VM no not start

[Gerardo Ramirez H.]

The last boot message is :

hpvmdynmem: unable to reach target memory size of 2106 MB after 60 seconds, resulting memory size is 5370 MB.

Thanks for your comments and help

I am usig T2767CC B.04.20.05 Integrity VM

[melvyn burnard]

As the message says, there is insufficient memory available to reach the targeted amount. Reduce the memory config in the VM, or check where you can reduce memory from any other vm's running

Thanks for your comments

The issue is that I have a BL890 with 80GB RAM, only one VM with 18 GB and the problem persist.

I am loking for last VM Patches

I will keep you informed

It's a known problem with unpatched V4.2.5.

The problem is indirectly caused by HPVM V4.2.5 enabling HPVM dynamic memory feature by default. The default values of ram_dyn_target_start and ram_dyn_max can default to 2G which, in the case of a larger memory guest, will not be enough memory for the guest to properly run or even boot.

The problem is resolved in HPVM V4.2.5 Day1 Core patch PHSS_41190 (or later). Make sure to install the latest HPVM patches immediately after updating HPVM.

Note!
If the guest boot was already attempted before the patch was installed, installing the patch by itself will not prevent the problem and reconfiguration of dynamic memory settings is necessary for the guest
to be able to boot again.

As a workaround HPVM dynamic memory can be disabled by
# hpvmmodify -P ${guest_name} -x ram_dyn_type=none

The manageability features for HP-UX guests brought by enabling HPVM dynamic memory can safely be re-enabled once PHSS_41190 (or later) has been installed by
# hpvmmodify -P ${guest_name} -x ram_dyn_type=any

If ram_dyn_target_start and ram_dyn_max have already been set, then you need to change their values to the desired range dependent on the configured memory size.

It's recommended that ram_dyn_target_start (and ram_dyn_min) should not fall below 25% (or 1GB whichever is higher) of memory configured for the guest. ram_dyn_max should be set to the memory configured.
