Starting guest: insufficient host swap resources for this guest

[Kasper_USB]

The following happens:
soravx1:/# hpvmstart -P vm-P-1
HPVM guest vm-P-1 configuration problems:
Warning 1: There are insufficient host swap resources for this guest.
These problems may prevent HPVM guest vm-P-1 from starting.
hpvmstart: Unable to continue.

Can't start vm-P-1.

If i change the Memory
soravx1:/# hpvmmodify -P vm-P-1 -r 1G
soravx1:/# hpvmstart -P vm-P-1

runs good.

what is the problem and how can i solve it ?

Shalom,

This sounds like an OS problem in the guest.

Swap must be set to minimum 50% of RAM or HP-UX might not want to boot.

If this is the case the guest may need to be re-installed.

What is your VMHost config ?

How much ram ?

How much swap is configured ?

Well you have what appears to be 132GB RAM, and only 49GB swap:
dev 25165824kb
dev 24576000kb
You have to configure enough physiacl swap space on the VM Host to cover the total memory to be used when starting your VM Guests.
In your case each VM has 40GB RAM, so you need a MINIMUM of 84GB (40 + 40 +4 for the host)
All documented in the HP IVM Manuals

With psuedo swap turned off on the Host ( It must be turned off ), you need to configure the VMHost correctly.

Please review the IVM admin guide.
