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 !
