[Xen-devel] [PATCH] xen: reset creation_finished flag on soft reset

2017-09-01 Thread Vitaly Kuznetsov
C/s e7dabe5 ("x86/hvm: don't unconditionally create a default ioreq server") broke soft reset when QEMU traditional is being used. During soft reset QEMU is relaunched and default ioreq server needs to be re-created upon first HVM_PARAM_*IOREQ_* request. The flag will be set back to 'true' when too
