Hello guys, I have RHEL5. I want to install Windows XP on it using Xen. I heard I need PAE enabled processor. So I did the following: [root@server ~]# grep -i pae /proc/cpuinfo And I got this: flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc pni monitor vmx est tm2 xtpr flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx constant_tsc up pni monitor vmx est tm2 xtpr [root@server ~]# Does this tells that I have PAE enabled processor. One more thing I have 512 MB RAM (physical total RAM). So how much should I give to the Virtual Machine and last thing the installation source in this case can be a CD or ISO image. Thanks in advance Regards Deependra -- Enjoy Life !

But 512MB RAM is too small on virtualization environment... dom0 and Xen need more than 256MB RAM. (RHEL5 configuration limit say 512MB) On native machine, is 256MB RAM for WindowsXp too small?

PAE gives you support for lotsa RAM, up to 64 Gbytes. What you need is the virtualisation capability in new Intel and AMD processors. -- Cheers John -- spambait 1aaaaaaa@coco.merseine.nu Z1aaaaaaa@coco.merseine.nu Please do not reply off-list

You can use either CD or ISO - I prefer to use ISO as it''s simplier.> Thanks in advance > Regards > Deependra > > > -- > Enjoy Life ! > > -- > Fedora-xen mailing list > Fedora-xen@redhat.com > https://www.redhat.com/mailman/listinfo/fedora-xen

Obviously the more the merrier but if he''s only got 512 to work with ........> > Best Regards, > > Akio Takebe > > -- > Fedora-xen mailing list > Fedora-xen@redhat.com > https://www.redhat.com/mailman/listinfo/fedora-xen
