Sure, let's call it something else, but this is a typical behavior expect=
ed
from the desktop/server property.=20
Well there could be property with different default values for desktop and =
servers, couldn't it? ;) Think about memory overcommit or default disk allo=
cation for example.
David
So what we are going to do is that remove the property and throw away
all=
the related data, while when (if ever) we get the new property (behaveAsDe=
sktop, notUsedWhenNotConnected, whatever we call it) the users of the syste=
m will set this property for the VM's that used to be desktops. We could sa=
ve that work for the users.
=20
Also, it may appear to be an edge-case, but for a good scheduling in my o=
pinion
this is important.
