RE: [Xen-devel] GPLPV memory ballooning and x32

I tried the Xen3.4.2 from the Gitco repo. I am unable to bring up any domain if 
I specify the memmax option to be greater that memory. The respective qemu-dm 
processes for the domains are at 95-100% CPU utilization. I tried this with x64 
Linux and Windows domains. The Linux-centos domains stayed at "Booting 
'CentOS'" screen. The windows domain died with a GPF that was displayed in the 
VNC window. I have attached the screen shots. I did not find anything of note 
in the xend.log. The qemu logs are shown below. The last line in "xm dmesg" is:

(XEN) io.c:199:d5 MMIO emulation failed @ 0008:4013c8: 90 a6 9f 2d 08 83

Any idea why this is occurring?

Thanks,
Aravindh
