Vista - Hibernation on virtual pc?

We had a terrible storm last night and all today and it awoke me in the
early morning with a very loud series of thunder claps. I decided I would
shut down the computers although they are on managed APC UPS. I had VPC with
Vista Ultimate running. It took a very long time to shut down because I have
undo disks on and it takes a long time to save state when it has been
running for a week. While I was waiting for it to finish and shut down, so I
could shut down the host, I got to thinking about how would this be handled
if the electricity had gone off and my UPS took over.

I have the host XP Pro on Hibernate and APC's PowerChute software manages
the shutdown. But what happens if the guest Vista machine is running also
and the power goes out? I can't find hibernation on Vista. Would the guest
be saved in hibernation state of the host?

Anyhow, would PowerChute shut down the guest with no time for it to save
state or what? I had not thought about it before now. I've had APC UPSes
for many years but I only started using hibernation and the Power Chute
software recently.

Also, if I shut down manually when there is a storm, I am not clear about
what choices there are except save state or don't. As save state takes a
long time is there a choice besides don't save? So that I could shut the
guest down faster so I could shut the host down quickly if I think there may
be a power outage at any moment? (I hate the way Vista takes forever to
shut down even when undo disks is not used. I think XP and Vista should be
like 98SE and shut down instantly when told to do so and neither do that.
Vista takes forever).

If you hibernate the host, you should not have to do anything to the guests;
they should come back exactly as they were before the hibernation (VPC is just
like any other application).

See this link for how to reactivate the hibernate option in Vista:

http://www.howtogeek.com/howto/windo...windows-vista/

[My understanding, possibly wrong, is that Sleep in Vista is a combination of
Standby and Hibernate in XP; the hibernate file is created, and the computer is
put into standby. Under normal circumstances it resumes quickly as from standby,
but if the power fails it will resume as from hibernation.]

--->David:

I took some finding, but there actually IS a link in Vista Help and
Support m(search for "hibernation") that will tell you how to do it
though using a command:

Start -> Run (as administrator) -> "powercfg -h ON" without the quotes

The same H&S page displayed will also have a simple link marked "Click
hee to re-enable hibernation".

I set mine to ON, which then allows the offering of 'hibernation' on the
Start -> Shut down button.

Mine kept disappearing and I'd have to keep setting it to ON until I
found out that running the disk cleanup utility AND checking the
'Hibernation File cleaner' would reset this option. Duh!

news:eQAkgSBaJHA.5108@xxxxxxThat's good to know.I think the Power Plans in Vista are ridiculous and very difficult to work
with. Power options for all previous versions of Windows were understandable
and easy to work with (although Power Options for 98SE was rather buggy). I
have no Sleep or Standby options for the "Plan" I chose which is HIgh
Performance. I also have no hibernation. My choices are to manually shut
down and that is it except I could set the monitor to shut down after 5
minutes of inactivity and I find that does not work reliably in Vista. It is
VERY reliable in XP though.

There are a bunch of Advanced choices ALL having to do with laptops. The
Vista Help file assumes that a user has a laptop and does not mention Power
Savings settings for desktops. It is confusing, difficult and very round
about to properly set a desktop running Vista with Power Savings. Plus,
there is NO hibernation for a desktop that I can find. ALL references to
sleep, on battery, when to shutdown, etc. in the Vista Help file refer
exclusively to laptops. I find that astounding and insulting. I hate
laptops. I want help on how to use Power Savings in Vista for desktops.

news:%23J8BG1DaJHA.4424@xxxxxxI did the "powercfg -h ON" command. I had to open a command window and do
it there and I found the problem! It says:

Hibernation failed with the following error. The request is not supported.

The following items are preventing hibernation on this system:

The system firmware does not support hibernation.

There are one or more legacy drivers installed:
1-driver- vmsrvc
vpc-s3

vmsrvc is virtual machine additions. vpc-s3 appears to be a battery for
Sanyo digital cameras which I don't have so that one puzzles me. Obviously,
hibernation with VPC is done via the host machine only if there is a power
outage and you have software to manage shutdown and put the host into
hibernation.

news:#OAgD1MaJHA.5488@xxxxxxIn this case I think that it is more likely that vpc-s3 refers to the
driver for the emulated video card in the vm (which is an s3 trio).

--->Yes. I think so also. I can see a driver called that too.

--->Meleleina:

I agree wholehearted with you. For some unknown reason Vista assumes it
is on a laptop. My other pet peeve is that Vista also assumes that you
are using a WIRELESS network connection. When I plug in the CAT-5 cable
after turning off the wireless transponder Vista complains mightily that
it has NO network connections. I have to reboot before it can "find"
the hardwired connection - and, it still names it as the 'wireless'
connection. Just plain stupid.

news:OVfnmpQaJHA.4424@xxxxxxI should have thought of that. I think both of you are right. I had
forgotten what the emulated video card is called or I would have realized
what that was referring to as "vpc" at the beginning is referring to virtual
PC...but "s3" rang no bells in my mind. I'm glad to know why I couldn't
find any hibernation button.
