Hyper V Host machine PANIC after increasing RAM

Question

Hi

I have Dell PowerEdge R620 Windows Server 2012 RAM of 64GB

In Hyper V I Installed Redhat 6.0 with initial configuration and Redhat installed successfully

I assigned 30 GB RAM and 18 virtual processor to the virtual machine after assigning the host machine not responding , It is allowing upto 8 GB and after increasing RAM it goes panic attack

PANIC: early exception 06 rip xxxxxxxx error 0 cr2 0

and my question

Is it possible to assign 30 GB RAM hyper v machine if so how it is possible??

Thanks in advance

Hi,

Is this a new install of the OS? Are there other virtual machines running? The issue may be with NUMA memory management and the version of RHEL 6 not working properly with it and the amount of memory allocated is requiring more than one node. http://technet.microsoft.com/en-us/library/dn282282.aspx

Try the following to see if it works.

Add the following Non-Uniform Memory Access (NUMA) kernel start parameter:

NUMA=off

And enable dynamic memory in the Hyper-V settings for this guest.
