I opened a bug of xenU failed to create with shadow mode enable.

http://bugzilla.xensource.com/cgi-bin/bugzilla/show_bug.cgi?id=85
<http://bugzilla.xensource.com/cgi-bin/bugzilla/show_bug.cgi?id=85> 

Is there anybody have any idea of it?

 

I also opened a bug about xenU failed to destroy after violate break xm
migration process.

http://bugzilla.xensource.com/cgi-bin/bugzilla/show_bug.cgi?id=84
<http://bugzilla.xensource.com/cgi-bin/bugzilla/show_bug.cgi?id=84> 

Does anyone meet that before?

 

 

Thanks,

Subject: [Xen-devel] failed when boot the domain with shadow mode
enabled

 

Hi, 

I tried to run the dom0 & domU with shadow mode enabled, but both are
failed. 
For dom0: 
1 Set opt_dom0_shadow=1 
2.Compile the dom0 kernel with CONFIG_XEN_SHADOW_MODE 
Then boot the system, but it failed in the function new_guest_cr3() when
get_page_type(). 

For domU: 
1.Compile the domU kernel with CONFIG_XEN_SHADOW_MODE 
When "xm create" the domU, it failed at the similar point as dom0,
because of get_page_type() failed. 

Is it a bug in shadow mode for dom0 & domU, or the way I start the dom
with shadow mode enabled is not right?
