[Xen-users] domain crash when using VMFUNC

[liuweijie <liuwj0129@xxxxxxx>]

Dear list,

When I use VMFUNC instructions on a HVM, domain crashes sometimes. 

My serial console shows like this:

domain_crash called from p2m.c:2204
Domain 1 (vcpu#0) crashed on cpu#7
……

I can provide more logs if needed.

The altp2m’s hypercalls are invoked before VMFUNC instructions are executed. 
And 10 alternative P2Ms can be built successfully.

Any help is appreciated! Thanks!

Cheers,
Weijie.
