[Xen-users] domain crash when using VMFUNC

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!
