KVM: MMU: audit: allow audit more guests at the same time
It only allows to audit one guest in the system since: - 'audit_point' is a glob variable - mmu_audit_disable() is called in kvm_mmu_destroy(), so audit is disabled after a guest exited this patch fix those issues then allow to audit more guests at the same time Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
