Re: [Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 11616

[Steven Hand <Steven.Hand@xxxxxxxxxxxx>]

Hi Ed, 

any chance you can test with debug=y ? The back-traces aren't 
really very useful otherwise. 

It'd also be good to know what the h/w platform is - AMD or Intel.

By '32bit' do you mean PAE? What guest is this? What's the guest
config? I cannot reproduce this myself on 11616...

This looks like the same bug to me, also cannot repro. 
Once more, guest + guest config info would be useful.

Hmm - when you say "GUEST CRASHED IN GUEST CONSOLE", what actually
happens? Can you post the output? Have you seen this post 11486, or 
has it gone away? 

Can you let us know what guest and guest config you are using? 

Testing with a debug build of Xen will also help.

This is probably the same as #2, just taking a different path through
Xen. Have you seen this post 11486, or has it gone away? 

[Again: guest, guest config, debug xen]

May be related to #2 and #3. 

[Again: guest, guest config, debug xen] 



cheers,
