comment Are there any good reasons for disabling hardware-assisted virtualization?
-1 The question is not about systems where HV is completely unavailable in the BIOS. It's about why it is shipped disabled, even though it's available.

comment Is there any any merit to routinely restore a linux system, even if unnecessary?
Yes, and additionally, returning to a base snapshot will may also wipe data that is still needed, such as logfiles, temporary files or result data. You could store this on a different partitions, but it still means extra work (and risk).

comment sync time on linux using ntp and persist it
Good point. Note that problems with the clock battery will only affect the RTC / hardware clock. The system clock used by the OS is maintained independently.

@JannePikkarainen: True, ntpdate does no good if there's no network connection, but hwclock does. You need to use hwclock if you want the correct time right after booting.

I took the liberty of expanding your already good answer a bit. Hope you don't mind.

ntpd alone will not help maintaining the time across reboots (it will only correct the time some seconds(?) after a reboot, and will not work if there's no net connection).

comment Server should shutdown when network connectivity goes down
I don't see how this could work. AFAIK, /etc/network/if-post-down.d/ is called if the network connection is shut down locally (by calling the approriate shutdown programs/scripts). It is not invoked if the network just dies for reasons outside the local system.

comment Is it possible for a TCP connection to remain open when the client has disconnected?
@joeqwerty: True, however the server could decide that it does not want to keep open a connection indefinitely, and could implement some timeout/close mechanism. That is what David Schwartz meant in his answer by "it is the responsibility of the application code". So the server can make a difference between a half-open connection and an idle connection if it wants to. To TCP however, there is indeed no difference between a half-open connection and an idle connection.
