hi all,

I had installed Xen-4.0 in my Ubuntu desktop (Maverick Meerkat, 10.10) according to https://help.ubuntu.com/community/Xen

although, I had to replace grub 2.0 with old version to make everything work.

After rebooting, I want to create a PV guest with old method I had used in Xen 3.4.2. However, I got the following messages, and the creation failed.

zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$ sudo xm cr -c 1-pv.cfg
[sudo] password for zhiyuan:
Using config file "./1-pv.cfg".
Error: (4, 'Out of memory', 'xc_dom_alloc_segment: segment ramdisk too large (0x11575 > 0x4000 - 0x1b8f pages)\n')
zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$

The configuration file is attached with this email.

BTW, I booted the system with xen_commandline: dom0_mem=1024M sched=credit

and my box has 2GB memory, Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz processor.

Thanks in advance!
Zhiyuan
