Unable to lock 6144MB physical RAM: Resource temporarily unavailable

[Rajeev jain]

I reconfigured a VM (vm4) from 4GB to 8GB memory. There seems to be enough free memory available but I can't start the VM after adding 4GB memory. The VM works fine I switch the memory back to 4GB.

Shalom,

Recommend checking memory allocation to other guest systems. There may be a problem with the amount or location of memory in use buy other guest machines.

I have attached the hpvmstatus output above which shows how much memory is allocated to each guest. The host has 32GB physical memory.

Hi Rajeev jain,

Could you please post a kmeminfo output from the host if you have it installed, if not you can download from:

ftp://eh:spear9@hprc.external.hp.com/memory.htm

also the output from:

#swapinfo -atm
#hpvmstatus -s


Thnx

Sorry to change the host here but I am still having the same problem. The VM fibak works fine but I cannot even start nfsvm because of low memory.

Hi,


10% of the Physical Memory is to be used by VMHOSTS.

What is the SwapMemory using by VMHOSTS.

if it is less increase the Swap memory for
VMHOSTS & Then try to start.

[Rajeev jain]

not sure how the swap will play a role here, i do have 16gb swap allocated to each VM and 32gb for HOST server.

what you mean by I could use only 10% of physical memory for VMs?

[Prashanth.D.S]

Hi Rajeev,

It is important to understand that VM guest should be started in supported configuration...

Swap space equal to 1.5 times the size of physical memory for ALL GUESTS.

setting swapmem_on to ZERO which disables psuedo-swap

Note that HPVM installation sets swapmem to "0" and it this setting must be maintained. (In other words, do NOT set swapmem to "1".)

Best Regards,
Prashanth
