[PVE-User] qemu write cache mode

[Dhaussy Alexandre]

Hello,

I just spotted something strange with storage cache mode.

I set cache=none on all my VMs (i believe this is the default), however 
qm monitor says "writeback, direct".

Am i missing something ?

root at proxmoxt20:~# qm monitor 198
Entering Qemu Monitor for VM 198 - type 'help' for help

     Cache mode:       writeback, direct
     Detect zeroes:    on

Process command line :
