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: http://www.ovirt.org/OS_info#value_overriding let me know if it helps > On Tue, Feb 17, 2015 at 3:31 PM, Martin Pavlík < [email protected] > wrote: > > > Hi Punit, > > one thing is confusing me.
