Memory Allocation on a HPVM Guest

I have a total of 32 Gb Memory available on my host.

I have assigned 8GB to one VM. So now to the other VM what is the max. I can allocate.

could you please detail me with the calaculations...

from the below link

http://docs.hp.com/en/T2767-90180/ch02s01.html#install_reqs

total memory counts upto 26GB that I can allocate to the second VM, but It dosent boot when I allocate 26GB.

32Gb minus 8Gb would be 24Gb, not 26Gb -- so I don't see why you think 26Gb would work in the first place (the Host does need some memory and you'd be 2Gb into swap...)

From the link (and assuming v3 Host/ IVM 4.1 since that's what is in the link) what you really have left is:

32Gb - (32768*0.085 + 1250) - (8192 * 1.083) = 32768 - 4035.28 - 8871.936 = 19860.784 Mb.

Dividing that by 1.083 gives 18338.674 Mb.

So your second VM should be around 17.9Gb at most. 26Gb is much too large.
