The preempt notifiers hook call kvm_arch_vcpu_load / kvm_arch_vcpu_put, which won't unlock the vcpu mutex, right? I worry about a possible deadlock where some other operation that requires the vcpu mutex happens but the vcpu thread itself is in hlt. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
