[Xen-devel] Cannot start up HVM guest when maxmem is not equal to memory and HAP is enabled.

Hi all, 

On my production deployment with xen-3.4.4-rc1, HVM guest would not start up when maxmem is set not equal to memory, unless HAP is disable(hap=0). The guest just hangs at 'Booting from Hard Disk...' as shown in the attachment. I find that both Oracle VM and Fedora have the same problem per the following links: 


Could I ask if there is any work in upstream/xen-unstable to fix this problem? 


Below is the xm dmesg output related with the hvm guest:
