From 72323dd3d971b51d2112cc3cea13443a440fa35e Mon Sep 17 00:00:00 2001 From: Amit Shah Date: Mon, 8 Aug 2011 11:41:10 -0300 Subject: [RHEL6 qemu-kvm PATCH 65/65] do not reset no_shutdown after we shutdown the vm RH-Author: Amit Shah Message-id: <2b3c51f2c664f79c2a28dd81c44623983765dcaf.1312803662.git.amit.shah@redhat.com> Patchwork-id: 31060 O-Subject: [RHEL6.2 qemu-kvm PATCH v2 1/1] do not reset no_shutdown after we shutdown the vm Bugzilla: 728464 RH-Acked-by: Alon Levy RH-Acked-by: Arnon Gilboa RH-Acked-by: Amos Kong From: Wen Congyang Daniel P. Berrange sent a libvirt's patch to support reboots with the QEMU driver. He implements it in json model like this: 1. add -no-shutdown in the qemu's option: qemu -no-shutdown xxxx 2. shutdown the vm by monitor command system_powerdown 3. wait for shutdown event 4. reset the vm by monitor command system_reset no_shutdown will be reset to 0 if the vm is powered down. We only can reboot the vm once. If no_shutdown is not reset to 0, we can reboot the vm many times.

Upstream qemu-kvm.git doesn't have this and behaves as expected.] Bugzilla: 728464 Signed-off-by: Amit Shah --- vl.c | 2 -- 1 files changed, 0 insertions(+), 2 deletions(-) Signed-off-by: Eduardo Habkost --- vl.c | 2 -- 1 files changed, 0 insertions(+), 2 deletions(-) diff --git a/vl.c b/vl.c index e7e6d83..afcf4db 100644 --- a/vl.c +++ b/vl.c @@ -3161,7 +3161,6 @@ static int vmstop_requested; int qemu_no_shutdown(void) { int r = no_shutdown; - no_shutdown = 0; return r; } @@ -4096,7 +4095,6 @@ static void main_loop(void) monitor_protocol_event(QEVENT_SHUTDOWN, NULL); if (no_shutdown) { vm_stop(0); - no_shutdown = 0; } else break; } -- 1.7.3.2
