Paging File -- Windows 2012 R2, HyperV host & guest OS ?

Last Modified: 2015-07-24
Both of the below links act like you should "leave the
Windows 2012 default of system managed pagefile on the
C drive if you do NOT have issues"

Does anyone disagree ?

If so, what is your recommendation ?
https://support.microsoft.com/en-us/kb/2860880 says
For Windows Server 2012 R2 Hyper-V, the page file
of the management OS (commonly called the host OS)
should be left at the default of setting of
"System Managed." This is per the Hyper-V
product group.

http://windowsitpro.com/hyper-v/hyper-v-pagefile-configuration says
Windows Server 2012 changed this; the system managed
pagefile is intelligent and by default will ensure
that the pagefile is at least big enough to capture
a kernel memory dump but isn't the size of the
complete memory. If the system experiences a bug
check (blue screen), then for the next four weeks
the pagefile will be increased in size to match
the amount of memory. This ensures that if a bug
check occurs again, the entire contents of memory
can be captured; after the four weeks has passed
(the date of the last bug check is stored in the
registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
\Control\CrashControl\LastCrashTime), the pagefile will
shrink back to the smaller size. Jeff Hughes documents
this in the blog post "Windows 8 and Windows Server
2012: Automatic Memory Dump."
