Hi,

*urgently* clean up the disks. If you get a full disk qubes is likely to 
crash since some
config files are not written properly. I experienced qubes rendered 
unusable while the disk
was full. So some config files which manage the VMs got corrupted, so I had 
to boot kali
to mount the disk images and to backup all my data and then to reinstall 
qubes,
because dom0 did not wanted to start any vm, and reported some python 
errors in line xyz.
So debug the scripts or just reinstall :-(
Maybe, there is a better way, to repair qubes, but I chose the 
archeological approach,
as the success was guaranteed beforehand.

feature request: backup all config files into 3 archives and rotate them, 
so one can simply
exchange a broken state with the state before, while loosing some changes 
to memory size, net vm
and so on, but the system stays stable
/feature request.

So never ever let qubes fill your disk(s) completely. Leave some room.

Cheers

Ludwig
