From 2067e31bf97667eab9f111b496f5e9a44e827c5b Mon Sep 17 00:00:00 2001 From: Jiri Denemark Date: Tue, 27 Mar 2012 13:32:43 +0200 Subject: [PATCH] qemu: Avoid entering monitor with locked driver This avoids possible deadlock of the qemu driver in case a domain is begin migrated (in Begin phase) and unrelated connection to qemu driver is closed at the right time. I checked all callers of qemuDomainCheckEjectableMedia() and they are calling this function with qemu driver locked. --- src/qemu/qemu_hotplug.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index f1c1283c75..38163badb8 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -160,9 +160,9 @@ qemuDomainCheckEjectableMedia(struct qemud_driver *driver, int ret = -1; int i; - qemuDomainObjEnterMonitor(driver, vm); + qemuDomainObjEnterMonitorWithDriver(driver, vm); table = qemuMonitorGetBlockInfo(priv->mon); - qemuDomainObjExitMonitor(driver, vm); + qemuDomainObjExitMonitorWithDriver(driver, vm); if (!table) goto cleanup; -- GitLab
