Vista - allocating memory for VHDs in HyperV - i have no more memory

When I create a new VHD and allocate memory to it, is that memory now
dedicated to that VM while it's running?

I have a dual quad processor server with 32gig of memory running a
whole bunch of VMs. CPU is typically at around 1% usage. I need to
create 3 more VMs as we are using one VM per our customers and have
three more customers coming into production shortly. However when I
went to create a new VHD and allocate 4gig to it, I was told I'm out
of memory. I looked at what I had allocated to other VHDs and I guess
that would be correct.

So right now I have

parent OS - windows server 2008 data center
MS Dynamics CRM 4.0 - 2 gig (probably lower than it should be?) -
windows server 2003 standard
MS Exchange Server 2007 (8 gig) - windows server 2008 standard
application demo2 - 2 gig - windows xp pro x32
application demo4 - 2 gig - windows xp pro x32
ms sql server 2008 x64 - 4gig - windows server 2008 standard
customer application server 1 - 4 gig - windows xp pro x64
customer application server 2 - 3.5 gig - windows xp pro x32
svn - suse linux - 1 gig

So my issue is that I have tons of processing power and disk space
left for more VMs, I'm just out of memory. I believe 32gig is the max
this hardware will support.

I need to create three more application VMs and we typically use xp
pro x64 and allocate 4gig to them.

There's just no way to wedge that many OS's in without cutting down
how much RAM you have allocated to some of them, however you'd need to
cut down the other a whole 12G, so that may just be impossible. I'd
check to make sure your host is at it's maximum RAM, and if so, time
to buy another box.

ARGGH!!! Ok thanks. I emailed Dell, I currently have 8x4gig in it,
which
of course means if it IS upgradable, I have to pull the 4gigs and
replace
them rather than add to them. It sort of sucks to have all these
available
hardware resources and be limited by physical memory. I may have to
kill my CRM project for now in order to make room for production
applications.

I feel your pain -- it sounds like you have a nice machine, but not
quite enough RAM capability.

I heard back from Dell. It's upgradable to 64gig, but they want over
$8000 for 8x8gig.
The entire machine with 2x4 quad processors, 6x300gig 15K SAS drives
and 32gig was only $7000 shipped including tax (no OS).

I'm looking at 3rd party 8gig memory, and while I've found it cheaper,
I haven't found it cheap enough
to justify upgrading this machine vs. just buying an entire new
server.

enough for the 3 new VM's.
