Starting vm client insufficient free host memory

[Karen Birkelbach]

I am trying to create an additional VM client on my VM host server, but get the following error:

vm1# hpvmstart -p9
HPVM guest vmc9 configuration problems:
Warning 1: There is insufficient free host memory for this guest.
These problems may prevent HPVM guest vmc9 from starting.
hpvmstart: Unable to continue.

I'm not sure if I've got everything calculated properly, but I'm pretty sure that I've got enough physical memory to handle this. Any assistance is appreciated.

Use

hpvmstatus -s

to see the available memory.

The host itself needs to have memory for each guest.

[melvyn burnard]

Well looking at what you have set up, and using the calculations to check memory, I think you should be ok.
However, you should remember that there needs to be memory kept in resevre for the Host, as well as a certain overhead per guest.
From the VM3.5 manual:
Sufficient physical memory (RAM), including the following:
750 MB + 7.5% of memory beyond the first GB (that is, 7.5% of (total physical memory
- 1 GB))
Total aggregate memory required for each guest (operating system and application
requirements)
Additional 7% of aggregate guest memory for overhead for guests less than or equal
to 4 GB and between 7% and 7.3% for guests larger than 4 GB.

[Karen Birkelbach]

So, if I'm looking at this correctly, there's only 1GB available to create any VMs?

#hpvmstatus -s
[HPVM Server System Resources]

Processor speed = 1599 Mhz
Total physical memory = 98105 Mbytes
Total number of processors = 12
Available memory = 1026 Mbytes
Available swap space = 60065 Mbytes
Maximum vcpus for an HP-UX virtual machine = 4
Maximum vcpus for a Windows virtual machine = 4
Maximum vcpus for a Linux virtual machine = 4
Available entitlement for a 1 way virtual machine = 1599 Mhz
Available entitlement for a 2 way virtual machine = 1599 Mhz
Available entitlement for a 3 way virtual machine = 1599 Mhz
Available entitlement for a 4 way virtual machine = 1599 Mhz

[Torsten.]

You are right:

Available memory = 1026 Mbytes

[Torsten. · Accepted solution]

From the version 4 manual:

Sufficient physical memory (RAM), including the following:
â ¢ 750 MB + 8.5% of memory beyond the first GB (that is, 8.5% of (total physical memory
- 1 GB))
â ¢ Total aggregate memory required for each guest (operating system and application
requirements)
HP-UX 11i v2 May 2005 requires a minimum of 1 GB of memory, so a guest running
HP-UX must be configured with at least that much memory.
â ¢ Additional 8% of aggregate guest memory for overhead for guests less than or equal
to 4 GB and between 8% and 8.3% for guests larger than 4 GB.
For example, for a VM Host with 16 GB of memory and two VMs configured with 3 GB
of memory each, the memory requirements would be calculated as follows:
â ¢ 2 GB for the VM Host (750 MB plus 8.5% of 15 GB)
â ¢ 6.48 GB total guest requirement (108% of 6 GB)
â ¢ Total requirements = 8.48 GB of memory
This leaves 7.52 GB of memory for additional guests.

I believe I understand it now. Thank you for your assistance! That server will be getting additional memory. My VM's will go on another server that has enough available memory for now.

[Karen Birkelbach]

I was able to add my VM's to other servers. I have learned how to determine resource availability for other VM's now. Thank you for your assistance.
