Subject: Re: [ovirt-users] Cannot run VM. Memory size exceeds supported limit for given
cluster version.
Hi Martin,
Sorry....i am referring VM64BitMaxMemorySizeInMB....and creating ubuntu 14.04
LTS 64 Bit...
the problem is that if you choose any linux distribution (ubuntu/debian/sles..)
in the 'OS' drop box for the vm (except ones specifically mentioned 64bit like
freebsdx64/rhel_6x64..),
it will be considered as 32bit.. and thus the 32bit limit apply.
there is an open bug on that:
Bug 1133642 - [RFE] Change the default "Other OS" to be 64bit instead of 32,
affecting the derived OSes like Ubuntu
you can work around it by:
1. select another 64bit os that is suitable for you, like freebsdx64
2. override the os-info file, adding your own 64 bit version os, or making existing one
64bit
here is how to do it:

let me know if it helps

Hi Punit,
one thing is confusing me. You refer to VM32BitMaxMemorySizeInMB, but you are
working with 64bit VM/template. Shouldn’t it be VM64BitMaxMemorySizeInMB?
Anyways both should allow for approx. 64GB of memory. If you create VM with
63GB (or closest lower amount) it works?
Could you provide relevant part of engine.log, vdsm.log, supervdsm.log and
libvirt log? From the time when the error occurs?
