Thread-topic: [Xen-users] RHEL 5.2 Xen Kernel doesn't detect all amount ofphysical memory
>From what I have read the XenServer distribution can support up to 32GB
RAM per VM and 128GB for the whole system. 

My guess is that unless a deliberate restriction is put in place the
limits RAM for RHEL5 Xen kernel then 256Gb RAM in total and 32Gb RAM per
VM is probably the max. 

Anyone know for sure?

Hello All,

Does anyone know what is the current status of RHEL 5.2 x86_64 with
respect
to the maximum amount of RAM detected by the Xen 64 bit kernel
(the one that shipped with Red Hat distribution )

In the following link
https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/en-US/RHEL5
10/Virtualization_Guide/ch-virt-hw-support.html
it states that 32GB of RAM is the maximum amount of physical memory the
Xen
kernel can detect. Is it still the updated status ?

Is there a work around or any other way to overcome this limit ?

Any info would be appreciated

Thanks,

Ido
