otherwise it'll timeout.

Can you confirm that the drivers are installed and running?

I would suggest manually restoring the VM from backup and attempting to start it to see what information is given in the console.
