Re: [Xen-devel] Xen-4.1-unstable hypervisor booting error

[Michal Novotny <minovotn@xxxxxxxxxx>]

Thanks a lot Boris, adding dom0_mem setting to 1G (1024M respectively) 
made it working fine so I guess there's a wrong default setting for 
dom0_mem, at least for x86_64 architecture.
Thanks again Boris!
