RE: [Xen-users] windows guest and only showing 3.75 out of 8GB ram

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.

 

Thank you,

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
> > > 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,
