yesterday it was like:

I wanted to bring down xx-cie203 memory from 7G to 6G

#hpvmmodify -P xx-cie203 -r 6G

The mistake I did is instead of using small r I used R (upper case R)
hpvmmodify -P xx-cie203 -R 6G
It executed the command.
In man hpvmmodify I found -R is for reserve mem and -r is for memory

now when i start the vm guest it gives me the error

any suggestions?
The vmguest should start after I reduced the memory.#
But earlier because of using -R ...is this the reason vmguest is not coming up?
If yes..how to undo the changes ?

much need help..awaiting..

Masood,

Check one of your other VM's:

hpvmstatus -P xx-cie101

and check for Reserved Memory value there (I think 64Mb is default). If so just hpvmmodify again:

hpvmmodify -P xx-cie203 -R 64M

Richard...
yeah you were right...Before I saw your reply I was thinking that may be I should change reserve mem to its old value.. but i was not sure what its old value is...

so I did -R 512M
Then I saw your suggestion to change it to -R 64M (default)

However as it worked for -R 512M I didnt changed it again...

By the way..
(1)where can I see reserve mem?

(2) By using "-P vmguestname -R 6G" did i changed VMguests' reserve mem or VMhosts reserve mem?

(3)
hhln-b00-cie203:/ # swapinfo -tam(after -R 512M)

total 22520 2011 20509 9% - 0 -
hhln-b00-cie203:/ #

Where is the reserve mem? 640M?

However for your valuable answer and quick response I am assigning points to you...

You can list it with:

hpvmstatus -v -P hpivirtual

Great.

Yeah..I see all my vmguests have 64M as reserve mem..
and the guest on which I worked shows 512M because I did -R 512M

Thats okay I suppose anyways
Thank you Richard and orange!

The default reserve memory is 64Mb
