[Xen-users] windows guest and only showing 3.75 out of 8GB ram
Hello all, We have a rhel5.2 dom0 64bit and a windows server 2003 32bit. I thought that adding the /pae switch to the c:\boot.ini file would allow me to take advantage of some more of the memory but that doesn''t appear to be the case. I had pae enabled in the config file but it doesn''t seem to make a difference. Is this an issue with my version of windows or something in my config? Any suggestions greatly appreciated. Thanks in advance! xen version: xen-3.0.3-64.el5_2.1 domU config file: name = "willy" uuid = "7af5d5f3-e67f-522f-0439-d89ecede6428" maxmem = 8192 memory = 8192 vcpus = 4 builder = "hvm" kernel = "/usr/lib/xen/boot/hvmloader" boot = "c" pae = 1 acpi = 1 apic = 1 localtime = 0 on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" device_model = "/usr/lib64/xen/bin/qemu-dm" usbdevice = "tablet" sdl = 0 vnc = 1 vncunused = 0 vnclisten = "0.0.0.0" vncdisplay = "14" disk = [ "file:/guests/willy.img,hda,w", ",hdc:cdrom,r" ] vif = [ "mac=00:16:3e:53:12:80,bridge=xenbr0" ] serial = "pty" Best regards, J.

What version of server 2003 32-bit? Standard and Web do not support PAE. http://msdn.microsoft.com/en-us/library/aa366778.aspx Either way, I recommend 64-bit. As you can see from the above link, 32-bit’s memory support is locked down in Standard and Web. In my mind, there are very few reasons to still be installing 32-bit operating systems.

Very good info Nathan and everyone. Thanks for the pointer. You are right of course. Let me get some 64-bit media and give it another go. Best regards, J. D.
