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')
0x11575 pages is a 277M ramdisk, which, as the message says, is really
quite large. Especially compared with the 64M of RAM which you have
configured the guest with.

Ian.


OK, I changed the "memory" line to 800, but, seems it does not work also:

zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$ sudo xm cr -c 1-pv.cfg
Using config file "./1-pv.cfg".
zhiyuan@zhiyuan-ThinkPad-R400:~/xen_work/images/rhel51-pv$ Error: Device 2049 (vbd) could not be connected. Path closed or removed during hotplug add: backend/vbd/1/2049 state: 1

and quite silently .....

But I am very sure the disk image path is correct. And tried also to change "sda" to "hda" the result is the same.

I also attach the .config file for the pvops kernel with this email. Should I compile another kernel for the PV domUs?



Thanks!
Zhiyuan
