[Xen-users] About the limitation of "Physical RAM" to active guest VMs

["jowkju" <jowkju@xxxxxxxxxxxxx>]

Hi,

 

While I was using the XenExpress Version, I found that at most the only 4096MB of RAM can be allocated to active guest VMs.

Not to “a” guest VM, but to guest VM”s”. I knew it when I tried to install a new VM while a VM of 4090MB RAM was running.

 

my system has 16GB of physical RAM. Then, If I use Xen on my system, I should waste the rest 12GB of Physical RAM??

Is there any trick that active guest VMs can use more than 4GB of physical RAM?? (Except to buy a XenEnterprise or XenServer…)

 

Thank you.
