  How do you change the “memory required to start VM” dynamically? I know the command “hpvmmodify -P VMname -r 2G”. I know you need to install HPVM-guest, I know you need to enable dynamic_memory_control=1. But it doesn’t work.

  Since lack of information from your question, please try to verify the following point.

  1. Did you installed guest-tool properly on your guest vm?
  2. hpvmstatus -V -P VMname , did you see dynamic memory section is enabled?
  3. Did you create your VM with -x ram_dyn_type=any -x ran_dyn_min=M -x ran_dyn_max=M -x ram_dyn_target_start=M ?
  4. hpvmmgmt -l ram , on guest, does it show memory settings properly?

  Try to re-read the manual carefully again.

  good luck!

  Hello,

  1) HPVM-Guest is installed
  [VMname:root]/root # swlist HPVM-Guest
  # Initializing…
  # Contacting target “VMname”…
  #
  # Target: VMname:/
  #

  # HPVM-Guest B.04.00 Integrity VM Guest
  HPVM-Guest.vmTools B.04.00 Integrity VM Tools

  2)[Dynamic Memory Information]
  Type : driver
  Minimum memory : 1024 MB
  Target memory : 2042 MB
  Maximum memory : 2048 MB
  Current memory : 2042 MB

  [Dynamic Memory Information]
  =======================================
  Type : driver
  Target memory : 2042 MB
  Current memory : 2042 MB

  The command I did to change the memory is

  [host:root] # hpvmmodify -P VMname -r 3g
  hpvmmodify: Unable to dynamically set the memory information.
  hpvmmodify: Guest needs to be restarted for all changes to take effect.

  You can see that I need to restart the guest.

  Thanks.

  Hello,

  I think I found why. Because I didn’t create the VM with
  dynamic_memory_control=1, I have to add the option when change memory.

  hpvmmodify -P VMname -r 4g \
  -x dynamic_memory_control=1

  This command worked. But my additional issue is: I can’t
  see the changes from hpmvstatus command.

  Hi Steve, using dynamic memory on HPVM can be set between ram_dyn_min and ram_dyn_max. The ram_target specify the guest VM memory size, enable dynamic_memory_control is allowing the dynamic memory management on guest vm.

  you should set ram_dyn_max to a higher value, and then use ram_target to limit on each guest VM.
