I installed a 32 bit Windows 2003 enterprise edtion domU. xm list
shows the domU has 7G RAM. But Windows 2003 shows only 3.75G RAM. I do
not know what''s wrong. Anyone knows?

Anyone knows?That is wrong: 32 bit Windows 2003 A 32bit Windows only can use up to 4 GByte without PAE, and even with PAE processes are restricted to 2 GByte (or 3 Gbyte in some cases). If you really want to give a Windows Installation more than 4 G, use a 64bit version.

RE: [Xen-users] Re: Windows 2003 domU can not use 7G RAM ?
Zu is using Server 2003 ENTERPRISE. It supports at least 8GiB of RAM. Klaus is correct about the processes'' memory limits, and the PAE. The /PAE suggestion offered up by James might have already done the trick for Zu, or it might be that Xen domUs don''t support PAE... Anyone have a technical answer on the Xen side?
