I wonder what is the maximum memory allocated with Xen 4.3 for windows . Is everyone just allocating 4 - 6 GB or more. I had been testing with opetron e2320 and the system has 32 GB of ram so I had failed at assigning more than 6gb. I use windows 2012 upstream qemu. Server 2012 will not boot with anything more than 6gb.I wonder if any of guy had managed to assign more than 6gb. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
So is no one using xen or no body has any issues with memory limits ? It xen limited to only 6 gb of ram per vm ? I am unable to assign anything above 6 gb KVM does not have any problem but xen will not let me assign more than 6 gb to vm machine. I use xen-4.3-git On Tue, Jul 30, 2013 at 6:59 AM, jacek burghardt <jaceksburghardt@gmail.com>wrote:> I wonder what is the maximum memory allocated with Xen 4.3 for windows . > Is everyone just allocating 4 - 6 GB or more.

What exactly is the error you are seeing? I have a hardware bug that prevents me from using more RAM than the lowest BAR with PCI passthrough (which in my case happens to be 2688MB), but without PCI passthrough I can easily set the VM for 8GB or 16GB and it just works. Are you using PCI passthrough? What are your dom0 and domU E820 maps?

I have couple of amd based systems. I have opteron 2373 e with 32 gb of ram
and it will not let me assign 12 gb of ram. The most I could assign is 6GB

From what you pasted below, it looks like something to do with NUMA is failing. Have you checked that Xen 4.2.x behaves the same way?

Well I got this solved I just increased both videoram = 128 shadow_memory = 128 and I had no problems assigning 12 gb of ram to vm. Well maybe we need patch that will give error message about not enough video memory assigned.
