[PVE-User] FreeBSD VM random high CPU/Disk IO

[Kris von Mach | Swishmail.com]

Hi Eneko,

No the VM never runs out of memory and doesn't touch the swap. The 
processes that start and deinit are dovecot processes, so they are very 
tiny.

pfSense probably doesn't do much Disk IO. So this issue might not show 
up. Our low use (atleast disk io wise) servers also run fine.

It's basically as if the Disk IO stalls momentarly and doesn't return to 
normal.

And so far it hasn't happened where more than one VM on the same host 
experiences this at the same time.
