Our VM person asked me to ask the wisdom of this August assemblage the
following:

------------------------------------------------------------------------------------------

Well I have some questions about the use of V-DISK space.  According to
documentation V-DISK space is sharable & in fact I have defined V-DISK
space for one VM using this User Directory statement:

MDISK 300 FB-512 V-DISK 256000 MWV

Documentation states that the V-DISK space is created when the first user
links to it (logon & format) and it is destroyed when the last user
detaches from it (logoff).  If I add this same statement to all the Linux
User Directory entries will they all attempt to share this area?  If so
that has implications on when you format this area, as only the first Linux
will need to link & format this space.

I can't find a definitive answer for how this gets used.  Perhaps you can
find out.

1)  V-DISK blocks appear to be 512 byte blocks & are created in 8-block
pages.  True?

2)  Will all Linux guests, that contain "MDISK 300 FB-512 V-DISK 256000
MWV" share the same V-DISK space?  If so is one 256000 block area allocated
& shared or (256000 x #-of-Linux's) allocated & all shared?

3)  How will you automatically know when a given Linux is the first and
therefore needs to format the area, if area(s) are shared?

4)  SuperValu Red Paper suggests V-DISK size 15% of VM size, what's up with
this formula 2 x VM size + 32M ??
