Keir, You are right. There is a 32bit exception bitmap field for the vmexit control. It covers the first 32 interrupts/exceptions such as page faults gp faults, int3, into etc. int instruction interrupts start after that. And the vmexit due to int instructions can not be avoided.

That would seem to avoid the problem totally (as the original >'int 0xff' wouldn't vmexit), but it looks like maybe it's not possible. > > -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
