1) There is an ugly problem for pv_kernels: thay can not raise memory above value at start time.
2) XCP use dynamic memory technology, intended for -xen kernels (not PV), so they use dynamic-min, dynamic-max values to regulate domain memory automatically.

Quick and dirty solution:

shutdown VM and set memory-static-min to same value as memory static max (all 4 values can be changed by 'xe vm-memory-limits-set')

Hi,

I have 5 XCP servers joining a pool.

I have more than 16G physical RAM free and when I tried to allocate 16G RAM for my CentOS VM using:

xe vm-param-set uuid=my-vm-uuid memory-static-max=17179869184

xe vm-param-set uuid=my-vm-uuid memory-dynamic-max=17179869184

and when:

# free -m //on my VM

the total was: 6130

and if:

# free -m -t

Total 11698

why it is not 16G?

Thanks for you help
