1) mounted hard drives (external devices) randomly dismount and remount when VM is running
2) restarting the host OS: the restart is canceled by parallels
3) if you restart the VM, HDs that were previously mounted do NOT re-mount
details:
i have a mac mini running 10.9
this mac has several external hard drives connected
this mac runs parallels
in the guest OS, i run 10.6.8 Server
one of the external drives is mounted in the guest OS (via Devices->External Devices)
the server serves time machine to my LAN, using the mounted drive from the host OS
periodically, the drive simply dismounts without warning, then shows the "The disk was not ejected properly" error, then the drive re-mounts (auto-dismissing the error dialog) but the drive now has a different mount-point name (has a "1" appended). the new mount point name breaks Time Machine.
this problem occurs daily.
problem 1
here are some screen shots of the situation:
above: time machine failing is the first indication i have of the problem
above: note the incorrect mount point name
above: i am about to (correctly) dismount the drive, it should not be a problem, right?
above: dismounting the drive should NOT cause this problem
re-mounting the drive, it now has the correct name
now time machine works again
problem 2
if i restart the host OS, the restart is HALTED because parallels cancels the restart while it suspends the VM. the restart SHOULD NOT BE HALTED
problem 3
if i suspend the VM, then quit and re-run parallels, and the VM is launched again, the HDs that were previously mounted DO NOT GET RE-MOUNTED. All discs that were mounted during suspend (or shutdown) should be re-mounted when the VM comes back online
